Description

  The present invention relates to a securities trading system and program configured by a computer that executes securities trading processing, and can be used, for example, in a government bond trading system that executes trading of interest-bearing national treasury bonds. it can.

  In general, in the PTS market (proprietary trading system) where stocks are traded, the buyer or seller specifies the brand, quantity, trading category, and order price (unit price) when placing an order. To do.

  On the other hand, when forming a PTS market for buying and selling individual interest-bearing government bonds (fluctuating, 10 years), the price of government bonds with a face value of 100 yen is fixed at 100 yen, that is, buying and selling at the face value. It is possible to form a market for trading. In interest-bearing government bonds for individuals (variation, 10 years), interest (coupon) determined based on the interest level at that time is not fixed until redemption, but interest varies according to fluctuations in interest rates in the city. This is because there is no need for an adjustment operation such as raising or lowering the sales unit price to compensate for the difference between the interest (coupon) and the interest rate in the city. When such a market is formed, it is no longer necessary for the buyer or seller to specify the order price (unit price) when placing an order, and the brand, par value corresponding to the quantity, and the trading category are specified. It will be better.

  As a technique related to the present invention, Patent Literature 1 and Patent Literature 2 describe that the transaction market system of personal government bonds is made to the Zaraba system and the boarding system, and the board information is displayed. Patent Document 3 describes a system that mediates bond transactions between individuals by adopting a method of matching seller and buyer orders on the condition of delivery date. Patent Document 4 describes an order processing apparatus that specifies a substitute item from an inventory file and places an order for a substitute item when the ordered item is not in stock.

  As mentioned above, when a trading transaction for individual interest-bearing government bonds (floating, 10 years) is realized in the PTS market, when placing an order, the buyer or seller, You can specify the trading category, but unless you specify the brand you want to trade, you can't establish a trading transaction. There was only an opportunity to trade the brand.

  On the other hand, personal interest-bearing government bonds (fluctuation: 10 years) are currently issued four times a year (January, April, July, October) and the interest payment date is every six months. The applicable interest rate (coupon) between odd-numbered issues will be the same due to the timing of issue of the bonds and the timing of interest payment on the 13th bond, etc., and the applicable interest rate (coupon) between even-numbered issues will be the same. It will be the same. For this reason, there is no significant difference in attributes in each issue except for the maturity period. Therefore, it can be said that it is the redemption period that occupies a large weight when a customer decides a brand (number) to be traded. That is, it is expected that the redemption date is first determined and then the odd number or even number is selected from the size of the applicable interest rate (coupon).

  Therefore, it is desired to construct a trading processing system that satisfies the customer's transaction wishes determined based on the product characteristics of personal interest-bearing government bonds (fluctuation: 10 years). In addition, not only for individual interest-bearing government bonds (fluctuation: 10 years), but also for securities having similar product characteristics, it is desirable to construct a similar transaction processing system.

  An object of the present invention is to provide a securities trading processing system and program capable of satisfying a customer's transaction wishes determined based on product characteristics of securities and various customer's transaction wishes.

The present invention is a securities trading processing system configured by a computer that executes trading processing of securities,

If the order classification received by the order reception processing means is information indicating buy, the purchase data for execution is created using the order data, and the created purchase order data for execution Is stored in the purchase order storage means in association with the order identification information, and when the order classification received by the order reception processing means is information indicating selling, Execution preparation processing for creating execution target sell order data using the order data, and executing the processing for storing the created execution target sell order data in the sales order storage means in association with the order identification information Means,
The purchase order quantity of the reference brand stored in the purchase order storage means as the order quantity of the purchase order data to be executed in association with the same brand identification information, and the sell order storage means The sales order quantity stored as the order quantity of the sales order data to be executed is matched, and the amount corresponding to the purchase order quantity and the sell order quantity for these same brands is the fixed amount of the buy and sell orders. And when the unordered remaining order quantity occurs in the purchase order quantity of the reference brand, the brand identification information of the purchase order data to be executed is set in accordance with the priority stored in the order data storage means. The execution order is stored in the purchase order storage means in association with the same brand identification information in the state where the brand identification information on the alternative brands of the next priority is sequentially replaced. The purchase order quantity of the alternative brand stored as the remaining order quantity of the elephant buy order data is matched with the sell order quantity stored as the remaining order quantity of the sell order data to be executed in the sell order storage means , A transaction execution processing means for repeatedly executing a process of determining the amount corresponding to the buy order quantity and the sell order quantity for the same brand as the contract quantity of the buy order and the sell order,
The above-mentioned constant identification amount of the purchase order determined by the transaction execution processing means, the above-mentioned customer identification information of the execution target purchase order data, the above-mentioned reference identification or the above-mentioned alternative identification The execution target sell order data in which the contract amount of the sell order is contracted and stored in correspondence with the buy / sell classification information, the order identification information, and the information indicating purchase. A transfer processing database for storing as sales order contract data in association with the trading classification, the customer identification information, the brand identification information, the order identification information, and the information indicating sale;
When the trade classification of the contract data stored in the transfer processing database is information indicating buying, the contract constant amount of the contract data is the same as the customer identification information and the brand identification information of the contract data. To the securities balance data stored in the customer account database in association with the customer identification information and the same brand identification information, and the price equivalent amount of the contract amount of the contract data is The contract data stored in the transfer processing database is executed by executing transfer processing for a purchase order that is subtracted from the fund balance data stored in the customer account database in association with the same customer identification information as the customer identification information. If the trade classification is information indicating sale, the contract amount of the contract data is set to the contract data of the contract data. The customer identification information and the same customer identification information as the brand identification information and the same brand identification information are subtracted from the securities balance data associated with the same brand identification information and stored in the customer account database, and the contract amount of the contract data A transfer that executes a transfer process for selling order that adds the amount equivalent to the money balance data stored in the customer account database in association with the same customer identification information as the customer identification information of the contract data And a processing means.

  Here, as the “securities”, personal bonds for individuals with variable interest rates are suitable, but other bonds, stocks, and the like may be used. The same applies to the following inventions.

  Further, if “one-to-one correspondence” can be maintained, the “customer identification information” is converted into another type of customer identification information in the middle of the processing of the system of the present invention. You may mix. For example, in the situation where each customer's data is managed in association with the account number as customer identification information in the customer account database, the account number itself is input as customer identification information when order data is received by the order reception processing means. However, the customer identification information other than the account number (for example, telephone number, e-mail address, customer code, etc.) is input, and in the process of the system of the present invention, Conversion from customer identification information to an account number may be performed as appropriate. When such conversion is performed, a customer database that stores correspondence relationships between a plurality of types of customer identification information may be provided. In the claims of the present application, the conversion of the type of customer identification information in each processing process does not affect the essence of the invention, so that it is unified with “customer identification information” for convenience of description. The same applies to the following inventions.

  Furthermore, "the process of determining the amount of purchase order and sell order corresponding to the buy order quantity and sell order quantity for the same brand" as the contract quantity of the buy order and sell order means that the purchase order quantity and the sell order quantity are: This is the process of setting the smaller quantity as the contracted quantity for both the buy and sell orders. If the buy order quantity is smaller, all the buy order quantities are filled, If the same quantity is filled and the rest is unfilled, but if the sell order quantity is smaller, the sell order quantity is filled, and the same quantity as the sell order quantity in the buy order quantity. This is a process of making a contract and making the rest uncommitted. The same applies to the following inventions.

  In such a securities trading processing system of the present invention, a customer makes a purchase order by giving a priority to a plurality of issues, and when receiving a purchase order with this priority, by a transaction execution processing means, If the purchase order quantity of the reference issue of the first priority is matched with the sell order quantity of the issue, and if there is an unfilled remaining order quantity in the purchase order quantity of the reference issue, the purchase order is made according to the priority. In the state where the issues are sequentially replaced with alternative issues of the second priority or lower, the purchase order quantity of the alternative issue is matched with the sell order quantity of the issue issue.

  For this reason, the customer can obtain many opportunities to purchase brands that meet the desired conditions by making a purchase order with priority, and can increase the number of trading opportunities. In addition, the possibility of execution is increased as compared with the case of the conventional buying and selling process in which only one brand to be traded is designated and ordered. Therefore, it is possible to revitalize trading transactions for securities and to increase the liquidity of securities, and not only buyers but also sellers can benefit. Is achieved.

  Further, in the securities trading processing system described above, the buy order is a buy order with priority, and the sell order is a normal sell order without priority. The selling order may be a selling order with a priority order, and the buying order may be a normal buying order without a priority order. Even when the trading is reversed in this way, the above-described buying order has a priority order. The same effect as the case of making a purchase order can be obtained.

That is, the present invention is a securities trading processing system configured by a computer that executes trading processing of securities,
Fund balance data indicating the balance of the customer's funds deposited in the account of the customer of the financial institution is stored in association with customer identification information, and possessed by the customer deposited in the account of the customer of the financial institution A customer account database that stores the securities balance data indicating the balance of the securities to be associated with the brand identification information of the securities and the customer identification information;

To the securities balance data stored in the customer account database in association with the customer identification information and the same brand identification information, and the price equivalent amount of the contract amount of the contract data is The contract data stored in the transfer processing database is executed by executing transfer processing for a purchase order that is subtracted from the fund balance data stored in the customer account database in association with the same customer identification information as the customer identification information. If the trade classification is information indicating sale, the contract amount of the contract data is set to the contract data of the contract data. The customer identification information and the same customer identification information as the brand identification information and the same brand identification information are subtracted from the securities balance data associated with the same brand identification information and stored in the customer account database, and the contract amount of the contract data A transfer that executes a transfer process for selling order that adds the amount equivalent to the money balance data stored in the customer account database in association with the same customer identification information as the customer identification information of the contract data And a processing means.

  In addition, you may adopt the method (similar to the so-called plate approach method) that performs the contract processing at a predetermined contract processing time, and the method that performs the contract processing every time an order is placed on the market (similar to the so-called Zaraba method) In the following description, the contract processing method is divided and described.

  <When adopting a method for executing contract processing at a predetermined contract processing time (a method similar to the so-called plate-shifting method)>

In this case, in the securities trading system described above,
The execution preparation processing means is
When the trading category of the order data received by the order reception processing means is information indicating buying, the customer identification information, the brand identification information about the reference brand, and the execution target including the order quantity Executing a process of storing the purchase order data in the purchase order storage means in association with the order identification information;
If the trading category of the order data received by the order acceptance processing means is information indicating sale, the customer identification information, the brand identification information about the securities to be sold, and the order quantity The sales order data to be executed is associated with the order identification information and stored in the sales order storage means,
The transaction execution processing means is:
Stored as the order quantity of the purchase order data to be executed in the purchase order storage means in association with the same brand identification information at the time of at least one predetermined processing time of the day. The buy order quantity of the reference brand is matched with the sell order quantity stored as the order quantity of the sell order data to be executed in the sell order storage means, and the buy order quantity and the sell order for these same brands Execute the first sales transaction process to determine the amount corresponding to the quantity as a constant quantity of buy and sell orders,
If an unfilled remaining order quantity among the purchase orders of the reference issue is generated in the first trading transaction processing, the purchase order data for the execution target for which the remaining order quantity has occurred is used for the purchase order. According to the priority order, using the brand identification information and the priority order for the alternative brand stored in the order data storage means in association with the same order identification information as the order identification information stored in the storage means The brand replacement process for replacing the brand identification information stored in the purchase order storage means for the execution target buy order data in which the remaining order quantity is generated from the standard brand to the brand identification information for the alternative brand Is stored in the purchase order storage means as the remaining order quantity of the purchase order data to be executed in association with the same brand identification information. The buy order quantity of the alternative brand is matched with the sell order quantity stored as the remaining order quantity of the sell order data to be executed in the sell order storage means, and the buy order quantity and the sell order for these same brands are matched. Execute the secondary sales transaction process to determine the amount corresponding to the quantity as the contract quantity of the buy and sell orders,
Furthermore, in the case of each trading transaction processing after the second trading transaction processing, there is an unfilled remaining order quantity among the purchase order quantities of the alternative brand, and there is designation of an alternative brand of the next priority The stock difference that replaces the stock identification information stored in the buy order storage means for the execution order buy order data in which the remaining order quantity has occurred is replaced with the stock identification information for the alternative stock of the next priority order And the purchase order quantity of the alternative brand of the next priority stored in the purchase order storage means as the remaining order quantity of the execution target buy order data associated with the same brand identification information. And the sell order quantity stored as the remaining order quantity of the sell order data to be executed in the sell order storage means, and the buy order quantity and the sell order quantity for these same brands are Third trading after the processing trade transaction processing repeatedly run to determine the amount that response as a contract quantity of buy orders and sell orders,
After the final purchase and sale transaction processing using the purchase order quantity of the alternative issue with the lowest priority, if there is a remaining order quantity that has not been filled in the purchase order quantity, the remaining order quantity has been generated. It may be configured to execute a brand replacement process for returning the brand identification information stored in the purchase order storage means for the purchase order data to be executed to brand identification information for the reference brand.

  Thus, in the case of adopting a method (a method similar to the so-called plate approach method) for executing the contract processing at a predetermined contract processing time (for example, in the case of FIGS. 8 and 9), first, by the execution preparation processing means, The purchase order data including the purchase order quantity of the reference issue is stored in the purchase order storage means, and the purchase order quantity of the reference issue in the purchase order data stored in the purchase order storage means and the same issue by the transaction execution processing means. If the unsettled remaining order quantity occurs in the buy order quantity, the trade execution processing means will then buy the purchase order data stored in the sell order storage means. Buy order storage means while replacing the stock in the purchase order data stored in the order storage means from the base stock to the alternative stock or from the alternative stock to the alternative stock of the next priority according to the priority order. And the purchase order quantity of alternative stocks of stored purchase order data, to be committed against the sales order quantity of the sales order data that has been stored in the order storage means sales for the same brand. Then, after a trading transaction process using the purchase order quantity of the issue with the lowest priority, if an uncommitted remaining order quantity occurs in the purchase order quantity, the transaction execution processing means stores it in the purchase order storage means. The brand of the purchased purchase order data is returned to the base brand and prepared for the contract processing performed at the next contract processing time. As a result, even if there are multiple buy orders with priorities and multiple sell orders, it is possible to satisfy the customer's transaction wishes indicated by the respective prioritized buy orders. .

  Further, in the securities trading processing system described above, the buy order is a buy order with priority, and the sell order is a normal sell order without priority. The selling order may be a selling order with a priority order, and the buying order may be a normal buying order without a priority order. Even when the trading is reversed in this way, the above-described buying order has a priority order. The same effect as the case of making a purchase order can be obtained.

That is, in the securities trading system described above,
The execution preparation processing means is
If the order classification received by the order acceptance processing means is information indicating sale, the customer identification information, the brand identification information about the reference brand, and the execution target including the order quantity Executing a process of storing sell order data in the sell order storage means in association with the order identification information;
If the trading category of the order data received by the order acceptance processing means is information indicating buying, the customer identification information, the brand identification information about the securities to be purchased, and the order quantity are included. The execution target purchase order data is configured to execute processing for storing the purchase order storage unit in association with the order identification information,
The transaction execution processing means is:
Stored as the order quantity of the sell order data to be executed in the sell order storage means in association with the same brand identification information at the time of at least one predetermined processing time of the day. The selling order quantity of the reference brand is matched with the buying order quantity stored as the order quantity of the buying order data to be executed in the buying order storage means, and the selling order quantity and the buying order for these same brands. Execute the first sales transaction process to determine the amount corresponding to the quantity as a constant quantity of sell order and buy order,
If an unfilled remaining order quantity among the selling orders of the standard issue is generated in the first trading transaction process, the execution order selling order data in which the remaining order quantity is generated is used for the selling order. According to the priority order, using the brand identification information and the priority order for the alternative brand stored in the order data storage means in association with the same order identification information as the order identification information stored in the storage means The brand replacement process for replacing the brand identification information stored in the selling order storage means with respect to the execution order sell order data in which the remaining order quantity has occurred, from the standard brand to the brand identification information on the alternative brand Is executed before being stored in the selling order storage means as the remaining order quantity of the selling order data to be executed in association with the same brand identification information. The selling order quantity of the alternative brand is matched with the buying order quantity stored as the remaining order quantity of the buy order data to be executed in the buying order storage means, and the selling order quantity and the buying order for these same brands Execute the secondary sales transaction process to determine the amount corresponding to the quantity as the contract quantity of the sell order and the buy order,
Furthermore, in the case of each trading transaction processing after the second trading transaction processing, there is an unfilled remaining order quantity among the selling order quantities of the alternative brands, and there is designation of an alternative brand of the next priority order. The stock difference for replacing the stock identification information stored in the sell order storage means with respect to the execution order sell order data in which the remaining order quantity has occurred is replaced with the stock identification information for the alternative stock of the next priority order And the selling order quantity of the alternative brand of the next priority stored in the selling order storage means as the remaining order quantity of the selling order data to be executed in association with the same brand identification information. And the buy order quantity stored as the remaining order quantity of the buy order data to be executed in the buy order storage means, and the sell order quantity and the buy order quantity for these same brands are Third-order buying and selling transaction processing repeatedly buying and selling transaction processing after the execution to determine as a contract quantity of orders and purchase order sell a minute that response,
After the final sales transaction process using the selling order quantity of the alternative issue with the lowest priority, if there is a remaining order quantity that has not been filled in the selling order quantity, the remaining order quantity has been generated. It is good also as a structure which performs the brand replacement process which returns the said brand identification information memorize | stored in the said sales order memory | storage means about the sales order data of execution object to the brand identification information about the said reference brand.

  In addition, the configuration of the securities trading processing system in the case of adopting the method for executing the contract processing at the predetermined contract processing time described above (similar method to the so-called boarding method) is described in more detail as follows. It is desirable to do.

That is, in the securities trading system described above,
The execution preparation processing means is
Common order of buy orders and sell orders for managing the order data received by the order reception processing means with priority on the order of the customer previously ordered, or management of the order of acceptance of the buy order alone and the sell order alone Information,

If there is purchase order data to be executed that is stored in the purchase order storage means in association with the execution flag that is in a state indicating an unsettled state after the first sales transaction processing, The brand identification information about the alternative brand stored in the order data storage means in association with the same order identification information as the order identification information stored in the purchase order storage means for the target purchase order data, and Using the priority order, according to the priority order, the stock identification information stored in the buy order storage means in association with the execution flag indicating an unsettled state is stored from the reference stock to the alternative stock. Corresponding to the same brand identification information and the execution flag set to uncommitted after executing the brand replacement process to replace the brand identification information for The acceptance order management information indicating the early acceptance order of the purchase order quantity of the alternative brand stored in the buy order storage means and the sell order quantity stored in the sell order storage means. By matching the purchase order quantity and the sell order quantity for these same issues, the amount corresponding to the buy order and the sell order is determined as a constant quantity, and the buy order quantity or the total quantity of the sell order quantity is determined. Regarding the execution order buy order data or sell order data that has been executed, the execution flag has been updated from a not yet executed state to a closed state, and the purchase order quantity or a part of the sell order quantity has been executed. For the buy order data or sell order data to be executed, the contract is determined from the buy order quantity stored in the buy order storage means or the sell order quantity stored in the sell order storage means. By subtracting the amount performs a second-order trading process to update the purchase order quantity or the sales order quantity,
Further, after each sales transaction processing after the second sales transaction processing, the execution target purchase order data stored in the purchase order storage means in association with the contract flag in a state indicating unsettled. And there is a designation of an alternative issue of the next priority, the issue identification information stored in the purchase order storage means for the purchase order data to be executed is used for the next priority. The brand replacement process for replacing the brand identification information for the alternative brand, and the same brand identification information and the contract flag set to indicate the unsettled state are stored in the purchase order storage unit in association with the contract flag. Match the purchase order quantity of the alternative brand of the next priority and the sell order quantity stored in the sell order storage means in the order of the reception order management information indicating the early reception order, and Execution target for which the purchase order quantity and the sell order quantity corresponding to one brand are determined as the contract quantity of the buy order and the sell order, and the total quantity of the buy order quantity or the sell order quantity is executed For the purchase order data or sell order data, the execution flag is updated from unfilled to a state indicating closed, and the purchase order subject to execution is executed by executing the purchase order quantity or a part of the sell order quantity. For the data or sell order data, the buy order quantity stored by subtracting the contract quantity from the buy order quantity stored in the buy order storage means or the sell order quantity stored in the sell order storage means or Repeatedly execute the sales transaction processing after the third sales transaction processing to update the sell order quantity,
After the final sales transaction processing using the purchase order quantity of the alternative issue with the lowest priority order, it is stored in the purchase order storage means in association with the execution flag that is in a state indicating unsettled. When there is buy order data to be executed, the stock replacement that returns the brand identification information stored in the buy order storage means for the buy order data to be executed to the brand identification information for the reference brand It is desirable to have a configuration for executing processing.

  Here, the buy order quantity of each priority order stored in the buy order storage means and the sell order quantity stored in the sell order storage means are matched in the order of reception order management information indicating the early reception order. The process of “determining the amount corresponding to the buy order quantity and the sell order quantity for the same brand as the contract quantity of the buy order and the sell order” is the order of the buy order quantity and the sell order quantity. In this process, the smaller quantity is used as the contracted quantity for both the buy and sell orders. If the buy order quantity is smaller, all the buy order quantities are filled, and the buy order quantity out of the sell order quantities. This is a process in which the same quantity is executed and the remainder is not executed. Then, when contracting the same quantity as the purchase order quantity among the sell order quantities, the order management information indicating the early order of acceptance is executed in order from the given order. The sales order quantity of the sales order to which the reception order management information indicating is added is added until reaching the same quantity as the purchase order quantity, and at the certain sales order (the reception order management information indicating the earliest reception order It may be the first selling order that is given.) If a fraction occurs, the selling order is partially executed. On the other hand, when the sell order quantity is smaller, the sell order quantity is all filled, the same quantity as the sell order quantity is filled in the buy order quantity, and the remaining is the uncommitted quantity. Then, when filling the same quantity as the sell order quantity among the buy order quantities, the order is managed in order from the purchase order to which the acceptance order management information indicating the early acceptance order is given. The purchase order quantity of the purchase order given the reception order management information is added until the same quantity as the sell order quantity is reached, and at a certain purchase order (the reception order management information indicating the earliest reception order It may be the place of the first purchase order given.) When a fraction occurs, the purchase order is partially executed. The same applies to the following inventions.

  In this way, when the contract processing using the reception order management information is performed, it is possible to realize the time priority principle that the order data of the customer who has previously ordered is preferentially executed. Therefore, when a buy order of the same brand or a sell order of the same brand competes, the customer who has made a purchase order or a sell order first has priority. In addition, stocks in the buy order will be replaced in order, such as the standard stock of the first priority, the alternative stock of the second priority, and the substitute stock of the next priority. The principle applies when stocks with the same priority are matched, and when the stocks match but the priorities of those stocks are different, the order reception time Regardless of the order of purchase, the purchase order with the high-priority issue is preferentially executed. For example, the purchase order data of the customer A previously ordered has the brand Y as the alternative brand of the second priority, and the purchase order data of the customer B ordered later has the brand Y as the reference brand of the first priority. If the buy orders of these brands Y are in competition, the customer B's buy order data is received later, but since it is the first priority standard brand, Is preferentially executed by the purchase order data of the customer B (see the example in FIG. 9).

  Further, in the securities trading processing system described above, the buy order is a buy order with priority, and the sell order is a normal sell order without priority. The selling order may be a selling order with a priority order, and the buying order may be a normal buying order without a priority order. Even when the trading is reversed in this way, the above-described buying order has a priority order. The same effect as the case of making a purchase order can be obtained.

That is, in the securities trading system described above,
The execution preparation processing means is
Common order of buy orders and sell orders for managing the order data received by the order reception processing means with priority on the order of the customer previously ordered, or management of the order of acceptance of the buy order alone and the sell order alone Information,
When storing the new execution target purchase order data in the purchase order storage means, the new execution target purchase order data includes the order identification information, an execution flag indicating an uncommitted state, and Storing it in association with the reception order management information,

The transaction execution processing means is:
Stored in the selling order storage unit in association with the same brand identification information and the unsettled contract flag at least at a predetermined contract processing time in a day. Further, the sales order quantity of the reference brand and the purchase order quantity stored in the storage unit for purchase order are matched in the order of the reception order management information indicating the early reception order, and the sales order for these same brands The sales order data or the buy order to be executed, in which the quantity corresponding to the quantity and the buy order quantity is determined as a contract quantity of the sell order and the buy order, and the sell order quantity or the entire quantity of the buy order quantity is executed. For the data, the execution flag updated from the unsettled state to the filled state indicating the contracted state, and the sell order data to be executed or a part of the buy order quantity is executed or For the order data, the sell order quantity or the buy order is obtained by subtracting the contract amount from the sell order quantity stored in the sell order storage means or the buy order quantity stored in the buy order storage means. Execute the first transaction transaction to update the quantity,
If there is sell order data to be executed that is stored in the selling order storage means in association with the contract flag that is in a state indicating unsettled after the first sales transaction processing, The brand identification information for the alternative brand stored in the order data storage means in association with the same order identification information as the order identification information stored in the sell order storage means for the target sell order data, and Using the priority order, according to the priority order, the stock identification information stored in the selling order storage means in association with the contract flag in a state indicating unsettled is obtained from the reference stock to the substitute stock. Corresponding to the same brand identification information and the execution flag set to uncommitted after executing the brand replacement process to replace the brand identification information for The acceptance order management information indicating the early acceptance order of the sell order quantity of the alternative brand stored in the sell order storage means and the buy order quantity stored in the purchase order storage means. The sales order quantity and the purchase order quantity corresponding to these same brands are matched in order, and the sales order quantity and the buy order quantity are determined as a constant quantity, and the sell order quantity or the total quantity of the buy order quantity is determined. For the sales order data or purchase order data subject to execution, the contract flag is updated from unfilled to a state indicating closed, and the sell order quantity or a part of the buy order quantity is filled. With regard to sell order data or buy order data to be executed, the contract is determined from the sell order quantity stored in the sell order storage means or the buy order quantity stored in the buy order storage means. By subtracting the amount performs a second-order trading process of updating the sales order quantity or the purchase order quantity,
Further, after each sales transaction processing after the second sales transaction processing, the execution target sell order data stored in the sell order storage means in association with the contract flag in a state indicating unsettled. And there is designation of an alternative stock of the next priority, the stock identification information stored in the sell order storage means for the sell order data to be executed is used for the next priority. The brand replacement process for replacing the brand identification information for the alternative brand, and the same brand identification information and the contract flag set to indicate the unsettled state are stored in the selling order storage unit in association with the execution flag. The selling order quantity of the alternative brand of the next priority and the buy order quantity stored in the buying order storage means are matched in the order of the receiving order management information indicating the early receiving order, Execution target for which the quantity corresponding to the sell order quantity and the buy order quantity for one brand is determined as the contract quantity of the sell order and the buy order, and the total quantity of the sell order quantity or the buy order quantity is executed For the sell order data or the buy order data of the execution order, the execution flag is updated from the unsettled state to the closed state, and the sell order quantity or a part of the buy order quantity is executed to execute For the data or buy order data, the sell order quantity stored by subtracting the contract quantity from the sell order quantity stored in the sell order storage means or the buy order quantity stored in the buy order storage means, or Repeatedly execute the sales transaction processing after the third sales transaction processing to update the buy order quantity,
Stored in the selling order storage means in association with the execution flag that is in a state indicating unsettled after the final sales transaction processing using the selling order quantity of the alternative issue with the lowest priority. If there is the selling order data to be executed, the brand replacement for returning the brand identification information stored in the selling order storage means for the selling order data to be executed to the brand identification information for the reference brand It is good also as a structure which performs a process.

  <Each time when a new order is placed on the market, a system that immediately executes the contract (similar to the so-called Zaraba method) and uses the order of the purchase order data to be executed that has been placed on the market. If you want to replace sequentially according to

In this case, in the securities trading system described above,
The execution preparation processing means is
When the trading category of the order data received by the order reception processing means is information indicating buying, the customer identification information, the brand identification information about the reference brand, and the execution target including the order quantity Executing a process of storing the purchase order data in the purchase order storage means in association with the order identification information;
If the trading category of the order data received by the order acceptance processing means is information indicating sale, the customer identification information, the brand identification information about the securities to be sold, and the order quantity The sales order data to be executed is associated with the order identification information and stored in the sales order storage means,
The transaction execution processing means is:
It consists of transaction execution processing means at the time of purchase order reception and transaction execution processing means at the time of sales order reception,
The transaction execution processing means at the time of purchase order reception is:

Execute transaction processing,
If an unfilled remaining order quantity among the purchase orders of the reference issue is generated in the first trading transaction processing, the purchase order data for the execution target for which the remaining order quantity has occurred is used for the purchase order. According to the priority order, using the brand identification information and the priority order for the alternative brand stored in the order data storage means in association with the same order identification information as the order identification information stored in the storage means The brand replacement process for replacing the brand identification information stored in the purchase order storage means for the execution target buy order data in which the remaining order quantity is generated from the standard brand to the brand identification information for the alternative brand , The purchase order quantity of the alternative brand stored as the remaining order quantity of the purchase order data to be executed in the purchase order storage means, and the purchase order to be executed Sell order quantity associated with the same brand identification information as the brand identification information for the alternative brand included in the data and stored in the sell order storage means as the remaining order quantity of the sell order data to be executed Match, and execute the secondary sales transaction processing to determine the amount of the buy order and sell order as a constant amount corresponding to the buy order quantity and the sell order quantity for these same issues,
Furthermore, in the case where each remaining transaction process after the second transaction process results in an unfilled remaining order quantity among the purchase order quantities of the alternative brand, and there is a designation of an alternative brand of the next rank The stock replacement replaces the stock identification information stored in the purchase order storage means for the execution order buy order data in which the remaining order quantity has occurred with the stock identification information for the alternative stock of the next priority order. Processing, and the purchase order quantity of the alternative issue of the next priority stored in the buy order storage means as the remaining order quantity of the purchase order data to be executed, and the buy order quantity included in the execution target buy order data The number of sell orders stored in the sell order storage means as the remaining order quantity of the execution target sell order data in association with the same brand identification information as the brand identification information for the alternative brand of the next priority , And repeats the purchase and sale transaction processing after the third sale transaction processing to determine the amount of the purchase order and the sale order corresponding to the purchase order quantity and the sale order quantity for these same issues. Run,
After the final purchase and sale transaction processing using the purchase order quantity of the alternative issue with the lowest priority, if there is a remaining order quantity that has not been filled in the purchase order quantity, the remaining order quantity has been generated. It is configured to execute a brand replacement process for returning the brand identification information stored in the purchase order storage means for the purchase order data to be executed to brand identification information for the reference brand,
The transaction execution processing means at the time of accepting a selling order is:
Each time new execution target sell order data is stored in the sell order storage means by the execution preparation processing means, the sell order of the new execution target sell order data stored in the sell order storage means The reference for the execution order buy order data stored in the purchase order storage means in association with the quantity and the same brand identification information as the brand identification information included in the new execution target sell order data Executes the first trading transaction process that matches the purchase order quantity of the brand and determines the amount of the purchase order and sell order corresponding to these same brands as the constant quantity of the buy and sell orders.

On the other hand, when new selling order data is received, the brand of the buying order data that has already been received and stored in the buying order storage means is the reference brand (buying order data with new priority order). This is because the brand of the buy order that has been uncommitted and generated the remaining order quantity after a series of processing when the order is received has returned to the standard brand.) Is stored in the purchase order storage means. New selling order data stored in the selling order storage means while sequentially replacing the stocks in the buying order data according to the priority order from the base stock to the alternative stock or from the alternative stock to the alternative stock of the next priority. And purchase / buy order data for which the brand is replaced (see FIG. 13). As a result, it is possible to satisfy the customer's transaction desire indicated by the priority order purchase order when receiving a priority order purchase order or when receiving a normal order without priority order. As well as being possible, it is possible to increase the liquidity of securities by increasing the possibility of closing sales orders.

  Further, in the securities trading processing system described above, the buy order is a buy order with priority, and the sell order is a normal sell order without priority. The selling order may be a selling order with a priority order, and the buying order may be a normal buying order without a priority order. Even when the trading is reversed in this way, the above-described buying order has a priority order. The same effect as the case of making a purchase order can be obtained.

That is, in the securities trading system described above,
The execution preparation processing means is

Furthermore, in the case where each remaining transaction process after the second sales transaction process results in an unfilled remaining order quantity among the sales order quantities of the alternative brand, and there is a designation of an alternative brand of the next rank Is a brand replacement that replaces the brand identification information stored in the sell order storage means with respect to the execution order sell order data for which the remaining order quantity has occurred, with brand identification information for the next priority alternative brand Processing, the sell order quantity of the alternative brand of the next priority stored as the remaining order quantity of the execute order sell order data in the sell order storage means, and the sell order data included in the execute target sell order data The number of purchase orders stored as the remaining order quantity of the purchase order data to be executed in the purchase order storage means in association with the same brand identification information as the brand identification information for the alternative brand of the next priority , And repeats the sales transaction processing after the third sales transaction processing, which determines the amount corresponding to the sell order quantity and the buy order quantity for these same issues as the contract quantity of the sell order and the buy order. Run,
After the final sales transaction process using the selling order quantity of the alternative issue with the lowest priority, if there is a remaining order quantity that has not been filled in the selling order quantity, the remaining order quantity has been generated. It is configured to execute a brand replacement process for returning the brand identification information stored in the selling order storage means with respect to execution order sell order data to brand identification information about the reference brand,
The transaction execution processing means at the time of purchase order reception is:
Each time the execution preparation processing means stores new execution target purchase order data in the purchase order storage means, the purchase order of the new execution target purchase order data stored in the purchase order storage means The reference of the execution target sell order data stored in the sell order storage unit in association with the quantity and the same brand identification information as the brand identification information included in the new execution target buy order data Execute the first sales transaction process that matches the sell order quantity of the brand and determines the amount of the sell order and the buy order quantity corresponding to these same brands as the constant quantity of the sell order and the buy order.

The selling order data to be executed according to the priority order using the brand identification information and the priority order for the alternative brand stored in the order data storage means in association with the same order identification information as the information All the execution target selling orders with the remaining order quantity are replaced with a brand replacement process for replacing the brand identification information stored in the selling order storage means from the standard brand to the brand identification information about the alternative brand. The stock identification information about the replacement stock that is executed on the data or replaced is the purchase order data of the execution target subject to execution of the remaining order quantity. After executing only the sell target data to be executed which is the same as the brand identification information stored in the sentence storage means, the remaining order of the buy order data to be executed in the buy order storage means The buy order quantity stored as a quantity and the same brand identification information as the brand identification information included in the execution target buy order data are associated with the execution order sell order data in the sell order storage means. The selling order quantity of the alternative brand stored as the remaining order quantity is matched, and the amount corresponding to the selling order quantity and the buying order quantity for these same brands is determined as the contract quantity of the selling order and the buying order. To execute the second trading transaction processing,
Furthermore, an unfilled remaining order quantity of the purchase order quantity is generated in each sale transaction process after the second sale transaction process, and an alternative brand of the next rank is designated in the execution order sale order data.

The transaction execution processing means at the time of accepting a selling order is:
Each time new execution target sell order data is stored in the sell order storage means by the execution preparation processing means, the sell order of the new execution target sell order data stored in the sell order storage means The reference for the execution order buy order data stored in the purchase order storage means in association with the quantity and the same brand identification information as the brand identification information included in the new execution target sell order data The purchase order quantity of the brand is matched in the order of the reception order management information indicating the early reception order, and the amount corresponding to the purchase order quantity and the sell order quantity for these same brands is matched with the purchase order and the sell order. With regard to buy order data or sell order data subject to execution, which is determined as a contract amount, and the entire quantity of the buy order quantity or the sell order quantity is executed, the execution flag is set to “completed” or “closed”. For the purchase order data or sell order data to be executed with the purchase order quantity or part of the sell order quantity being executed, the purchase order stored in the purchase order storage means is updated. Executing a first order transaction process for updating the buy order quantity or the sell order quantity by subtracting the constant quantity from the sell order quantity stored in the quantity or the sell order storage means;
After the first sales transaction processing, if there is the selling order data to be executed stored in the selling order storage means in association with the contract flag set to indicate the unsettled state, the execution The brand identification information about the alternative brand stored in the order data storage means in association with the same order identification information as the order identification information stored in the purchase order storage means for the target purchase order data, and Using the priority order, in accordance with the priority order, the brand identification information stored in the purchase order storage means for the purchase order data to be executed is replaced with the brand identification information for the alternative brand from the reference brand. The stock replacement process is executed for all the execution target purchase order data associated with the execution flag that is in a state indicating unsettled, or Is stored in the selling order storage means with respect to the selling order data of the execution target associated with the execution flag in which the brand identification information about the alternative brand after replacement is in a state indicating unsettled After executing only the buy order data subject to execution, which is the same brand identification information as the brand identification information, the sell order quantity stored as the remaining order quantity of the sell order data subject to execution is stored in the sell order storage unit; The alternative stored in the purchase order storage means in association with the same brand identification information as the brand identification information included in the execution target sell order data, as the remaining order quantity of the execution target buy order data Match the purchase order quantity of the brand in the order of the reception order management information indicating the early reception order, and the quantity corresponding to the purchase order quantity and the sell order quantity for these same brands For the execution order buy / sell data, which is determined as the contract quantity of the buy / sell order and the contract quantity of the buy / sell order quantity or the total quantity of the sell order quantity is fulfilled, the execution flag is filled from unfilled The purchase order data or the sell order data to be executed, in which the purchase order quantity or a part of the sell order quantity is executed, is updated to the state indicating the purchase order quantity, and the purchase order stored in the purchase order storage means Executing a secondary sales transaction process of subtracting the approximate constant amount from the order quantity or the sell order quantity stored in the sell order storage means to update the buy order quantity or the sell order quantity;
Further, after each sales transaction processing after the second sales transaction processing, the execution target sell order data stored in the sell order storage means in association with the contract flag in a state indicating unsettled. And there is a designation of an alternative brand of the next rank in the execution order buy order data, the brand identification information stored in the buy order storage means for the execution order buy order data is , A stock replacement process for replacing the stock identification information for the alternative stock of the next priority, a sell order quantity stored as a remaining order quantity of the sell order data to be executed in the sell order storage means, and Corresponding to the same brand identification information as the brand identification information included in the sell order data to be executed, stored in the buy order storage means as the remaining order quantity of the buy order data to be executed Further, the purchase order quantity of the alternative brand of the next priority is matched in the order of the reception order management information indicating the early reception order, and the purchase order quantity and the sell order quantity for these same brands correspond to each other. For the buy order data or sell order data subject to execution in which the minutes are determined as the contract amount of the buy order and the sell order, and the total quantity of the buy order quantity or the sell order quantity is executed, the execution flag is set from uncommitted. The purchase order data or the sell order data to be executed, which is updated to a state indicating a contracted execution, and a part of the buy order quantity or the sell order quantity is executed, is stored in the buy order storage means. A third sales transaction process for updating the buy order quantity or the sell order quantity by subtracting the approximate constant quantity from the sell order quantity stored in the buy order quantity or the sell order storage means. Repeatedly executes the subsequent sale transaction processing,
After the final sales transaction processing using the purchase order quantity of the alternative issue with the lowest priority order, it is stored in the purchase order storage means in association with the execution flag that is in a state indicating unsettled. When there is buy order data to be executed, the stock replacement that returns the brand identification information stored in the buy order storage means for the buy order data to be executed to the brand identification information for the reference brand It is desirable to have a configuration for executing processing.

  In this way, when the contract processing using the reception order management information is performed, it is possible to realize the time priority principle that the order data of the customer who has previously ordered is preferentially executed. Therefore, when a buy order of the same brand or a sell order of the same brand competes, the customer who has made a purchase order or a sell order first has priority. In addition, when new purchase order data is received, if the purchase order quantity that has not yet been agreed with the purchase order data received before then remains in the purchase order storage means as the purchase order quantity of the reference issue However, since there is no sell order quantity for the same issue, there is virtually no competition between those purchase orders, but a series of new purchase order data while replacing the issue. If there is a remaining order quantity after the trading process, if the new buy order data standard stock matches the base stock of the previously accepted buy order data, then the new sell order data Are accepted, these buy orders will compete and the previously accepted buy orders will be preferentially executed. Further, when new selling order data is received, the stocks of the buy order are sequentially replaced with the first priority base issue, the second priority alternative issue, the next priority alternative issue, and so on. However, for buy orders, the time-priority principle is applied when the same-priority issues match, and even if each other's issues match, If the priorities of the brands are different, the purchase order with the brand as a high priority brand is preferentially executed regardless of the order reception time. For example, the purchase order data of the customer A that has been previously ordered has the brand Y as the alternative brand of the second priority (the customer A's buy order data is used for the buy order as the buy order of the brand X as the base brand. The purchase order data of the customer B ordered later has the brand Y as the reference brand of the first priority (the customer B buy order data is the reference brand). It remains in the buy order storage means as a purchase order for the brand Y.) When new sell order data for the brand Y is received, the purchase order data for the customer B is received later. Since the reference stock has the first priority order, the purchase order data of the customer B is preferentially executed for the competing stock Y.

  Further, in the securities trading processing system described above, the buy order is a buy order with priority, and the sell order is a normal sell order without priority. The selling order may be a selling order with a priority order, and the buying order may be a normal buying order without a priority order. Even when the trading is reversed in this way, the above-described buying order has a priority order. The same effect as the case of making a purchase order can be obtained.

That is, in the securities trading system described above,
The execution preparation processing means is

Run,
When the trade classification of the order data received by the order acceptance processing means is information indicating sale,
The sales order storage unit stores the customer identification information, the brand identification information about the securities to be sold, and the execution order sell order data including the order quantity in association with the order identification information. It is configured to execute processing,
The transaction execution processing means is:
It consists of transaction execution processing means at the time of purchase order reception and transaction execution processing means at the time of sales order reception,
The transaction execution processing means at the time of purchase order reception is:
Each time new execution order purchase order data is stored in the buy order storage means by the execution preparation processing means, the purchase order storage means stores the order quantity of the new execution target purchase order data. The purchase order quantity of the reference issue and the purchase order quantity of the alternative issue, and the issue identification information about the reference issue and the issue identification information about the alternative issue included in the new execution order purchase order data, respectively. The selling order quantity associated with the same brand identification information is matched with the selling order quantity stored as the order quantity of the selling order data to be executed in the selling order storage means, and the buy order quantity and the selling price for these same brands are matched. Executes the process of determining the amount corresponding to the order quantity as a fixed amount of buy and sell orders,
The transaction execution processing means at the time of accepting a selling order is:
Each time new execution target sell order data is stored in the sell order storage means by the execution preparation processing means, the sell order of the new execution target sell order data stored in the sell order storage means The reference for the execution order buy order data stored in the purchase order storage means in association with the quantity and the same brand identification information as the brand identification information included in the new execution target sell order data Executes the first trading transaction process that matches the purchase order quantity of the brand and determines the amount of the purchase order and sell order corresponding to these same brands as the constant quantity of the buy and sell orders. And
The order identification stored in the storage unit for purchase order with respect to the purchase order data to be executed when the unordered remaining order quantity is generated in the first order transaction process. The purchase order data to be executed according to the priority order using the brand identification information and the priority order for the alternative stock stored in the order data storage means in association with the same order identification information as the information All of the execution target purchase orders having a remaining order quantity are replaced with a brand replacement process for replacing the brand identification information stored in the storage means for purchase orders from the standard brand to brand identification information about the alternative brand. The stock identification information about the replacement stock that is executed on the data or replaced is the sales order data for the execution target sales order data in which the remaining order quantity has occurred. After executing only the purchase order data to be executed, which is the same brand identification information as the brand identification information stored in the sentence storage means, the remaining order of the execution order sell order data in the sell order storage means The sales order quantity stored as a quantity and the same brand identification information as the brand identification information included in the execution order sell order data are associated with the execution order purchase order data in the purchase order storage means. The buy order quantity of the alternative brand stored as the remaining order quantity is matched, and the amount corresponding to the buy order quantity and the sell order quantity for these same brands is determined as the contract quantity of the buy and sell orders. To execute the second trading transaction processing,
Furthermore, an unfilled remaining order quantity of the sales order quantity is generated in each sales transaction process after the second sales transaction process, and the designation of the alternative brand of the next rank is specified in the execution order purchase order data. If there is a brand replacement process for replacing the brand identification information stored in the buy order storage means with respect to the execution order buy order data to brand identification information about the alternative brand of the next priority, The selling order quantity stored as the remaining order quantity of the selling order data to be executed in the selling order storage means, and the same brand identification information as the brand identification information included in the selling order data to be executed Attached to the buy order quantity of the alternative brand of the next priority order stored in the buy order storage means and stored as the remaining order quantity of the buy order data to be executed, and these same brands For in the purchase and the order quantity and sales order quantity is repeatedly executed the trading process of the third-order sales transaction processing or later be determined as the contract quantity of to have divided the buy orders and sell orders corresponding,
After the final purchase and sale transaction processing using the purchase order quantity of the alternative issue with the lowest priority, if there is a remaining order quantity that has not been filled in the purchase order quantity, the remaining order quantity has been generated. It may be configured to execute a brand replacement process for returning the brand identification information stored in the purchase order storage means for the purchase order data to be executed to brand identification information for the reference brand.

  In this way, every time a new order is placed on the market, a method that immediately executes a contract (a method similar to the so-called Zaraba method) is adopted, and the purchase order quantity of the purchase order data is specified according to the priority order. In the case of placing an order in the market after allocating to each brand (for example, in the case of FIGS. 16 to 19), when the purchase order data with a new priority is received, it is already received by the execution preparation processing means. Among the selling order data stored in the selling order storage means, the selling order quantity of the selling order data for each priority brand designated by the received new buying order data with priority is acquired. Using the sell order quantity of the acquired sell order data, the new priority order that was accepted so that the sell order quantity corresponds to the issue of each priority order, that is, the contract is executed. The purchase order quantity of the data is allocated to each priority brand according to the priority, and the purchase order data of each brand in which the purchase order quantity is allocated to each priority brand is stored in the purchase order storage means. Then, the transaction execution processing means performs a sales transaction process with the sales order data already received and stored in the sales order storage means (see FIG. 17). On the other hand, when new selling order data is received, the brand of the buying order data that has already been received and stored in the buying order storage means is the reference brand (buying order data with new priority order). This is because the purchase order data of the reference issue remains after a series of processes when the purchase order is received.), The issue of the purchase order data stored in the storage means for purchase order is determined according to the priority order. , New selling order data stored in the storage means for selling orders, and purchase orders in which the stocks are replaced while sequentially replacing from the base stocks to the alternative stocks or from the alternative stocks to the alternative stocks of the next priority Transaction transaction processing with data is performed (see FIG. 18). As a result, it is possible to satisfy the customer's transaction desire indicated by the priority order purchase order when receiving a priority order purchase order or when receiving a normal order without priority order. As well as being possible, it is possible to increase the liquidity of securities by increasing the possibility of closing sales orders.

  Further, in the securities trading processing system described above, the buy order is a buy order with priority, and the sell order is a normal sell order without priority. The selling order may be a selling order with a priority order, and the buying order may be a normal buying order without a priority order. Even when the trading is reversed in this way, the above-described buying order has a priority order. The same effect as the case of making a purchase order can be obtained.

That is, in the securities trading system described above,
The execution preparation processing means is
When the trade classification of the order data received by the order acceptance processing means is information indicating sale,
The purchase order of each execution target purchase order data stored in the purchase order storage means in association with the same brand identification information as the brand identification information about the reference brand and the alternative brand of the received order data Obtaining the quantity, calculating the total quantity K of the purchase order quantity of the acquired purchase order data of each execution target, comparing the received order quantity U of the received order data with the total quantity K of the purchase order quantity,
If the total quantity K of the buy order quantity is greater than or equal to the sell order quantity U,
The execution target including the customer identification information, the brand identification information for the reference brand of the first priority, and the order quantity consisting of the smaller one of the selling order quantity U and the purchase order quantity K1 of the standard brand. Selling order data is stored in the selling order storage means in association with the order identification information,
When the sell order quantity U is larger than the buy order quantity K1 of the reference issue, the quantity (U−K1) obtained by subtracting the buy order quantity K1 of the reference issue of the first priority from the sell order quantity U is According to the priority order, the sales order quantity of the alternative brands below the second priority is allocated, the customer identification information, each brand identification information about the alternative brands below the second priority, and each distributed sales order The selling order data of each execution target including quantity is stored in the selling order storage means in association with the order identification information,
If the total quantity K of the buy order quantity is less than the sell order quantity U,
A quantity (U-KT) obtained by subtracting the total quantity KT of the purchase order quantities of the alternative brands below the second priority from the customer identification information, the brand identification information about the reference brand of the first priority, and the sell order quantity U The sales order data to be executed including the order quantity consisting of :) and stored in the sales order storage means in association with the order identification information;
The total quantity KT of the purchase order quantities of the alternative issues below the second priority is distributed as the sell order quantities of the alternative issues below the second priority according to the priority, and the customer identification information, the second priority A process of storing each item identification information about the following alternative item and each selling target selling order data including each distributed selling order quantity in the selling order storage unit in association with the order identification information. Run,
When the trade classification of the order data received by the order acceptance processing means is information indicating purchase,
The execution order purchase order data including the customer identification information, the brand identification information about the securities to be purchased, and the order quantity is stored in the purchase order storage unit in association with the order identification information. It is configured to execute processing,
The transaction execution processing means is:
It consists of transaction execution processing means at the time of selling order reception and transaction execution processing means at the time of purchase order reception,
The transaction execution processing means at the time of accepting a selling order is:
Each time new execution target sell order data is stored in the sell order storage means by the execution preparation processing means, it is stored in the sell order storage means as the order quantity of the new execution target sell order data. In addition, the selling order quantity of the reference issue and the selling order quantity of the alternative issue, and the issue identification information about the reference issue and the issue identification information about the alternative issue included in these new execution target sale order data, respectively. The purchase order quantity associated with the same brand identification information and stored in the buy order storage means as the order quantity of the purchase order data to be executed is matched, and the sell order quantity and purchase price for these same brands are matched. Executes the process of determining the amount that the order quantity corresponds to as a constant quantity for sell and buy orders,
The transaction execution processing means at the time of purchase order reception is:

With regard to buy order data or sell order data subject to execution, which is determined as a contract amount, and the entire quantity of the buy order quantity or the sell order quantity is executed, the execution flag is set to “completed” or “closed”. For the purchase order data or sell order data to be executed with the purchase order quantity or part of the sell order quantity being executed, the purchase order stored in the purchase order storage means is updated. Executing a first order transaction process for updating the buy order quantity or the sell order quantity by subtracting the constant quantity from the sell order quantity stored in the quantity or the sell order storage means;
After the first sales transaction processing, if there is the selling order data to be executed stored in the selling order storage means in association with the contract flag set to indicate the unsettled state, the execution The brand identification information about the alternative brand stored in the order data storage means in association with the same order identification information as the order identification information stored in the purchase order storage means for the target purchase order data, and Using the priority order, in accordance with the priority order, the brand identification information stored in the purchase order storage means for the purchase order data to be executed is replaced with the brand identification information for the alternative brand from the reference brand. The stock replacement process is executed for all the execution target purchase order data associated with the execution flag that is in a state indicating unsettled, or Is stored in the selling order storage means with respect to the selling order data of the execution target associated with the execution flag in which the brand identification information about the alternative brand after replacement is in a state indicating unsettled After executing only the buy order data subject to execution, which is the same brand identification information as the brand identification information, the sell order quantity stored as the remaining order quantity of the sell order data subject to execution is stored in the sell order storage unit; The alternative stored in the purchase order storage means in association with the same brand identification information as the brand identification information included in the execution target sell order data, as the remaining order quantity of the execution target buy order data Match the purchase order quantity of the brand in the order of the reception order management information indicating the early reception order, and the quantity corresponding to the purchase order quantity and the sell order quantity for these same brands For the execution order buy / sell data, which is determined as the contract quantity of the buy / sell order and the contract quantity of the buy / sell order quantity or the total quantity of the sell order quantity is fulfilled, the execution flag is filled from unfilled The purchase order data or the sell order data to be executed, in which the purchase order quantity or a part of the sell order quantity is executed, is updated to the state indicating the purchase order quantity, and the purchase order stored in the purchase order storage means Executing a secondary sales transaction process of subtracting the approximate constant amount from the order quantity or the sell order quantity stored in the sell order storage means to update the buy order quantity or the sell order quantity;
Further, after each sales transaction processing after the second sales transaction processing, the execution target sell order data stored in the sell order storage means in association with the contract flag in a state indicating unsettled. And there is a designation of an alternative brand of the next rank in the execution order buy order data, the brand identification information stored in the buy order storage means for the execution order buy order data is , A stock replacement process for replacing the stock identification information for the alternative stock of the next priority, a sell order quantity stored as a remaining order quantity of the sell order data to be executed in the sell order storage means, and Corresponding to the same brand identification information as the brand identification information included in the sell order data to be executed, stored in the buy order storage means as the remaining order quantity of the buy order data to be executed Further, the purchase order quantity of the alternative brand of the next priority is matched in the order of the reception order management information indicating the early reception order, and the purchase order quantity and the sell order quantity for these same brands correspond to each other. For the buy order data or sell order data subject to execution in which the minutes are determined as the contract amount of the buy order and the sell order, and the total quantity of the buy order quantity or the sell order quantity is executed, the execution flag is set from uncommitted. The purchase order data or the sell order data to be executed, which is updated to a state indicating a contracted execution, and a part of the buy order quantity or the sell order quantity is executed, is stored in the buy order storage means. A third sales transaction process for updating the buy order quantity or the sell order quantity by subtracting the approximate constant quantity from the sell order quantity stored in the buy order quantity or the sell order storage means. Repeatedly executes the subsequent sale transaction processing,
After the final sales transaction processing using the purchase order quantity of the alternative issue with the lowest priority order, it is stored in the purchase order storage means in association with the execution flag that is in a state indicating unsettled. When there is buy order data to be executed, the stock replacement that returns the brand identification information stored in the buy order storage means for the buy order data to be executed to the brand identification information for the reference brand It is desirable to have a configuration for executing processing.

  In this way, when the contract processing using the reception order management information is performed, it is possible to realize the time priority principle that the order data of the customer who has previously ordered is preferentially executed. Therefore, when a buy order of the same brand or a sell order of the same brand competes, the customer who has made a purchase order or a sell order first has priority. In addition, when new purchase order data is received, if the purchase order quantity that has not been promised for the purchase order data received before then remains in the purchase order storage means as the purchase order quantity of the standard issue However, since there is no corresponding sales order quantity of the same issue, there is virtually no competition between those purchase orders, but the purchase order quantity for each new purchase order data is assigned to each priority. If there is a remaining order quantity after a series of purchases and purchases that have been allocated to the stocks and placed on the market, the new stock of the purchase order data and the base stock of the purchase order data received before that If they match, then when new selling order data is accepted, these buying orders will compete and the previously accepted buying order will be preferentially executed. Further, when new selling order data is received, the stocks of the buy order are sequentially replaced in the order of the first priority standard issue, the second priority alternative issue, the next priority alternative issue, and so on. However, for buy orders, the time-priority principle is applied when the same-priority issues match, and even if each other's issues match, If the priorities of the brands are different, the purchase order with the brand as a high priority brand is preferentially executed regardless of the order reception time. For example, the purchase order data of the customer A that has been previously ordered has the brand Y as the alternative brand of the second priority (the customer A's buy order data is used for the buy order as the buy order of the brand X as the base brand. The purchase order data of the customer B ordered later has the brand Y as the reference brand of the first priority (the customer B buy order data is the reference brand). It remains in the buy order storage means as a purchase order for the brand Y.) When new sell order data for the brand Y is received, the purchase order data for the customer B is received later. Since the reference stock has the first priority order, the purchase order data of the customer B is preferentially executed for the competing stock Y.

  Further, in the securities trading processing system described above, the buy order is a buy order with priority, and the sell order is a normal sell order without priority. The selling order may be a selling order with a priority order, and the buying order may be a normal buying order without a priority order. Even when the trading is reversed in this way, the above-described buying order has a priority order. The same effect as the case of making a purchase order can be obtained.

That is, in the securities trading system described above,

The transfer processing database 35 and the customer account database 36 are provided.

  This government bond trading system 10 forms a PTS market for buying and selling individual government bonds (a trading market using a private trading system, that is, a computer network market established by a financial institution such as a securities company). Has been.

  The government bond trading system 10 is connected to a terminal device 40 operated by a customer who inputs an order or an input agent (such as a salesperson or an operator) via the network 1 which is a communication line. Here, the network 1 includes, for example, various types such as the Internet, an intranet, an extranet, a LAN, a MAN, a WAN, or a combination thereof, and is wired or wireless, or even wired. Regardless of whether the type is a mixed type of radio, in short, it may be anything that can transmit information at a certain speed between a plurality of points (regardless of the length of the distance).

  The processing unit 20 includes an order reception processing unit 21, an execution preparation processing unit 22, a transaction execution processing unit 23, and a transfer processing unit 24.

  The order reception processing means 21 transmits display data for the order screen 100 (see FIG. 10) to the terminal device 40 via the network 1 in response to a request from the customer or its input agent, and also the customer or its input agent. The customer order data input by the user using the order screen 100 and transmitted from the terminal device 40 via the network 1 is received, order identification information (order number) is automatically given to the received order data, and the order is received. A process of storing the data in the order data storage means 30 (see FIG. 2) in association with the order identification information is executed.

  Here, when the order data received by the order reception processing means 21 is sell order data, the customer identification information, the brand identification information about the individual government bonds that are the securities to be sold, The purchase / sale category shown (the sale / sale category because it is a sale order) and the order value (sale order value) of the government bonds for individuals, which is the order quantity (sell order quantity), are included. On the other hand, in the case of purchase order data, there are the following three forms according to the selection of the input method on the order screen 100 of FIG. 10 by the customer.

  In the purchase order data of the first form, customer identification information, brand identification information about a standard issue among individual government bonds that are securities to be purchased, and a standard when a trading transaction of the standard issue is not established Stock identification information on alternative stocks to be purchased in place of stocks, priorities that determine the order of purchase of individual government bonds that are securities to be purchased, and trading categories that indicate the type of trading ( Since it is a buy order, it includes a purchase / sale category, which is information indicating purchase), and an order face value (buy order face value) of an individual government bond that is an order quantity (buy order quantity). As for the priority, data indicating the priority (for example, “1” for the first priority, “2” for the second priority, “3” for the third priority). Etc.), it is possible to specify the priority order of each brand by transmitting and receiving the brand identification information for the brands of each priority in the same order as the priority. The purchase order data in the first form is input data when the customer selects and inputs the first designation method on the order screen 100 in FIG.

  The purchase order data in the second form includes customer identification information, issue identification information about the basic issue of individual government bonds that are the securities to be purchased, and condition instructions for determining alternative issues with priorities. Data, trading category (buy order because it is a buy order, trading category), and the order amount (buy order amount) of the order amount (buy order amount) Is included. Further, when the order acceptance processing means 21 receives the purchase order data of the second form, the order acceptance processing means 21 uses the brand identification information and the condition instruction data for the reference brand included in the received buy order data. The order data is associated with the order identification information in a state in which the stock identification information and priority for the determined alternative stock are added to the received purchase order data. The process memorize | stored in the memory | storage means 30 (refer FIG. 2) is performed. At this time, the order reception processing means 21 may determine the alternative issues together with the priority order by an algorithm described in the program, or the data stored in the government bond database 32 (see FIG. 3) as necessary. Used to determine alternatives along with priorities. The purchase order data in the second form is input data when the customer selects and inputs the second designation method on the order screen 100 in FIG.

  In the purchase order data of the third form, customer identification information, condition instruction data for setting a standard issue and an alternative issue for a personal bond that is a securities to be purchased, together with priorities, The purchase / sale category indicated (the purchase / sale category as information indicating purchase because it is a buy order) and the order amount (buy order amount) of the government bonds for individuals as the order quantity (buy order quantity) are included. Further, when receiving the purchase order data of the third form, the order reception processing means 21 determines the reference brand and the alternative brand together with the priority order using the condition instruction data included in the received buy order data. In order to store the order data in association with the order identification information in the state in which the stock identification information about the determined base stock and the alternative stock and the priority order are added to the received purchase order data. The process memorize | stored in the means 30 (refer FIG. 2) is performed. At this time, the order reception processing means 21 may determine the reference issue and the alternative issue together with the priority order by an algorithm described in the program, or is stored in the government bond database 32 (see FIG. 3) as necessary. The reference stock and the alternative stock may be determined together with the priority order using the data. The purchase order data in the third form is input data when the customer selects and inputs the third designation method on the order screen 100 in FIG.

  The execution preparation processing means 22 accepts the order data received by the order reception processing means 21 and receives order management information for preferentially executing the order of the customer previously ordered (a common reception order for buy orders and sell orders). Order management information, or purchase order single and sell order single reception order management information), and the order data received and received by the order reception processing means 21 is information indicating purchase. Execution target including customer identification information, issue identification information on the basic issue of individual government bonds that are securities to be purchased, buying and selling classifications indicating purchase, and purchase order face value (buy order quantity) The purchase order data is stored in the purchase order storage means 33 (see FIG. 4) in association with the order identification information, the execution flag indicating the unsettled status, and the reception order management information. If the order classification received by the order acceptance processing means 21 is information indicating sale, customer identification information, brand identification information about individual government bonds that are securities to be sold, information indicating sale The sales order data to be executed including the sales category and the sales order face value (sell order quantity) are associated with the order identification information, the execution flag indicating unsettled status, and the reception order management information. The processing to be stored in the sales order storage means 34 (see FIG. 5) is executed.

  The transaction execution processing means 23 are identical to each other at least once in a day on a predetermined processing time (for example, every hour between 9:30 am and 5:30 pm). The purchase order face value (buy order quantity) of the reference brand stored as the order face value (order quantity) of the purchase order data to be executed in the purchase order storage means 33 (see FIG. 4) in association with the stock identification information of ) And the selling order face value (selling order quantity) stored as the order quantity of the selling order data to be executed in the selling order storage means 34 (see FIG. 5), and buy orders for these same brands The amount corresponding to the face value (buy order quantity) and the sell order face value (sell order quantity) is determined as the contract face value (approx. Constant amount) of the buy and sell orders. Not enough to buy) Of the remaining order face value (remaining order quantity) is stored in the purchase order storage means 33 (see FIG. 4) according to the priority order stored in the order data storage means 30 (see FIG. 2). In the state where the brand identification information of the purchase order data to be executed is sequentially replaced with the brand identification information on the alternative brands of the next priority, the purchase order storage means 33 (see FIG. 4) in the purchase order face value (buy order quantity) of the alternative brand stored as the remaining order face value (remaining order quantity) of the purchase order data to be executed and the sales order storage means 34 (see FIG. 5). The sales order face value (sell order quantity) stored as the remaining order face value (remaining order quantity) in the sales order data subject to execution is matched, and the purchase order face value (buy order quantity) for these same brands Sell order amount Amount (sales order quantity) and is repeating the process for determining as commitments par value of minute buy orders and sell orders that are compatible (contract quantity) is intended to run. Note that changes such as replacement and return of the brand identification information may be changed by rewriting the brand identification information in the storage means.

  Further, the transaction execution processing unit 23 stores the determined purchase face value (a fixed amount) of the purchase order in the purchase order storage unit 33 (see FIG. 4) for the purchase order data to be executed. Corresponding to identification information, stock identification information about the stock executed in the standard stock or alternative stock, order identification information, buy / sell classification indicated as buying information, and transfer flag set as non-transferring status The transfer processing database 35 (see FIG. 6) stores the purchase order as contract data, and the sales order storage means 34 for the execution target sell order data for which the contracted denomination (a fixed amount) of the determined sell order is executed. (See FIG. 5) The customer identification information, brand identification information, order identification information stored in (refer to FIG. 5), and the buying / selling classification as information indicating selling, and the state indicating untransferred Transfer flag transfer process database 35 as commitments data order sales in association with performing the process of storing (see FIG. 6).

  The execution processing by the transaction execution processing means 23 by matching the purchase order face value (buy order quantity) and the sell order face value (sell order quantity) is stored in the purchase order storage means 33 (see FIG. 4). Since the purchase order face value (buy order quantity) and the sell order face value (sell order quantity) stored in the sales order storage means 34 (see FIG. 5) are used, the government bond trading processing system 10 Storing the order data in the purchase order storage means 33 or the sell order storage means 34 corresponds to the order processing for the purchase order or the sell order in the PTS market.

  More specifically, the transaction execution processing unit 23 executes at least one predetermined processing time in a day (for example, every hour between 9:30 am and 5:30 pm, etc. ), The purchase order face value (buy order) of the reference brand stored in the buying order storage means 33 (see FIG. 4) in association with the same brand identification information and the execution flag indicating the unsettled state. Quantity) and the sales order face value (sale order quantity) stored in the sales order storage means 34 (see FIG. 5) are matched in the order of reception order management information indicating the early reception order, and the same brand The purchase amount and the purchase order's nominal amount (approx. Constant amount) are determined as the purchase order's nominal amount (buy order quantity) and sell order's nominal amount (sell order quantity) correspond to each other. Purchase order quantity) or sell order value For the purchase order data or sell order data subject to execution for which the full face value (total quantity) of the amount (sell order quantity) has been executed, the execution flag is updated from unfilled to filled state, and the buy order face value For purchase order data or sell order data to be executed with a part of face value (partial quantity) of (buy order quantity) or sell order face value (sell order quantity), the purchase order storage means 33 A contract face amount (approximately constant amount) from a purchase order face amount (buy order quantity) stored in (see FIG. 4) or a sell order face amount (sell order quantity) stored in the sell order storage means 34 (see FIG. 5). ) Is subtracted to update the purchase order face value (buy order quantity) or the sell order face value (sell order quantity).

  Further, the transaction execution processing unit 23 stores the execution target stored in the purchase order storage unit 33 (see FIG. 4) in association with the execution flag set in the state indicating the unsettled state after the first sales transaction processing. If there is purchase order data, the order data storage means associated with the same order identification information as the order identification information stored in the purchase order storage means 33 (see FIG. 4) for the execution order purchase order data. Acquires stock identification information for the alternative stock of the second priority from the stock identification information and priority for the alternative stock stored in 30 (refer to FIG. 2), and corresponds to the execution flag indicating the status of uncommitted A brand replacement process is performed to replace the brand identification information attached to the purchase order storage means 33 (see FIG. 4) from the brand identification information for the base brand to the brand identification information for the alternative brand. After that, the purchase order face value (buy order) of the alternative brand stored in the purchase order storage means 33 (see FIG. 4) in association with the same brand identification information and the contract flag indicating the unfilled state. Quantity) and the sales order face value (sale order quantity) stored in the sales order storage means 34 (see FIG. 5) are matched in the order of reception order management information indicating the early reception order, and the same brand The purchase amount and the purchase order's nominal amount (approx. Constant amount) are determined as the purchase order's nominal amount (buy order quantity) and sell order's nominal amount (sell order quantity) correspond to each other. For the purchase order data or sell order data subject to execution with the full face value (total quantity) of the purchase order quantity) or sell order face value (sell order quantity), the execution flag indicates that the execution flag has been closed to closed Update and buy For purchase order data or sell order data subject to execution with a partial face value (partial quantity) of the text face value (buy order quantity) or sell order face value (sell order quantity) The contract face amount from the purchase order face amount (buy order quantity) stored in the storage means 33 (see FIG. 4) or the sell order face amount (sell order quantity) stored in the sell order storage means 34 (see FIG. 5). The secondary sales transaction process is executed to update the purchase order face value (buy order quantity) or the sell order face value (sell order quantity) by subtracting (approximately constant amount).

  Further, the transaction execution processing means 23 is associated with the execution flag indicating the unsettled state in the purchase order storage means 33 (see FIG. 4) after each sales transaction processing after the second sales transaction processing. When there is stored purchase order data to be executed, and there is designation of alternative stocks of the next priority order (not for individual buy order data, the system accepts designation of alternative stocks of the next priority order) In this case, the brand identification information stored in the purchase order storage means 33 (see FIG. 4) for the execution order buy order data is used as the brand identification for the alternative brand of the next priority. Next, stored in the purchase order storage means 33 (see FIG. 4) in association with the brand replacement process to replace the information, and the same brand identification information and the execution flag indicating the unsettled state. Acceptance indicating the order of early acceptance of the purchase order face value (buy order quantity) of the alternative brands of priority order and the sell order face value (sell order quantity) stored in the sell order storage means 34 (see FIG. 5) Match the order of the order management information, and the amount corresponding to the purchase order face value (buy order quantity) and sell order face value (sell order quantity) for these same issues. About purchase order data or sell order data subject to execution that is determined as (a fixed amount) and the full face value (total quantity) of the purchase order face value (buy order quantity) or sell order face value (sell order quantity) is executed Updates the fill flag from unfilled to filled, and fills the face value (partial quantity) of the purchase order face value (buy order quantity) or sell order face value (sell order quantity). Purchase order date for execution Alternatively, for sell order data, the purchase order face amount (buy order quantity) stored in the buy order storage means 33 (see FIG. 4) or the sell order face amount stored in the sell order storage means 34 (see FIG. 5). Trading transaction after the third trading transaction that subtracts the contracted face value (approximately constant amount) from the amount (sell order quantity) and updates the purchase order face value (buy order quantity) or sell order face value (sell order quantity) Repeat the process.

  In the present embodiment, as an example, as shown in the order screen 100 of FIG. 10, it is possible to specify up to the alternative stocks of the third priority order, so that the purchase order storage means 33 (FIG. 4). Corresponding to the stock replacement process that replaces the stock identification information stored in the reference) with the stock identification information for the alternative stock of the 3rd priority, and the execution flag that is set to indicate the same stock identification information and uncommitted The purchase order face value (buy order quantity) of the alternative brands of the third priority ranking stored in the buy order storage means 33 (see FIG. 4) and stored in the sell order storage means 34 (see FIG. 5). The sales order face value (sale order quantity) is matched with the order of reception order management information indicating the early reception order, and the process up to the third sales transaction processing for determining the contract face amount (about constant amount) is executed.

  Then, the transaction execution processing unit 23 performs the final sales transaction processing using the purchase order face value (buy order quantity) of the alternative issue with the lowest priority (in this embodiment, as an example, the third priority The purchase order storage means 33 is associated with the execution flag indicating the unsettled state, after the third sale transaction processing using the purchase order face value (buy order quantity) of the alternative brand If there is execution target buy order data stored in (see FIG. 4), the brand identification information stored in the purchase order storage means 33 (see FIG. 4) for the execution target buy order data is used as a reference. The brand replacement process for returning to the brand identification information about the brand is executed.

It has been. The data of the designated period S input by the designated period input unit 150 and the data indicating which of the selection units 151 to 162 has been selected are condition instruction data. In addition, the conditions (9) to (20) listed here are only examples, and in short, the condition instruction data here is based on the data of the specified period S and the data of the specified period S. And the combination with the selection information of the algorithm which determines the alternative brand below the 2nd priority is sufficient. Further, although the illustration in FIG. 10 is omitted, the condition instruction data is based on the data of the upper limit designation period H, the data of the lower limit designation period L, and the data of the upper limit designation period H and the lower limit designation period L. It may be combined with selection information of an algorithm that determines a brand and an alternative brand of the second priority or lower.

  Further, the order screen 100 is provided with a “Send” button 170 for sending the input data to the government bond trading processing system 10.

  In the order screen 100 of FIG. 10, when the customer or its input agent performs necessary input or selection and clicks the “Send” button 170, the order data is sent from the terminal device 40 via the network 1 to the government bond trading processing system 10. Sent to.

  At this time, in the case of a sell order, the order data to be transmitted includes customer identification information, brand identification information about personal government bonds, which are securities to be sold, and information indicating sale. A classification and a face value of a sales order (a sales order quantity) are included.

  In addition, in the order data to be transmitted, if the customer has specified the order symbol by the first specification method in the purchase order (in the case of the purchase order data in the first form), the customer identification information and the reference Each brand identification information for the brand and two alternative brands, the priority of each brand, the trading category as information indicating buying, and the purchase order face value (buy order quantity) are included.

  Further, in the order data to be transmitted, if the customer designates the order issue by the second designation method in the purchase order (in the case of the purchase order data in the second form), the customer identification information, the standard Brand identification information on the brand, condition instruction data for selecting alternative brands together with priority (selection information on which one of the selection units 141 to 148 has been selected), and a trade classification that is information indicating buying, The purchase order face value (buy order quantity) is included.

  In addition, in the order data to be transmitted, if the customer designates the order issue by the third designation method in the purchase order (in the case of the purchase order data in the third form), the customer identification information, the reference Condition instruction data (designated period S data and selection information indicating which one of the selection units 151 to 162 has been selected) for determining a brand and two alternative brands together with priorities, and buying and selling as information indicating buying The category and the purchase order face value (buy order quantity) are included.

  Note that the customer identification information (in the present embodiment, an account number is used as an example) is input by the customer or its input agent at an appropriate stage before the input operation on the order screen 100.

  In the government bond trading processing system 10, when the order reception processing means 21 receives the order data transmitted from the terminal device 40, the order identification information (order number) is automatically given to the received order data, and the received order data is Then, it is stored in the order data storage means 30 (see FIG. 2) in association with the automatically assigned order identification information (order number) (step S2 in FIG. 8).

  At this time, when the purchase order data of the second form is received, the order reception processing means 21 performs the brand identification information and the condition instruction data (reference selection units 141 to 141) for the reference brand included in the received buy order data. 148), the alternative stocks of the second and third priority orders are determined, and the stock identification information and the priority order of the determined alternative stocks are added to the received buy order data. In this state, the purchase order data is stored in the order data storage means 30 (see FIG. 2) in association with the order identification information. For example, as in the example of FIG. 10, if the reference issue is the 17th bond and the condition (1) of the selection unit 141 is selected, the condition (1) described in the program is changed. According to the algorithm for execution, the second priority alternative issue is determined to be the 18th bond, and the third priority alternative issue is the 19th bond. As in the example of information = “T0001”, buy order data is stored in the order data storage means 30 (see FIG. 2). Whether or not there are 18th and 19th bonds as alternatives in accordance with the condition of (1) for the 17th bond, which is the standard issue designated by the customer, is determined by the JGB database 32 (Fig. 3), or when the program is updated each time a new issue of JGB is issued, it may be determined from the description data in the program.

  In addition, when the purchase order data of the third form is received, the order reception processing means 21 causes the condition instruction data included in the received purchase order data (the data of the designated period S and the selection units 151 to 162). Using the selection information on which one is selected), the first priority standard issue, the second priority alternative issue, and the third priority alternative issue are determined, and the determined reference issue and the two alternative issues are determined. The purchase order data is stored in the order data storage means 30 (see FIG. 2) in association with the order identification information in a state in which the brand identification information and the priority order are added to the received purchase order data. More specifically, by adding data (for example, 5 years) of the specified period S to the current date (for example, February 15, 2009) acquired from the system, a date (for example, a boundary of judgment) (February 15, 2014) is calculated, and the date that becomes the boundary of this judgment is compared with the redemption date stored in the JGB database 32 (see FIG. 3). Stocks that satisfy the condition that the remaining period until the redemption date is less than or equal to the specified period S (or satisfies this condition) The odd-numbered issues and even-numbered issues) are extracted, and the issues of each priority order are determined from the extracted issues according to the conditions of the longest or shortest remaining period.

  Subsequently, the execution preparation processing means 22 gives priority to the order of the customer previously ordered over the order data received by the order reception processing means 21 and stored in the order data storage means 30 (see FIG. 2). Receive order management information is automatically added to make a contract. The reception order management information may be reception order management information common to a buy order and a sell order, or may be reception order management information of a buy order alone and a sell order alone. In this embodiment, as an example, FIG. 4 and FIG. As shown in FIG. 5, the reception order management information is common to buy orders and sell orders. The reception order management information is automatically given by increasing the numerical value by 1 or decreasing the numerical value by 1, for example (in the examples of FIGS. 4 and 5, one by one). The numerical value is increased.) How much is assigned or what is assigned next may be stored in the latest reception order storage means (not shown).

  Then, the execution preparation processing means 22 refers to the order classification of the order data received by the order reception processing means 21 and stored in the order data storage means 30 (see FIG. 2) (step S3 in FIG. 8). Is the customer identification information included in the order data received by the order reception processing means 21 and stored in the order data storage means 30 (see FIG. 2), by the execution preparation processing means 22 Order identification information including stock identification information on the standard stock of the securities to be purchased, purchase / buy data subject to execution, including purchase / buy value and purchase order face value (buy order quantity). The purchase order storage means 33 (see FIG. 4) is stored in association with the execution flag indicating the unsettled state and the acceptance order management information (step S4 in FIG. 8). For example, the purchase order data illustrated in FIG. 2 is stored in the state illustrated in FIG.

  On the other hand, when the trade classification is information indicating sale, it is included in the order data received by the order acceptance processing means 21 and stored in the order data storage means 30 (see FIG. 2) by the execution preparation processing means 22. Order identification information, including customer identification information, stock identification information about securities to be sold, sales classification data indicating sales, and sales order data to be executed including the face value (sell order quantity). The sales order storage means 34 (see FIG. 5) is stored in association with the execution flag indicating the unsettled state and the acceptance order management information (step S5 in FIG. 8). For example, the sell order data illustrated in FIG. 2 is stored in the state illustrated in FIG.

  Thereafter, the transaction execution processing means 23 determines whether or not a predetermined contract processing time (for example, every hour between 9:30 am and 5:30 pm) has been reached (FIG. 8). Step S6).

  Here, when it is determined that the predetermined contract processing time has come, the transaction execution processing means 23 associates with the same brand identification information and the contract flag indicating the unsettled state, and stores the purchase order. The purchase price face amount (buy order quantity) of the reference stock stored in the means 33 (see FIG. 4), and the sell order face value (sell order quantity) stored in the sell order storage means 34 (see FIG. 5) Are matched in the order of reception order management information indicating the early reception order, and the purchase order face amount (buy order quantity) and sell order face amount (sell order quantity) corresponding to these same issues are purchased. The contract amount of the order and the sell order (contract amount) is determined, and the contract data of the buy order including the contract amount (contract amount) of the determined buy order and the contract amount of the determined sell order (contract amount) About sell orders including The data to be stored in the in correspondence with transfer flag is a state indicating non-transfer transfer process database 35 (see FIG. 6). Then, the transaction execution processing means 23 executes the purchase order data or sell order data to be executed with the full face value (total quantity) of the purchase order face value (buy order quantity) or the sell order face value (sell order quantity). For, the contract flag is updated from unfilled to state filled, and the face value (partial quantity) of the purchase order face value (buy order quantity) or sell order face value (sell order quantity) is updated. For the execution target buy order data or sell order data, the purchase order face amount (buy order quantity) stored in the buy order storage means 33 (see FIG. 4) or the sell order storage means 34 (FIG. 5). The purchase order face amount (buy order quantity) or sell order face amount (sell order quantity) is updated by subtracting the contract face amount (approximately constant quantity) from the sell order face amount (sell order quantity) stored in Primary trading office To perform (step S7 in FIG. 8).

  For example, the numerical example of FIG. 9 corresponds to the numerical examples of FIG. 2, FIG. 4, and FIG. 5, but in this example, for the issue X (17th bond), the purchase order of customer A (order identification) Information = “T0001”, acceptance order management information = “1”, 4 million yen) and purchase order of customer D (order identification information = “T0009”, acceptance order management information = “9”, 2 million yen) Designated as (first priority issue). On the other hand, the selling order of the brand X (the 17th bond) is only the selling order of the customer E (order identification information = “T0002”, reception order management information = “2”, 2 million yen). Accordingly, since the purchase order 6 million yen and the sell order 2 million yen correspond to 2 million yen, the purchase order management information is included in the purchase orders of the customers A and D. 2 million yen, which is part of the purchase order of 4 million yen of customer A, which is in the early order, is executed. On the other hand, regarding the sales order, the entire sales order of customer E of 2 million yen is executed. The remaining 2 million yen of the 4 million yen purchase order of customer A and the entire 2 million yen purchase order of customer D will remain uncommitted. On the other hand, there is no uncommitted portion left in the sell order.

  For the issue Y (18th bond), specified as the reference issue (first priority issue) in the purchase order of customer B (order identification information = "T0004", acceptance order management information = "4", 5 million yen) Has been. On the other hand, the selling order of the brand Y (18th bond) includes the selling order of the customer F (order identification information = “T0003”, reception order management information = “3”, 3 million yen), and the selling order of the customer G ( Order identification information = “T0005”, acceptance order management information = “5”, 4 million yen) and sales order of customer H (order identification information = “T0006”, acceptance order management information = “6”, 2 million yen) There is. Accordingly, the portion corresponding to the purchase order of 5 million yen and the sell order of 9 million yen is 5 million yen, and the purchase order for the customer B is all 5 million yen for the purchase order. On the other hand, regarding the sales orders, among the sales orders of the customers F, G, and H, all of the sales orders 3 million yen of the customer F whose reception order management information is in order, and the sales order 4 million yen of the customer G 2 million yen, which is a part of the contract, will be executed. The remaining 2 million yen of the sales order 4 million yen of customer G and the entire sales order 2 million yen of customer H remain uncommitted. On the other hand, no uncommitted portion remains in the buy order.

  For issue Z (19th bond), designated as the reference issue (first priority issue) in customer C's buy order (order identification information = "T0007", acceptance order management information = "7", 3 million yen) Has been. On the other hand, the selling order of the brand Z (19th bond) includes the selling order of the customer J (order identification information = “T0008”, reception order management information = “8”, 1 million yen) and the selling order of the customer K ( Order identification information = “T0010”, reception order management information = “10”, 1 million yen). Therefore, since the portion corresponding to the purchase order of 3 million yen and the sell order of 2 million yen is 2 million yen, the purchase order is a part of the purchase order of 3 million yen of the customer C. 2 million yen will be executed. On the other hand, regarding the sales order, all of the sales order of customer J of 1 million yen and all of the sales order of customer K of 1 million yen are executed. Then, 1 million yen, which is the remaining part of the 3 million yen purchase order of customer C, remains as an uncommitted portion. On the other hand, there is no uncommitted portion left in the sell order.

  Subsequently, in the present embodiment, since the purchase order is designated up to the third priority issue (that is, the second priority issue is designated), the transaction execution processing means 23 performs the primary order. If there is purchase order data to be executed that is stored in the purchase order storage means 33 (see FIG. 4) in association with the execution flag that indicates an unsettled state after the sales transaction processing, The substitute brand stored in the order data storage means 30 (see FIG. 2) in association with the same order identification information as the order identification information stored in the purchase order storage means 33 (see FIG. 4). The stock identification information about the alternative stock of the second priority order is acquired from the stock identification information and the priority order for the, and the purchase order storage means 33 (FIG. 4) is associated with the contract flag set to indicate the unfilled state. reference Stock identification information stored in the, from brand identity for the reference stock executes stocks substitution process to replace to stock identification information about the alternative brand second priority (step S8 in FIG. 8).

  For example, in the numerical example of FIG. 9 described above (corresponding to the numerical examples of FIG. 2, FIG. 4, and FIG. 5), the purchase orders of customers A, B, C, and D after the first sales transaction processing Of these, the uncommitted portion remains in the purchase orders of the customers A, C, and D, so the purchase order of the customer A is the second from the issue X (17th bond) that is the reference issue of the first priority. Replaced with issue Y (18th bond), which is an alternative issue of priority order, and for purchase order of customer C, from issue Z (19th bond), which is the reference issue of first priority, Replacement for the issue Y (18th bond), which is the alternative issue, and for the purchase order of customer D, from the issue X (17th bond), which is the first priority reference issue, to the second priority alternative issue Replaced with a brand Z (19th bond).

  Thereafter, the second priority order stored in the purchase order storage means 33 (see FIG. 4) in association with the same brand identification information and the execution flag indicating the unsettled state by the transaction execution processing means 23. The order-of-reception management indicating the order of early acceptance of the purchase order face amount (buy order quantity) of the alternative brands and the sell order face amount (sell order quantity) stored in the storage means 34 for sale order (see FIG. 5) Matching the order of information, the amount corresponding to the buy order face value (buy order quantity) and sell order face value (sell order quantity) for these same issues is the contract face value (contract) of the buy and sell orders. Quantity) and the contract data of the buy order including the contracted face value (contracted amount) of the determined buy order, and the contract data of the sell order including the contracted face value (contracted amount) of the determined sell order are not transferred. Indicates the state It was transferred flag in correspondence to be stored in the transfer process database 35 (see FIG. 6). Then, the transaction execution processing means 23 executes the purchase order data or sell order data to be executed with the full face value (total quantity) of the purchase order face value (buy order quantity) or the sell order face value (sell order quantity). For, the contract flag is updated from unfilled to state filled, and the face value (partial quantity) of the purchase order face value (buy order quantity) or sell order face value (sell order quantity) is updated. For the execution target buy order data or sell order data, the purchase order face amount (buy order quantity) stored in the buy order storage means 33 (see FIG. 4) or the sell order storage means 34 (FIG. 5). The purchase order face amount (buy order quantity) or sell order face amount (sell order quantity) is updated by subtracting the contract face amount (approximately constant quantity) from the sell order face amount (sell order quantity) stored in Secondary trading office To perform (step S9 in FIG. 8).

  For example, in the numerical example of FIG. 9 described above (corresponding to the numerical examples of FIGS. 2, 4, and 5), there is no buy order or sell order for the issue X (17th bond). The purchase order of customer B designates issue X (17th bond) as an alternative issue of the second priority, but all is executed in the first trading transaction processing in step S7, and the uncommitted portion remains. Because it is not.

  For issue Y (18th bond), customer A's purchase order (order identification information = “T0001”, acceptance order management information = “1”, remaining 2 million yen) and customer C's purchase order (order identification information = “T0007”, reception order management information = “7”, remaining 1,000,000 yen), it is designated as an alternative brand of the second priority. On the other hand, the selling order of the brand Y (18th bond) is the selling order of the customer G (order identification information = “T0005”, reception order management information = “5”, remaining 2 million yen), and the selling order of the customer H. (Order identification information = “T0006”, reception order management information = “6”, remaining 2 million yen). Therefore, since the amount corresponding to these purchase orders of 3 million yen and the sell order of 4 million yen is 3 million yen, the purchase order includes all of the purchase order of 2 million yen of customer A and the purchase of customer C. The entire order of 1 million yen is executed. On the other hand, regarding the sales order, out of the sales orders of the customers G and H, all of the sales orders of the customer G of 2 million yen and the sales order of the customer H of 2 million yen out of the order of receiving order management information. 1 million yen, which is a part of And 1 million yen which is the remaining part of the sales order 2 million yen of the customer H remains as an uncommitted portion. On the other hand, no uncommitted portion remains in the buy order.

  The issue Z (19th bond) is designated as an alternative issue of the second priority in the purchase order of customer D (order identification information = “T0009”, reception order management information = “9”, remaining 2 million yen) ing. On the other hand, there is no selling order for the issue Z (19th Bond). Accordingly, there is no commitment, and the purchase order of customer D of 2 million yen remains as an uncommitted portion.

  Subsequently, in the present embodiment, since the purchase order is designated up to the third priority issue (that is, the third priority issue is designated), the transaction execution processing means 23 executes the secondary order. If there is purchase order data to be executed that is stored in the purchase order storage means 33 (see FIG. 4) in association with the execution flag that indicates an unsettled state after the sales transaction processing, The substitute brand stored in the order data storage means 30 (see FIG. 2) in association with the same order identification information as the order identification information stored in the purchase order storage means 33 (see FIG. 4). The stock identification information on the alternative stock of the third priority order is acquired from the stock identification information and the priority order of the product, and the purchase order storage means 33 (FIG. 4) is associated with the contract flag set to indicate the unfilled state. reference 8 is executed to replace the brand identification information stored in the brand identification information for the alternative brand of the second priority with the brand identification information for the alternative brand of the third priority (step of FIG. 8). S10).

  For example, in the numerical example of FIG. 9 described above (corresponding to the numerical examples of FIG. 2, FIG. 4, and FIG. 5), after the secondary sales transaction processing, Of these, uncommitted portion remains in the purchase order of customer D, so for the purchase order of customer D, the alternative issue of the third priority from issue Z (19th Bond), which is the alternative issue of the second priority. It is replaced with the stock Y (18th bond).

  Thereafter, the third priority order stored in the purchase order storage means 33 (see FIG. 4) in association with the same brand identification information and the execution flag indicating the unsettled state by the transaction execution processing means 23. The order of receipt management that indicates the order of early receipt of the purchase order face amount (buy order quantity) of the alternative brands and the sell order face amount (sell order quantity) stored in the storage means 34 for sale order (see FIG. 5) Matching the order of information, the amount corresponding to the buy order face value (buy order quantity) and sell order face value (sell order quantity) for these same issues is the contract face value (contract) of the buy and sell orders. Quantity) and the contract data of the buy order including the contracted face value (contracted amount) of the determined buy order, and the contract data of the sell order including the contracted face value (contracted amount) of the determined sell order are not transferred. Indicates the state It was transferred flag in correspondence to be stored in the transfer process database 35 (see FIG. 6). Then, the transaction execution processing means 23 executes the purchase order data or sell order data to be executed with the full face value (total quantity) of the purchase order face value (buy order quantity) or the sell order face value (sell order quantity). For, the contract flag is updated from unfilled to filled, and the face value (partial quantity) of the purchase order face value (buy order quantity) or the sell order face value (sell order quantity) is updated. Regarding the execution target buy order data or sell order data, the purchase order face amount (buy order quantity) stored in the buy order storage means 33 (see FIG. 4) or the sell order storage means 34 (FIG. 5). The purchase order face amount (buy order quantity) or sell order face amount (sell order quantity) is updated by subtracting the contract face amount (approximately constant quantity) from the sell order face amount (sell order quantity) stored in Tertiary trading office To perform (step S11 in FIG. 8).

  For example, in the numerical example of FIG. 9 described above (corresponding to the numerical examples of FIGS. 2, 4, and 5), for the issue X (17th bond) and the issue Z (19th bond), There are no buy or sell orders.

  The issue Y (18th bond) is designated as an alternative issue of the 3rd priority in the purchase order of customer D (order identification information = “T0009”, reception order management information = “9”, remaining 2 million yen) ing. On the other hand, the selling order of the brand Y (18th bond) includes the selling order of the customer H (order identification information = “T0006”, reception order management information = “6”, remaining 1 million yen). Therefore, since the portion corresponding to the purchase order of 2 million yen and the sell order of 1 million yen is 1 million yen, the purchase order is a part of the purchase order of 2 million yen of the customer D. 1 million yen will be executed. On the other hand, regarding the sales order, the entire sales order of 1 million yen of customer H is executed. Then, 1 million yen, which is the remaining part of the purchase order 2 million yen of customer D, remains as an uncommitted portion. On the other hand, there is no uncommitted portion left in the sell order.

  Subsequently, after the third sales transaction processing, which is the final sales transaction processing, by the transaction execution processing means 23, the purchase order storage means 33 (FIG. 4) is associated with the contract flag set in a state indicating unsettled. If there is purchase order data to be executed stored in the reference), the brand identification information stored in the purchase order storage means 33 (see FIG. 4) for the execution order buy order data is used as the third priority. A brand replacement process is performed to return the brand identification information on the alternative brands to the brand identification information on the reference brand of the first priority (step S12 in FIG. 8).

  For example, in the numerical example of FIG. 9 described above (corresponding to the numerical examples of FIG. 2, FIG. 4, FIG. 5), after the third sales transaction process, Since it remains as a buy order for issue Y (18th bond), which is an alternative issue of priority, this customer D's purchase order is assigned to issue X (17th bond), which is the reference issue of 1st priority. Return to buy order.

  Thereafter, the transfer processing means 24 stores the contract data stored in the customer account database 36 using the execution data stored in the transfer processing database 35 (see FIG. 6) in association with the transfer flag in a state indicating non-transfer. The funds balance data and the securities balance data are updated, and the transfer flag of the transfer processing database 35 is changed from the untransferred state to the transferred state (step S13 in FIG. 8). Since the details of the transfer process have already been described in detail, a description thereof is omitted here.

  Then, it is determined whether or not all the contract processing times of the day have passed (step S14 in FIG. 8). If it has not elapsed, the process returns to step S2, and the order acceptance process is performed until the next execution time.

  According to such 1st Embodiment, there exist the following effects. That is, in the government bond trading processing system 10, the customer can place a purchase order by giving a priority to a plurality of issues, and when the purchase order with this priority is accepted, Matching the purchase order face value (buy order quantity) of the standard issue of 1 priority with the sell order face value (sell order quantity) of the same issue is matched, and the buy order face value (buy order quantity) of the reference issue is not If there is a commitment, the purchase order face value (buy order quantity) and the sell order of the same brand will be replaced in accordance with the priority order, with the stocks in the purchase order being replaced with alternative stocks of the second priority or lower. Since the face value (sales order quantity) is matched and executed, the customer can obtain many opportunities to purchase brands that meet the desired conditions, and can increase trading opportunities. In addition, the possibility of execution can be increased as compared with the case of the conventional buying and selling process in which only one brand to be traded is designated and ordered. In addition, from these, it is possible to revitalize trading transactions between customers (between individuals) for individual government bonds and increase the liquidity of individual government bonds, so that not only buyers but also sellers Can also have a profit.

  Further, in the first embodiment, a method of executing contract processing at a predetermined contract processing time (similar method to the so-called plate approach method) is adopted. First, the execution preparation processing means 22 performs the purchase order face value of the reference issue. Buy order data including (buy order quantity) is stored in the purchase order storage means 33 (see FIG. 4), and the purchase order stored in the purchase order storage means 33 (see FIG. 4) by the transaction execution processing means 23 The purchase order face value (buy order quantity) of the reference brand of the data is matched with the sell order face value (sell order quantity) of the sell order data stored in the selling order storage means 34 (see FIG. 5) for the same brand. Next, when an unsettled portion occurs in the purchase order face value (buy order quantity), the buy execution order stored in the purchase order storage means 33 (see FIG. 4) by the transaction execution processing means 23 Data brands according to priority The purchase order storage means 33 (see FIG. 4) while replacing the first priority standard issue with the second priority alternative issue or the second priority alternative issue with the third priority alternative issue. The purchase order face value (buy order quantity) of the alternative brand stored in the purchase order data and the sell order face value (sell price) of the sell order data stored in the sales order storage means 34 (see FIG. 5) for the same brand. (Order quantity) to match. Then, after the third sales transaction process using the purchase order face value (buy order quantity) of the alternative priority stock with the lowest priority, the unfilled purchase order face value (buy order quantity). When a minute occurs, the transaction execution processing unit 23 returns the brand of the purchase order data stored in the purchase order storage unit 33 (see FIG. 4) to the standard brand and is executed at the next contract processing time. Since it is prepared for execution, it is possible to satisfy the customer's transaction desires indicated by each priority order even in the situation where there are multiple priority orders and multiple sales orders. it can.

  Furthermore, in the first embodiment, the transaction execution processing means 23 executes the contract processing using the reception order management information, thereby realizing the time priority principle that the order data of the customer who has previously ordered is preferentially executed. can do. Therefore, when a buy order of the same brand or a sell order of the same brand competes, it is possible to give priority to a customer who has previously made a buy order or a sell order.

The transaction execution processing means 23A (not shown) of the transaction execution processing means 23 performs a first trading transaction process, a brand replacement process after the first trading transaction process, as shown in FIG. The next sale transaction process, the brand replacement process after the second sale transaction process, the third sale transaction process, and the brand replacement process after the third sale transaction process are executed (step S25 in FIG. 11).

  In FIG. 12, the purchase order face value of the reference brand of the new purchase target purchase order data stored in the purchase order storage means 33 (see FIG. 4) by the buy order acceptance transaction execution processing means 23 </ b> A (not shown). (Buy order quantity) and the same brand identification information as the brand identification information for the standard brand included in the new execution target buy order data are stored in the selling order storage means 34 (see FIG. 5). The sales order face value (sell order quantity) of the executed sales order data to be executed is matched with the order of reception order management information indicating the order of early reception, and the purchase order face value (buy order quantity) for these same issues Is determined as the contracted face value (approximately constant amount) of the buy order and sell order, and the purchase including the contracted face value (approximately constant amount) of the determined purchase order. Order fulfillment And the contract execution data including the contracted denomination (determined constant amount) of the determined sales order is stored in the transfer processing database 35 (see FIG. 6) in association with the transfer flag indicating the non-transfer status. . Then, a transaction execution processing means 23A (not shown) at the time of receiving a purchase order executes an execution target with the full face value (total quantity) of the purchase order face value (buy order quantity) or sell order face value (sell order quantity). For purchase order data or sell order data, update the execution flag from unfilled to a state indicating closed, and buy face value (buy order quantity) or partial face value of sell order face value (sell order quantity) For the purchase order data or sell order data subject to execution for which the amount (partial quantity) has been executed, the purchase order face value (buy order quantity) stored in the purchase order storage means 33 (see FIG. 4) or the sales The purchase order face amount (buy order quantity) or the sell order face value (subtract amount) is subtracted from the sale face value (sell order quantity) stored in the order storage means 34 (see FIG. 5). Sell order quantity) Performing a first-order trading process of new (step S2501 in FIG. 12).

  For example, in the numerical example of FIG. 14, a new purchase order of 7 million yen of customer A designates the brand X as the base brand (first priority brand) and the brand Y as the alternative brand (second priority brand). Since the brand Z is designated as the alternative brand (third priority brand), new buy order data first placed in the PTS market, that is, the buy order storage means 33 ( The new execution target purchase order data stored in FIG. 4) is customer A's purchase order of 7 million yen for the brand X which is the base brand (first priority brand). On the other hand, the sales order already placed in the PTS market has a sales order of 2 million yen for customer E for brand X. Accordingly, the portion corresponding to the purchase order of 7 million yen and the sell order of 2 million yen is 2 million yen, and the purchase order is a part of the 7 million yen of the customer A purchase order. 2 million yen will be executed. On the other hand, regarding the sales order, the entire sales order of customer E of 2 million yen is executed. Then, 5 million yen, which is the remaining part of the 7 million yen purchase order of customer A, remains as an uncommitted portion. On the other hand, no uncommitted portion remains in the selling order for the brand X.

  Subsequently, in the second embodiment, since the purchase order is designated up to the third priority issue (that is, the second priority issue is designated), the transaction execution processing means at the time of purchase order reception 23A (not shown), the execution target purchase order stored in the purchase order storage means 33 (see FIG. 4) in association with the execution flag indicating the unsettled state after the first sales transaction process. If there is data, the order data storage means 30 (in correspondence with the same order identification information as the order identification information stored in the purchase order storage means 33 (see FIG. 4) for the execution order buy order data. The brand identification information about the alternative brand of the second priority is acquired from the brand identification information and the priority ranking of the alternative brand stored in (see FIG. 2), and is associated with the contract flag that is in a state indicating uncommitted. Buy The brand difference for replacing the brand identification information stored in the sentence storage means 33 (see FIG. 4) from the brand identification information for the first priority standard brand to the brand identification information for the second priority alternative brand. Replacement processing is executed (step S2502 in FIG. 12).

  For example, in the numerical example of FIG. 14, since the purchase order 5 million yen of the customer A remains, the issue of the purchase order 5 million yen of the customer A is changed from the issue X that is the reference issue of the first priority to the first issue. Replace with the brand Y, which is the 2nd priority alternative.

  Thereafter, the purchase order acceptance transaction execution processing means 23A (not shown) stores the remaining order face value (remaining order quantity) of the purchase order data to be executed in the purchase order storage means 33 (see FIG. 4). The purchase order face value (buy order quantity) of the alternative issues of the second priority is associated with the same issue identification information as the issue identification information of the alternative issues of the second priority included in the purchase order data to be executed. The sales order face value (sell order quantity) stored as the remaining order face value (remaining order quantity) of the sales order data to be executed in the sales order storage means 34 (see FIG. 5) indicates the order of early acceptance. Matching the order of reception order management information, the contract amount of the purchase order and the sell order corresponding to the purchase order face value (buy order quantity) and the sell order face value (sell order quantity) for these same issues Amount (approx. Constant amount The transaction data of the buy order including the contracted face value (contract amount) of the determined buy order and the contract data of the sell order including the contract face amount (approx. Constant amount) of the determined sell order is indicated as untransferred The transfer process database 35 (see FIG. 6) is stored in association with the transfer flag that is in the state. Then, a transaction execution processing means 23A (not shown) at the time of receiving a purchase order executes an execution target with the full face value (total quantity) of the purchase order face value (buy order quantity) or sell order face value (sell order quantity). For purchase order data or sell order data, update the execution flag from unfilled to a state indicating closed, and buy face value (buy order quantity) or partial face value of sell order face value (sell order quantity) For the purchase order data or sell order data subject to execution for which the amount (partial quantity) has been executed, the purchase order face value (buy order quantity) stored in the purchase order storage means 33 (see FIG. 4) or the sales The purchase order face amount (buy order quantity) or the sell order face value (subtract amount) is subtracted from the sale face value (sell order quantity) stored in the order storage means 34 (see FIG. 5). Sell order quantity) Performing a second-order trading process of new (step S2503 in FIG. 12).

  For example, in the numerical example of FIG. 14, the purchase order 5 million yen of the customer A for the brand Y, which is the alternative brand of the second priority, remains in the PTS market. On the other hand, the sales orders for the brand Y already placed in the PTS market include a sales order of 2 million yen for the customer F and a sales order of 1 million yen for the customer G. Therefore, since the purchase order 5 million yen and the sales order 3 million yen correspond to 3 million yen, the purchase order is a part of the purchase order 5 million yen of the customer A. 3 million yen will be executed. On the other hand, regarding the selling order, all of the selling order 2 million yen of the customer F and all of the selling order 1 million yen of the customer G are executed. Then, 2 million yen, which is the remaining part of the purchase order 5 million yen of customer A, remains as an uncommitted portion. On the other hand, an uncommitted portion remains in the selling order for the brand Y.

  Subsequently, in the second embodiment, since the purchase order is specified up to the third priority issue (that is, the third priority issue is specified), the transaction execution processing means at the time of purchase order reception 23A (not shown), the execution target purchase order stored in the purchase order storage means 33 (see FIG. 4) in association with the execution flag set to the unfinished state after the second sales transaction process. If there is data, the order data storage means 30 (in correspondence with the same order identification information as the order identification information stored in the purchase order storage means 33 (see FIG. 4) for the execution order buy order data. The brand identification information about the alternative brand of the third priority is acquired from the brand identification information and the priority ranking of the alternative brand stored in (see FIG. 2), and is associated with the contract flag that is in a state indicating uncommitted. Buy The brand difference for replacing the brand identification information stored in the sentence storage means 33 (see FIG. 4) from the brand identification information for the second-priority alternative brand to the brand identification information for the third-priority alternative brand Replacement processing is executed (step S2504 in FIG. 12).

  For example, in the numerical example of FIG. 14, since the purchase order 2 million yen of the customer A remains, the issue of the purchase order 2 million yen of the customer A is changed from the issue Y which is the alternative issue of the second priority. Replace with the stock Z, which is the 3rd priority alternative.

  Thereafter, the purchase order acceptance transaction execution processing means 23A (not shown) stores the remaining order face value (remaining order quantity) of the purchase order data to be executed in the purchase order storage means 33 (see FIG. 4). The purchase order face value (buy order quantity) of the alternative stock of the three priority orders is associated with the same stock identification information as the stock identification information of the alternative stock of the third priority order included in the execution order buy order data. The sales order face value (sell order quantity) stored as the remaining order face value (remaining order quantity) of the sales order data to be executed in the sales order storage means 34 (see FIG. 5) indicates the order of early acceptance. Matching the order of reception order management information, the contract amount of the purchase order and the sell order corresponding to the purchase order face value (buy order quantity) and the sell order face value (sell order quantity) for these same issues Amount (approximately constant amount The transaction data of the buy order including the contracted face value (contract amount) of the determined buy order and the contract data of the sell order including the contract face amount (approx. Constant amount) of the determined sell order is indicated as untransferred The transfer process database 35 (see FIG. 6) is stored in association with the transfer flag that is in the state. Then, a transaction execution processing means 23A (not shown) at the time of receiving a purchase order executes an execution target with the full face value (total quantity) of the purchase order face value (buy order quantity) or sell order face value (sell order quantity). For purchase order data or sell order data, update the execution flag from unfilled to a state indicating closed, and buy face value (buy order quantity) or partial face value of sell order face value (sell order quantity) For the purchase order data or sell order data subject to execution for which the amount (partial quantity) has been executed, the purchase order face value (buy order quantity) stored in the purchase order storage means 33 (see FIG. 4) or the sales The purchase order face amount (buy order quantity) or the sell order face value (subtract amount) is subtracted from the sale face value (sell order quantity) stored in the order storage means 34 (see FIG. 5). Sell order quantity) Performing a third-order trading process of new (step S2505 in FIG. 12).

  For example, in the numerical example of FIG. 14, the purchase order 2 million yen of the customer A for the brand Z which is the alternative brand of the third priority rank remains in the PTS market. On the other hand, the selling order for the brand Z that has already been ordered in the PTS market is only 1 million yen for the selling order of the customer H. Accordingly, since the purchase order 2 million yen and the sell order 1 million yen correspond to 1 million yen, the purchase order is a part of the purchase order 2 million yen of the customer A. 1 million yen will be executed. On the other hand, regarding the sales order, the entire sales order of 1 million yen of customer H is executed. Then, 1 million yen, which is the remaining part of the purchase order 2 million yen of customer A, remains as an uncommitted portion. On the other hand, no uncommitted portion remains in the selling order for the brand Z.

  Then, the purchase order receiving transaction execution processing means 23A (not shown) performs the purchase order in association with the execution flag indicating the unsettled state after the third sales transaction process which is the final sales transaction process. If there is buy target data to be executed stored in the storage means 33 (see FIG. 4), the brand identification stored in the purchase order storage means 33 (see FIG. 4) for the execution order buy order data A brand replacement process is performed to return the information from the brand identification information about the alternative brand with the third priority to the brand identification information about the reference brand with the first priority (step S2506 in FIG. 12).

  For example, in the numerical example of FIG. 14, since a purchase order of 1 million yen of customer A remains, the issue of 1 million yen of purchase order of customer A is changed from the issue Z that is the alternative issue of the third priority. Replace with the stock X which is the standard stock of 1 priority. The purchase order 1 million yen of the customer A for the brand X which is the reference brand of the first priority order is prepared for the contract processing when the next new sell order is placed.

  On the other hand, in step S23 of FIG. 11, when the trading category is information indicating sale, the execution preparation processing means 22 performs the order in the same manner as the processing of step S5 of the first embodiment (see FIG. 8). Customer identification information included in the order data received by the reception processing means 21 and stored in the order data storage means 30 (see FIG. 2), brand identification information about individual government bonds that are securities to be sold, and sales Corresponding sales order data including the sales classification and sales order face value (sell order quantity) indicated by the information to be displayed to the order identification information, the execution flag indicating the unsettled status, and the reception order management information In addition, the sales order storage means 34 (see FIG. 5) is stored (step S26 in FIG. 11).

  Subsequently, when new execution order selling order data is stored in the selling order storage unit 34 (see FIG. 5) by the execution preparation processing unit 22 in step S26, the selling of the transaction execution processing unit 23 is immediately performed. By order execution transaction execution processing means 23B (not shown), as shown in FIG. 13, the first sale transaction process, the stock replacement process after the first sale transaction process, the second sale transaction process, the second sale transaction process The brand replacement process after the sales transaction process, the third sales transaction process, and the brand replacement process after the third sales transaction process are executed (step S27 in FIG. 11).

  In FIG. 13, the sales order face value (sell order) of the new sales order data to be executed stored in the sales order storage unit 34 (see FIG. 5) by the sales order acceptance transaction execution processing unit 23B (not shown). Quantity) and the execution target buy order stored in the purchase order storage means 33 (see FIG. 4) in association with the same brand identification information as the brand identification information included in the new execution target sell order data. The purchase order face value (buy order quantity) of the standard stock of the data is matched with the order of receipt order management information indicating the early order of receipt, and the purchase order face value (buy order quantity) and the sell order face value for these same issues The trade amount data for the buy order that includes the contract face value (approximately constant amount) of the purchase order that is determined as the contract face amount (approximately constant amount) of the buy order and sell order that corresponds to the amount (sell order quantity) And decide The contract data of the order sales including contractual denomination (contract number) order sales to be stored in the in correspondence with transfer flag is a state indicating non-transfer transfer process database 35 (see FIG. 6). Then, a transaction execution processing means 23B (not shown) at the time of accepting a sales order executes a purchase face value (buy order quantity) or a full face value (total quantity) of a sell order face value (sell order quantity). For buy order data or sell order data, update the execution flag from unfilled to a state indicating closed, and buy face value (buy order quantity) or partial face value of sell order face value (sell order quantity) For the purchase order data or sell order data subject to execution for which the amount (partial quantity) is executed, the purchase order face value (buy order quantity) stored in the purchase order storage means 33 (see FIG. 4) or sell The purchase order face amount (buy order quantity) or the sell order face amount (subtract amount) is subtracted from the sale face value (sell order quantity) stored in the order storage means 34 (see FIG. 5). Sell order quantity) Performing a first-order trading process of new (step S2701 in FIG. 13).

  For example, in the numerical example of FIG. 15, a new sales order of 8 million yen of customer E for brand X is placed in the PTS market. On the other hand, the purchase order that has already been placed in the PTS market is only ¥ 2 million for customer A for the brand X. That is, the purchase order of customer A of 2 million yen designates the stock X as the base stock (first priority stock), but the buy orders of the customers B, C and D use the stock X as the base stock (the first stock). Not specified as a priority issue). Accordingly, since the amount corresponding to the purchase order of 2 million yen and the sell order of 8 million yen is 2 million yen, the entire purchase order of customer A of 2 million yen is executed for the purchase order. On the other hand, regarding the sales order, 2 million yen, which is part of the 8 million yen sales order of customer E, is executed. Then, 6 million yen, which is the remaining part of the sales order 8 million yen of customer E, remains as an uncommitted portion. On the other hand, no uncommitted portion remains in the purchase order for the brand X.

  Subsequently, in the second embodiment, since the purchase order is designated up to the third priority issue (that is, the second priority issue is designated), the transaction execution processing means at the time of selling order reception 23B (not shown), the execution target sale order stored in the sale order storage means 34 (see FIG. 5) in association with the execution flag set to the unfinished state after the first sales transaction processing. If there is data, the order data storage means 30 (FIG. 4) is associated with the same order identification information as the order identification information stored in the purchase order storage means 33 (see FIG. 4) for the purchase order data to be executed. 2 is obtained from the brand identification information and the priority ranking of the alternative brand stored in (2), and the purchase order storage means 33 (FIG. 4 The brand replacement process is executed to replace the brand identification information stored in the reference) from the brand identification information for the reference brand of the first priority to the brand identification information for the alternative brand of the second priority (FIG. 13). Step S2702). At this time, the stock replacement process from the reference stock of the first priority order to the alternative stock of the second priority order is performed for all execution target purchase order data associated with the execution flag set to the status indicating unsettled. The sales order storage means 34 (for the execution order sales order data associated with the execution flag in which the brand identification information about the alternative brand of the second priority may be executed, or is associated with the execution flag. This may be executed only for the purchase order data to be executed, which is the same brand identification information as the brand identification information stored in FIG.

  For example, in the numerical example of FIG. 15, the purchase order of the customers B and D designates the brand X of the new execution target selling order data being processed as the alternative brand of the second priority, so that the customer B The stock of 2 million yen of the purchase order is replaced from the stock Y, which is the reference stock of the first priority, to the stock X, which is the alternative stock of the second priority, and the stock of 2 million yen of the purchase order of the customer D, The brand Z that is the reference brand of the first priority is replaced with the brand X that is the alternative brand of the second priority. Alternatively, the stock replacement process to the alternative stock of the second priority order may be performed on all the unfilled buy order data, and in this case, the buy orders of the customers B, C and D are unfilled. Therefore, the issue of customer B's purchase order of 2 million yen is replaced from issue Y, which is the reference issue of the first priority, to issue X, which is the alternative issue of the second priority, and the purchase order of customer D is 2 million yen. Is replaced with the first priority standard issue Z, the second priority alternative issue X, and the customer C's 3 million yen purchase order is changed to the first priority issue. The brand Y, which is the base brand, is replaced with the brand Z, which is the second-priority alternative brand. However, since the purchase order of the customer C is a replacement for the brand Z, the new sale of the customer E with respect to the brand X It is not involved in the processing of contracts with orders.

  Thereafter, the sales order receiving transaction execution processing means 23B (not shown) stores the sales order value (remaining order quantity) of the sales order data to be executed in the sales order storage means 34 (see FIG. 5). The purchase face storage amount 33 (see FIG. 4) is associated with the order face value (sell order quantity) and the same brand identification information as the brand identification information included in the sell order data to be executed. Match the purchase order face value (buy order quantity) of the second priority alternative brand stored as the remaining order face value (remaining order quantity) in the order data in the order of the reception order management information indicating the early reception order. For the same issue, the amount corresponding to the purchase order face value (buy order quantity) and sell order face value (sell order quantity) is determined as the contract face value (approximately constant amount) of the buy and sell orders, Of the decided buy order The purchase order execution data including the fixed amount (contracted amount) and the sales order execution data including the determined selling order amount (approx. Constant amount) are associated with the transfer flag indicating the status of untransferred. And stored in the transfer processing database 35 (see FIG. 6). Then, a transaction execution processing means 23B (not shown) at the time of accepting a sales order executes a purchase face value (buy order quantity) or a full face value (total quantity) of a sell order face value (sell order quantity). For buy order data or sell order data, update the execution flag from unfilled to a state indicating closed, and buy face value (buy order quantity) or partial face value of sell order face value (sell order quantity) For the purchase order data or sell order data subject to execution for which the amount (partial quantity) is executed, the purchase order face value (buy order quantity) stored in the purchase order storage means 33 (see FIG. 4) or sell The purchase order face amount (buy order quantity) or the sell order face amount (subtract amount) is subtracted from the sale face value (sell order quantity) stored in the order storage means 34 (see FIG. 5). Sell order quantity) Performing a second-order trading process of new (step S2703 in FIG. 13).

  For example, in the numerical example of FIG. 15, the sales order of customer E for brand X remains 6 million yen. On the other hand, the purchase order for the brand X includes a purchase order of customer B of 2 million yen and a purchase order of customer D of 2 million yen. Accordingly, the amount corresponding to the purchase order of 4 million yen and the sell order of 6 million yen is 4 million yen, and therefore, regarding the purchase order, the entire purchase order of customer B of 2 million yen and the purchase of customer D The entire order of 2 million yen is executed. On the other hand, regarding the sales order, 4 million yen, which is a part of the sales order 6 million yen of customer E, is executed. Then, 2 million yen which is the remaining part of the sales order 6 million yen of the customer E remains as an uncommitted portion. On the other hand, no uncommitted portion remains in the purchase order for the brand X.

  Subsequently, in the second embodiment, since the purchase order is designated up to the third priority issue (that is, the third priority issue is designated), the transaction execution processing means at the time of selling order reception 23B (not shown), the execution target sale order stored in the sale order storage means 34 (see FIG. 5) in association with the execution flag set in the state indicating unsettled after the second sales transaction processing. If there is data, the order data storage means 30 (FIG. 4) is associated with the same order identification information as the order identification information stored in the purchase order storage means 33 (see FIG. 4) for the purchase order data to be executed. 2), the brand identification information about the alternative brand of the third priority order is acquired from the brand identification information and the priority ranking of the alternative brand stored in (2), and the purchase order storage means 33 (see FIG. 4 The brand replacement process is executed to replace the brand identification information stored in (3) with the brand identification information about the alternative brand of the second priority order to the brand identification information about the alternative brand of the third priority order (FIG. 13). Step S2704). At this time, the stock replacement process from the second-priority alternative issue to the third-priority alternative issue is performed for all execution target purchase order data associated with the execution flag that is in a state indicating unsettled. The selling order storage means 34 (for the execution order selling order data associated with the execution flag in which the brand identification information about the alternative brand of the third priority order indicates an unfilled state may be executed. This may be executed only for the purchase order data to be executed, which is the same brand identification information as the brand identification information stored in FIG.

  For example, in the numerical example of FIG. 15, the purchase order of the customer C specifies the brand X of the new execution target selling order data being processed as an alternative brand of the third priority, so The brand with the order of 3 million yen is replaced with the brand X as the alternative brand with the third priority from the brand Y as the standard brand with the first priority. Alternatively, when the stock replacement process to the alternative stock of the second priority order is performed for all uncommitted buy order data in step S2702, the third order for all uncommitted buy order data in this step S2704. In this case, since the purchase order of the customer C is not yet fulfilled, the issue of the customer C 3 million yen is selected as the second priority order. The brand Z, which is the alternative brand, is replaced with the brand X, which is the third-priority alternative brand. Since all the purchase orders of the customers A, B, and D are filled, there is no uncommitted portion, so the brand replacement process is not performed.

  Thereafter, the sales order receiving transaction execution processing means 23B (not shown) stores the sales order data stored in the sales order storage means 34 (see FIG. 5) as the remaining order face value (remaining order quantity) of the sales order data to be executed. The purchase face storage amount 33 (see FIG. 4) is associated with the order face value (sell order quantity) and the same brand identification information as the brand identification information included in the sell order data to be executed. Match the purchase order face value (buy order quantity) of the third priority alternatives stored as the remaining order face value (remaining order quantity) in the order data in the order of the reception order management information indicating the early reception order. For the same issue, the amount corresponding to the purchase order face value (buy order quantity) and sell order face value (sell order quantity) is determined as the contract face value (approximately constant amount) of the buy and sell orders, Of the decided buy order The purchase order execution data including the fixed amount (contracted amount) and the sales order execution data including the determined selling order amount (approx. Constant amount) are associated with the transfer flag indicating the status of untransferred. And stored in the transfer processing database 35 (see FIG. 6). Then, a transaction execution processing means 23B (not shown) at the time of accepting a sales order executes a purchase face value (buy order quantity) or a full face value (total quantity) of a sell order face value (sell order quantity). For buy order data or sell order data, update the execution flag from unfilled to a state indicating closed, and buy face value (buy order quantity) or partial face value of sell order face value (sell order quantity) For the purchase order data or sell order data subject to execution for which the amount (partial quantity) is executed, the purchase order face value (buy order quantity) stored in the purchase order storage means 33 (see FIG. 4) or sell The purchase order face amount (buy order quantity) or the sell order face amount (subtract amount) is subtracted from the sale face value (sell order quantity) stored in the order storage means 34 (see FIG. 5). Sell order quantity) Performing a third-order trading process of new (step S2705 in FIG. 13).

  For example, in the numerical example of FIG. 15, the sales order 2 million yen of the customer E for the brand X remains. On the other hand, the purchase order for the brand X is only 3 million yen for the purchase order of the customer C. Therefore, since the portion corresponding to the purchase order of 3 million yen and the sell order of 2 million yen is 2 million yen, the purchase order is a part of the purchase order of 3 million yen of the customer C. 2 million yen will be executed. On the other hand, regarding the sales order, the entire sales order of customer E of 2 million yen is executed. Then, 1 million yen, which is the remaining part of the 3 million yen purchase order of customer C, remains as an uncommitted portion. On the other hand, no uncommitted portion remains in the sales order of the customer E for the brand X.

  Subsequently, the transaction execution processing means 23B (not shown) at the time of accepting a sales order purchases the third sale transaction process, which is the final sale transaction process, in association with the execution flag set to an uncommitted state. If there is execution target buy order data stored in the order storage means 33 (see FIG. 4), the brand stored in the purchase order storage means 33 (see FIG. 4) for the execution target buy order data. A brand replacement process is executed to return the identification information from the brand identification information for the alternative brand of the third priority to the brand identification information for the reference brand of the first priority (step S2706 in FIG. 13).

  For example, in the numerical example of FIG. 15, since the purchase order of customer C of 1 million yen remains, the issue of 1 million yen of purchase order of customer C is changed from issue X as the alternative issue of the third priority. Replace with the stock Y, which is the reference stock of 1 priority. The purchase order of 1 million yen of the customer C for the brand Y which is the reference brand of the first priority order is prepared for a contract process when a new sell order is next placed.

  Thereafter, in the same manner as in step S13 (see FIG. 8) of the first embodiment, the transfer processing unit 24 associates the transfer flag with the transfer flag indicating non-transfer by the transfer processing unit 24 (see FIG. 6). The fund balance data and the securities balance data stored in the customer account database 36 are updated using the contract data stored in, and the transfer flag in the transfer processing database 35 is changed from a non-transfer to a state indicating transfer (see FIG. 11 step S28), a series of buying and selling processing is ended (step S29).

  According to such 2nd Embodiment, there exist the following effects. That is, in the government bond transaction processing system 10 according to the second embodiment, as in the case of the first embodiment, the customer can place a priority order on a plurality of issues and place a purchase order. When the purchase order is received, the transaction execution processing means 23 replaces the purchase order brand according to the priority order, and the purchase order face value (buy order quantity) and the sell order face value (sell order quantity) of the same brand. ), The customer can have many opportunities to purchase stocks that meet the desired conditions, and can increase trading opportunities. In addition, the possibility of execution can be increased as compared with the case of the conventional buying and selling process in which only one brand to be traded is designated and ordered. In addition, from these, it is possible to revitalize trading transactions between customers (between individuals) for individual government bonds and increase the liquidity of individual government bonds, so that not only buyers but also sellers Can also have a profit.

  In addition, in the second embodiment, a method of executing a contract processing immediately after a new order is placed on the market (a method similar to the so-called Zaraba method) is adopted. When accepted, the processing of steps S2501 to S2506 shown in FIG. 12 is performed, and when the normal selling order without priority is received, the processing of steps S2701 to S2706 shown in FIG. 13 is performed.

And the time-first principle of fulfilling can be realized. Therefore, when a buy order of the same brand or a sell order of the same brand competes, it is possible to give priority to a customer who has previously made a buy order or a sell order.

  [Third Embodiment]

  16 to 18 are flowcharts showing the flow of trading processing by the government bond trading processing system 10 according to the third embodiment of the present invention, and FIG. 19 is a detailed explanatory diagram of execution preparation processing in this trading processing. Has been. In the first embodiment, a method of executing a contract processing at a predetermined contract processing time (a method similar to a so-called plate approach method) is adopted, and in the second embodiment, each time a new order is placed on the market. Whereas a method of executing a contract processing immediately (a method similar to the so-called Zaraba method) was adopted, in the third embodiment, a method of executing a contract processing immediately whenever a new order is placed on the market. (Similar to the so-called Zaraba method) is the same as in the second embodiment, but in the second embodiment, the brand of the purchase order data to be executed that has been ordered to the PTS market is changed. In the third embodiment, the purchase order quantity of the purchase order data is allocated to each designated brand according to the priority order, while the process of sequentially replacing the priority order is performed. To place orders with It is different from that done. Accordingly, the processing contents by the execution preparation processing means 22 and the transaction execution processing means 23 are different from those in the first and second embodiments, but other configurations and processing contents are the same as those in the first and second embodiments. 1 are the same as those in the first embodiment, and the following points are different from those in the first and second embodiments. The explanation will be given mainly.

  The execution preparation processing means 22 of the third embodiment accepts the order data received by the order reception processing means 21 and accepts order management information for preferentially executing the order of the customer previously ordered (buy order and Information indicating that the order of purchase / sale received by the order reception processing means 21 indicates a purchase. In the case of, at least one execution target purchase order data created by allocating the following purchase order face value (buy order quantity) to each priority issue, order identification information, unsettled Processing for storing in the purchase order storage means 33 (see FIG. 4) in association with the contracted flag set in the state and the reception order management information, and the trading area of the order data received by the order reception processing means 21 Is information indicating sale, customer identification information, brand identification information on individual government bonds that are the securities to be sold, the trading category designated as information indicating sale, and the face value of the sales order (sell order) Sales order data including the quantity) is stored in the sales order storage means 34 (see FIG. 5) in association with the order identification information, the execution flag indicating the unsettled status, and the reception order management information. The process is executed.

  Here, when the trade classification of the order data received by the order reception processing means 21 is information indicating buying, as described above, the execution preparation processing means 22 sets the purchase order face value (buy order quantity) for each item. At least one execution target purchase order data distributed to the priority issues is created, but in the third embodiment, as an example, the purchase order is specified by specifying up to the alternative issues of the third priority. Therefore, the execution order buy order data created by the execution preparation processing means 22 is only the purchase order data for the reference issue with the first priority, or the alternative issue with the second priority. Is added to the purchase order data for, and further to this is the purchase order data for the alternative issues of the third priority.

  More specifically, if the order classification received by the order reception processing means 21 is information indicating purchase, that is, if the purchase order data is received by the order reception processing means 21, the execution preparation processing means 22 The selling order associated with the same brand identification information as the brand identification information about the reference brand and the alternative brand (two alternative brands in the third embodiment) of the purchase order data received by the order reception processing means 21. The selling order face amount (sell order quantity) of each execution target selling order data stored in the storage means 34 (see FIG. 5) is acquired, and the total selling order face amount of each acquired execution order selling order data A process of calculating the amount (total quantity of sell order quantity) U is executed. More specifically, the total amount (the total quantity of the sales order quantity) U1 of the selling order face value of the selling order data to be executed for the reference issue of the first priority specified in the buying order, and the buying order are designated. Further, the total amount of the face value of the selling order data (the total quantity of the selling order quantity) U2 in the selling order data subject to execution for the alternative issue of the second priority, and the alternative issue of the third priority specified in the buy order The total amount of the sales order face value (total quantity of the sales order quantity) U3 of the sales order data to be executed is totaled to calculate U = U1 + U2 + U3.

  Further, the execution preparation processing means 22 includes the purchase order face value (buy order quantity) K of the buy order data received by the order reception processing means 21 and the total amount (sell order quantity) U of the sell order face value. If the total price of the selling order face value (total quantity of the selling order quantity) U is equal to or greater than the buying order face value (buy order quantity) K, the customer identification information and the first priority reference issue Stock identification information, and the order face value (order quantity) consisting of the smaller amount (quantity) of the purchase order face value (buy order quantity) K and the sell order face value (sell order quantity) U1 of the base issue The purchase order data to be executed is stored in the purchase order storage means 33 (see FIG. 4) in association with the order identification information, the execution flag indicating the unsettled status, and the reception order management information. Face value (Buy order quantity) K If the sell order face value (sell order quantity) U1 of the base issue is larger than the buy order face value (buy order quantity) K, the sell order face amount (sell order quantity) U1 of the first priority base issue is calculated. The reduced amount (quantity) (K-U1) is distributed as the purchase order face value (purchase order quantity) of alternative issues below the second priority in accordance with the priority order, customer identification information, second priority Execution of purchase order data for each execution target including each issue identification information for alternative issues below the rank and each assigned purchase order face value (each purchase order quantity), with the order identification information and a status indicating unsettled A process of storing in the storage unit 33 for purchase order (see FIG. 4) in association with the flag and the reception order management information is executed.

  Further, the execution preparation processing means 22 determines the customer identification information, the first priority when the total amount of the sales order face value (total quantity of the sales order quantity) U is less than the purchase order face value (buy order quantity) K. The stock identification information for the base stock of the ranking, and the total amount of the selling order face value of the alternative stocks below the second priority from the buying order face amount (buying order quantity) K (total quantity of the selling order quantity) UT (this item) In the third embodiment, purchase order data to be executed including an order face value (order quantity) consisting of (K−UT), which is an amount (quantity) obtained by subtracting UT = U2 + U3), order identification information, uncommitted Stored in the purchase order storage means 33 (see FIG. 4) in association with the status of the execution flag and the reception order management information, the total amount of the selling order face value of the alternative brands of the second priority or lower (the selling order) Total quantity) UT According to the priorities, the purchase order face value (purchase order quantity) of alternative issues below the second priority is allocated, customer identification information, each issue identification information about the alternative issues below the second priority, and each allocated purchase The purchase order storage means 33 is associated with each execution target purchase order data including the order face value (each purchase order quantity) in association with the order identification information, the execution flag indicating unsettled status, and the reception order management information. The processing to be stored in (see FIG. 4) is executed.

  The transaction execution processing means 23 of the third embodiment includes a purchase order acceptance transaction execution processing means 23A (not shown) and a sales order acceptance transaction execution processing means 23B (not shown).

  The transaction execution processing means 23A (not shown) at the time of acceptance of a purchase order each time a new order execution target purchase order data is stored in the purchase order storage means 33 (see FIG. 4) by the execution preparation processing means 22. The purchase order face value (buy order quantity) of the reference stock stored as the order face value (order quantity) of the new execution target buy order data in the storage means 33 (see FIG. 4) and each of the second priority or lower The purchase order face value (buy order quantity) of the alternative issue, the issue identification information for the reference issue included in the new execution target purchase order data, and the issue identification information for each alternative issue below the second priority The sales order face value (sell order quantity) stored as the order face value (order quantity) of the sales order data to be executed in the sales order storage means 34 (see FIG. 5) in association with the same brand identification information. Are matched in the order of the reception order management information indicating the early reception order, and the amount corresponding to the purchase order face value (buy order quantity) and the sell order face value (sell order quantity) for these same issues is determined. Execution targets that are determined as the contracted face value of the buy and sell orders (approx. Constant amount), and the full face value (total quantity) of the purchase order face value (buy order quantity) or sell order face value (sell order quantity) is executed For purchase order data or sell order data, update the execution flag from unfilled to a state indicating closed, and buy face value (buy order quantity) or partial face value of sell order face value (sell order quantity) For the purchase order data or sell order data subject to execution for which the amount (partial quantity) has been executed, the purchase order face value (buy order quantity) stored in the purchase order storage means 33 (see FIG. 4) or the sales Memory for order 34 (see FIG. 5), the purchase order face value (buy order quantity) or the sell order face value (sell order quantity) by subtracting the contract face value (about constant quantity) from the sale order face value (sell order quantity) stored in 34 Is executed.

  The transaction execution processing means 23B (not shown) at the time of sales order reception is the same as in the second embodiment, and the execution preparation processing means 22 adds a new execution target to the sales order storage means 34 (see FIG. 5). Each time sales order data is stored, the following first sales transaction processing, brand replacement processing after the first sales transaction processing, each sales transaction processing after the second sales transaction processing, and second The brand replacement process after each sales transaction process after the next sales transaction process (in the second embodiment, it is up to the third sales transaction process and the brand replacement process after the third sales transaction process). It is something to execute. Since the contents of these processes are the same as in the case of the second embodiment, description thereof is omitted.

  In the third embodiment as described above, the government bond trading processing system 10 executes the trading process for individual government bonds as follows.

  In FIG. 16, the processing by the government bond trading processing system 10 is started (step S41), and the order reception processing means 21 performs the processing of steps S2 and S22 of the first and second embodiments (see FIGS. 8 and 11). Similarly, the customer order data transmitted from the terminal device 40 via the network 1 is received, order identification information (order number) is automatically given to the received order data, and depending on the form of the received purchase order data In the state in which each priority order is determined and the determination result is added, the order data is stored in the order data storage means 30 (see FIG. 2) in association with the order identification information (order number) (FIG. 16). Step S42).

  Then, the execution preparation processing means 22 receives and receives the order data storage means in the same manner as the processing of steps S3 and S23 of the first and second embodiments (see FIGS. 8 and 11). 30 (see FIG. 2), the order data stored in the order data is referred to (step S43 in FIG. 16). Execution preparation processing, that is, the purchase order face amount (buy order quantity) included in the order data received by the order reception processing means 21 and stored in the order data storage means 30 (see FIG. 2) At least one execution target purchase order data distributed and created is associated with order identification information, a contract flag indicating unsettled status, and acceptance order management information, and stores for purchase orders Executing a process of storing in the stage 33 (see FIG. 4) (step S44 in FIG. 16).

  In FIG. 17, the execution preparation processing means 22 is identical to the brand identification information for the reference brand and the alternative brands (two alternative brands in the third embodiment) of the purchase order data received by the order reception processing unit 21. The sales face value (sell order quantity) of the sales order data of each execution target stored in the sales order storage means 34 (see FIG. 5) in association with the brand identification information is acquired, and each acquired execution target Processing for calculating the total amount (total amount of sales order quantity) U of the sales order face value of the sales order data is executed (step S4401 in FIG. 17). More specifically, the execution preparation processing means 22 acquires the selling order face value (sell order quantity) of the selling order data to be executed for the reference issue of the first priority specified in the purchase order, If there is sell order data subject to execution, the total amount of the sell order face value (total quantity of sell order quantity) U1 is calculated, and the second priority alternative brand specified in the buy order is calculated. If the selling order face value (sell order quantity) of the sales order data subject to execution is obtained, and there are multiple corresponding sales order data subject to execution, the total amount of those selling order face values (of the sales order quantity) Total quantity) U2 is calculated, and the face value (sell order quantity) of the sell order data of the execution target for the alternative stock of the third priority specified in the buy order is obtained, and the corresponding multiple execution target When there is sell order data To calculates the U3 (total quantity of sales order quantity) total amount of their sales order par value, to calculate the U = U1 + U2 + U3 is these of the total amount (total quantity).

  Subsequently, the execution preparation processing means 22 uses the purchase order face value (buy order quantity) K of the purchase order data received by the order reception processing means 21 and the total price of the sell order face value (total quantity of the sell order quantity) U. And whether or not the total amount of the selling order face value (total quantity of selling order quantity) U is equal to or larger than the buying order face value (buying order quantity) K is determined (step S4402 in FIG. 17).

  Here, when it is determined that the total amount of the sales order face value (total quantity of the sales order quantity) U is equal to or larger than the purchase order face value (buy order quantity) K, the execution preparation processing means 22 performs customer identification information. , Stock identification information about the reference stock of the first priority level, and the purchase order face value (buy order quantity) K and the sell order face value (sell order quantity) U1 of the reference stock, whichever is smaller (quantity) The purchase order storage means 33 (FIG. 5) is associated with the execution order buy order data including the order face value (order quantity) to be associated with the order identification information, the execution flag indicating unsettled status, and the reception order management information. 4) (step S4403 in FIG. 17). In FIG. 19, the process in the case (1), that is, the process in any of (1-1), (1-2), and (1-3).

  Subsequently, the execution preparation processing means 22 determines whether or not the purchase order face value (buy order quantity) K is larger than the sell order face value (sale order quantity) U1 of the reference issue (step S4404 in FIG. 17). In the case of being larger, the execution preparation processing means 22 calculates the first priority standard issue from the customer identification information, the issue identification information about the alternative issue of the second priority, and the purchase order face value (buy order quantity) K. The smaller one of (K-U1), which is the amount (quantity) obtained by subtracting the sales order par value (selling order quantity) U1, and the selling order par value (selling order quantity) U2 of the second-priority alternative issue For purchase orders, the purchase order data to be executed including the face value (order quantity) consisting of the amount (quantity) is associated with the order identification information, the execution flag indicating unsettled status, and the reception order management information. Storage means 33 (see FIG. Is stored in the reference) (step S4405 in FIG. 17). In FIG. 19, it is the process in the case of (1-2) or (1-3).

  Further, the execution preparation processing means 22 is an amount (quantity) obtained by subtracting the selling order face amount (sell order quantity) U1 of the reference issue of the first priority from the buying order face amount (buy order quantity) K (K−). It is determined whether or not U1) is larger than the selling order face value (selling order quantity) U2 of the alternative issue of the second priority (step S4406 in FIG. 17). , Customer identification information, brand identification information about the alternative brand of the third priority, and buy order face value (buy order quantity) K, and the sell order face value (sell order quantity) U1 of the reference brand of the first priority The purchase order subject to execution including the order amount (order quantity) consisting of (K-U1-U2), which is the amount (quantity) obtained by subtracting the sales order amount (selling order quantity) U2 of the alternative issue of the second priority. Data, order identification information Commitments flag is a state indicating uncommitted, and is stored in the reception order management information and association with buy-order storage unit 33 (see FIG. 4) (step S4407 in FIG. 17). In FIG. 19, it is the process in the case of (1-3). Then, the process proceeds to the next step S45.

  If it is determined in step S4404 that the purchase order face amount (buy order quantity) K is equal to or less than the sell order face amount (sale order quantity) U1 of the reference issue, the process directly proceeds to step S45. This is the case of (1-1) in FIG. 19. In this case, only the buy order data for the execution target for the reference issue of the first priority order is created, and the alternative issue issues of the second and third priority orders are created. The purchase order data to be executed is not created.

  In step S4406, (K-U1) is an amount (quantity) obtained by subtracting the selling order face amount (sale order quantity) U1 of the reference issue of the first priority from the buying order face amount (buy order quantity) K. If it is determined that the selling order face value (selling order quantity) U2 of the alternative brand of the second priority is equal to or less than U2, the process proceeds to step S45 as it is. This is the case of (1-2) in FIG. 19. In this case, execution target purchase order data for the first priority standard issue and execution target buy order data for the second priority alternative issue And the buy order data to be executed for the alternative issues of the third priority order is not created.

  On the other hand, if it is determined in step S4402 that the total amount of the sales order face value (total quantity of the sales order quantity) U is less than the purchase order face value (buy order quantity) K, the execution preparation processing means 22 The total amount (total amount of the sales order quantity) UT of the selling order face value of the alternative brands having the second priority or lower is calculated (step S4408 in FIG. 17). In the third embodiment, UT = U2 + U3.

  Subsequently, the execution preparation processing means 22 sells the customer identification information, the brand identification information about the reference brand of the first priority, and the selling order of the alternative brand having the second priority or lower from the purchase order face value (buy order quantity) K. The total amount of face value (total quantity of selling order quantity) UT (in this third embodiment, UT = U2 + U3) is the amount (quantity) obtained by subtracting the order amount (order quantity) consisting of (K−UT). The purchase order data to be executed is stored in the purchase order storage means 33 (see FIG. 4) in association with the order identification information, the execution flag indicating the unsettled status, and the reception order management information (see FIG. 4). Step S4409). This is the process in the case of (2) in FIG. 19. In this case, the entire purchase order face value (buy order quantity) K cannot be filled, and the unfilled remaining order face value (remaining order quantity). Therefore, the face value (quantity) which is the uncommitted amount remains as purchase order data to be executed for the reference issue of the first priority.

  Then, the execution preparatory processing means 22 uses the priority order to purchase the alternative stocks below the second priority order according to the priority order. Each execution target is distributed as order face value (buy order quantity) and includes customer identification information, each brand identification information for alternative stocks of the second priority or lower, and each assigned purchase order face value (each buy order quantity) Is stored in the purchase order storage means 33 (see FIG. 4) in association with the order identification information, the execution flag indicating the unsettled status, and the reception order management information (step S4410 in FIG. 17). ). In other words, the execution preparation processing means 22 adds the customer identification information, the brand identification information about the alternative brand of the second priority order, and the total amount of the selling order face value of the alternative brand of the second priority order (the total quantity of the sales order quantity). The purchase order data to be executed including the order face value (order quantity) consisting of the same amount (quantity) as U2 is associated with the order identification information, the execution flag indicating unsettled status, and the reception order management information. And storing in the purchase order storage means 33 (see FIG. 4), the total amount of the customer identification information, the brand identification information about the alternative brand of the third priority, and the selling order face value of the alternative brand of the third priority (Total quantity of selling order quantity) The purchase order data to be executed including the order amount (order quantity) consisting of the same amount (quantity) as U3, the order identification information, an uncommitted contract Flag, and to be stored in order of reception management information associated with purchase orders storage unit 33 (see FIG. 4).

  Thereafter, when new execution order purchase order data is stored in the purchase order storage means 33 (see FIG. 4) by the execution preparation processing means 22, the transaction at the time of acceptance of the purchase order by the transaction execution processing means 23 is immediately performed at that time. The purchase order face value of the reference brand (order quantity) stored as the order face value (order quantity) of the new purchase target purchase order data in the purchase order storage means 33 (see FIG. 4) by the execution processing means 23A (not shown) Purchase order face value (buy order quantity) of each alternative stock below the second priority order, and the stock identification information and second priority for the base stock included in these new execution target buy order data The order face value (order) of the sales order data to be executed is stored in the sales order storage means 34 (see FIG. 5) in association with the same brand identification information as the brand identification information for each alternative brand below the ranking. The sales order face value (sell order quantity) stored as (quantity) is matched with the order of receipt order management information indicating the early order of receipt, and the purchase order face value (buy order quantity) and sell order for these same brands. The amount corresponding to the face value (sell order quantity) is determined as the contract face value (approximately constant amount) of the buy order and sell order, and the purchase order is executed including the contract face amount (approximately constant amount) of the determined purchase order. The sales order contract data including the data and the contracted face value (approx. Constant amount) of the determined sales order is stored in the transfer processing database 35 (see FIG. 6) in association with the transfer flag indicating the state of non-transfer. . Then, a transaction execution processing means 23A (not shown) at the time of receiving a purchase order executes an execution target with the full face value (total quantity) of the purchase order face value (buy order quantity) or sell order face value (sell order quantity). For purchase order data or sell order data, update the execution flag from unfilled to a state indicating closed, and buy face value (buy order quantity) or partial face value of sell order face value (sell order quantity) For the purchase order data or sell order data subject to execution for which the amount (partial quantity) has been executed, the purchase order face value (buy order quantity) stored in the purchase order storage means 33 (see FIG. 4) or the sales The purchase order face amount (buy order quantity) or the sell order face value (subtract amount) is subtracted from the sale face value (sell order quantity) stored in the order storage means 34 (see FIG. 5). Sell order quantity) It performs a process of new (step S45 in FIG. 16).

  In the third embodiment, as in the case of the first and second embodiments, it is possible to specify up to the third priority brands in the purchase order. In S44 (steps S4401 to S4410 in FIG. 17), the execution target buy order data created by the execution preparation processing means 22 is the largest, and the execution target buy order data for the reference issue of the first priority, There are three types of purchase order data for execution of alternative issues of the second priority and buy order data of execution targets for alternative issues of the third priority. Accordingly, in step S45 of FIG. 16, the execution target for the reference issue of the first priority stored in the purchase order storage means 33 (see FIG. 4) by the purchase order acceptance transaction execution processing means 23A (not shown). The contract processing is performed between the purchase order data and the execution order sell order data stored in the sell order storage means 34 (see FIG. 5) for the same brand, and the purchase order storage means. 33 (refer to FIG. 4), the buy order data of the execution target for the alternative stock of the second priority order stored in 33 (see FIG. 4), and the execution target stored in the selling order storage means 34 (refer to FIG. 5) for this same stock. The contract processing with the sell order data is performed, and further, the purchase order data to be executed for the alternative issues of the third priority order stored in the buy order storage means 33 (see FIG. 4), and Sales order for the same brand Means 34 contract processing between the stored execution target sales order data (see FIG. 5) is performed.

  In addition, when the trade classification is information indicating sale in step S43 of FIG. 16, the execution preparation processing means 22 stores the sales order data to be executed in the sales order storage means 34 (see FIG. 5). Execution preparation processing is executed (step S46 in FIG. 16). Since the execution preparation process of this step S46 is the same as the process of step S26 of FIG. 11 of the said 2nd Embodiment, description is abbreviate | omitted.

  Subsequently, when the execution preparation processing means 22 stores the new sales order data to be executed in the sales order storage means 34 (see FIG. 5), the transaction execution processing means 23 immediately receives the sales order. The transaction execution processing means 23B (not shown) executes a sales transaction process when new sales order data as shown in FIG. 18 is received (step S47 in FIG. 16). The sales transaction process in step S47 (steps S4701 to S4706 in FIG. 18) is the same as the process in step S27 in FIG. 11 (steps S2701 to S2706 in FIG. 13) of the second embodiment, and thus description thereof is omitted. .

  Thereafter, in the same manner as in steps S13 and S28 (see FIGS. 8 and 11) of the first and second embodiments, the transfer processing unit 24 performs a transfer in association with the transfer flag set to the non-transfer state. Using the contract data stored in the processing database 35 (see FIG. 6), the funds balance data and the securities balance data stored in the customer account database 36 are updated, and the transfer flag of the transfer processing database 35 is transferred from untransferred. The state is changed to a state indicating “completed” (step S48 in FIG. 16), and the series of buying and selling processing is ended (step S49).

  According to such 3rd Embodiment, there exist the following effects. That is, in the government bond transaction processing system 10 according to the third embodiment, as in the first and second embodiments, the customer can place a purchase order by giving priority to a plurality of issues. When a purchase order with priority is received, the transaction execution processing means 23 replaces the brand of the purchase order according to the priority, and the purchase order face value (buy order quantity) and the sell order face value of the same brand ( The customer can obtain a lot of opportunities to purchase brands that meet the desired conditions and increase the trading opportunities. In addition, the possibility of execution can be increased as compared with the case of the conventional buying and selling process in which only one brand to be traded is designated and ordered. In addition, from these, it is possible to revitalize trading transactions between customers (between individuals) for individual government bonds and increase the liquidity of individual government bonds, so that not only buyers but also sellers Can also have a profit.

  Further, in the third embodiment, as in the case of the second embodiment, a method (a method similar to the so-called Zaraba method) that immediately executes a contract every time a new order is placed on the market is adopted. However, when a purchase order with priority is received, the processing of steps S4401 to S4410 shown in FIG. 17 is performed, and when a normal sell order without priority is received, it is shown in FIG. Since the processing of steps S4701 to S4706 is performed, as in the case of the first and second embodiments, when a purchase order with a priority order is accepted, a normal sell order without a priority order is accepted. In addition to satisfying the customer's trade wishes indicated by prioritized buy orders, it is possible to increase the possibility of selling orders, It is possible to increase the volatility.

  Further, in the third embodiment, as in the case of the first and second embodiments, the transaction execution processing means 23 executes the contract processing using the reception order management information. The time-first principle of preferential execution of data can be realized. Therefore, when a buy order of the same brand or a sell order of the same brand competes, it is possible to give priority to a customer who has previously made a buy order or a sell order.

  [Deformation form]

  Note that the present invention is not limited to the above-described embodiments, and modifications and the like within a range in which the object of the present invention can be achieved are included in the present invention.

  For example, in each of the above-described embodiments, the government bond trading processing system 10 for selling and selling personal government bonds is used. However, the securities to be bought and sold by the securities buying and selling system of the present invention are for individuals. It is not limited to government bonds, but may be bonds or stocks other than personal bonds for individuals. However, since the product characteristics of personal interest-bearing national treasury bonds draw out the customer's transaction wishes that can be dealt with by the present invention, the securities trading processing system of the present invention can buy and sell personal interest-bearing national treasury bonds. It is suitable to use for the government bond transaction processing system 10 to be performed.

  In each of the above embodiments, the buy order is a buy order with priority, and the sell order is a normal sell order without priority. It may be a sell order, and the buy order may be a normal buy order without priority.

  Further, in each of the above embodiments, when the customer places an order, the customer is allowed to designate up to the third-priority alternative issue (that is, the configuration in which two alternative issues can be designated). However, the present invention is not limited to this. For example, a configuration in which up to alternative stocks of the second priority order can be specified (that is, a configuration in which only one alternative stock can be designated) may be used, or the fourth priority order may be used.
