FIG. 6 is a diagram illustrating a configuration of a DB included in the board server 3. As shown in FIG. 6A, the order information 36A includes an order number 36A1, a brand 36A2, a number of shares 36A3, a limit 36A4, a buying / selling section 36A5, a trading section 36A6, and an execution condition 36A7. Since each element is the same as each element of the order information 30A in FIG. 4C, description thereof is omitted.
As shown in FIG. 6B, the board information 36B is composed of a sale quantity 36B1, a price 36B2, and a purchase quantity 36B3 for each brand. The sale quantity 36B1 indicates the number of shares of the brand for which a sale order with a price 36B2 has been placed. The price 36B2 indicates the stock price of the brand for which a sell or buy order has been placed. The buy quantity 36B3 indicates the number of shares of the brand for which a purchase order with a price 36B2 has been issued. FIG. 6B shows that, for example, there is a selling order of 2000 shares at 1005 yen. Here, for example, if the board server 3 receives order information for selling 1000 shares at the limit of 1005 yen for the same brand, the selling quantity 36B1 corresponding to the price 36B2 of 1005 yen is "3000" (= 2000 + 1000). . The board information usually includes the number of selling orders and buying orders, but the description thereof is omitted here.

The order number 36C1 is the order number of the order information for which stock trading has been established. The contract number 36C2 is a unique number assigned to each contract, and is used to determine that a sell order and a buy order have come together. Accordingly, the same contract number 36C2 is set in the sales order contract information 36C and the corresponding buy order contract information 36C. Since each element after the contracted brand 36C3 is the same as each element of the transaction data 30B in FIG. 4D, description thereof will be omitted.

FIG. 7 is a flowchart showing the operation of this system.
In this system, the contract date = delivery date / time, that is, in order to enable T + 0 immediate settlement, an account for immediate settlement transaction is opened in a securities company. It is also assumed that the customer's stock is deposited with a securities company so that the securities themselves can be delivered immediately. Thereby, since the transaction is performed within the range of the stock and cash balances deposited from the customer, the balance data can be updated in real time, and settlement failure can be prevented.

If the customer needs to open an account (Yes in step S101), an account is opened to the transaction server 2 in order to use this system. In this case, the customer terminals 1 ₁ ... 1 _m first connect to the transaction server 2 via the Internet 4 and receive the customer account opening screen data from the customer account opening means 21. Then, according to the customer account opening screen displayed on the browsing means 12, information indicating that a customer account is desired to be opened is input to the input means 11 and transmitted to the transaction server 2.

  When the customer account opening means 21 receives information indicating that it wishes to open a customer account, and there is no error in comparing with the target person information 301 and the prospective customer information 302 stored in the personal corporation information DB 30, The fact that the customer account has been opened is stored in the customer information DB 26 of the transaction server 2 (step S102). Here, the target person information 301 is a black list of customers, the prospective customer information 302 is a list of customers who have already applied for account opening, and the customer list is collated with information regarding customers who wish to open an account. If not, it is judged that there is no flaw. If the account has been opened (No in step S101), it is not necessary to open a customer account, and the process proceeds to customer authentication for determining whether the customer is the principal.

The customer authentication means 22 receives the authentication information (ID, password, etc.) for authenticating the customer input from the input means 11 of the customer terminal 1 ₁ ... 1 _m , and the customer information of the customer contained in the customer DB 26 Authentication is carried out by checking (step S103). If the authentication is correct (Yes in S103), the process proceeds to the next step. If it is not correct (No in S103), the log-in to this system is terminated as disapproved.

Authentication information is legitimate, after logging in to the system is performed by the input of the read request, the stock information from the stock DB 24, rule information is transmitted from the rules DB25 to the customer terminal ₁ 1 ... 1 _m. Stock price information is stock information for each stock, such as stock prices that evaluate the closing price of the market, quote information (contract price, trading volume information), etc., and the rule information is various rules regarding transactions when using this system. It is. Examples of the rule information include setting of trading stocks (including deposit dates due to stock splits, restrictions on delivery dates, etc.), trading units, trading hours, reflection of regulations in exchange trading, and the like. Further, the input of the read request, reserve capacity balance in the customer account each customer owned is transmitted from the customer information DB26 to the customer terminal ₁ 1 ... 1 _m.

  This surplus balance is information on customer assets including cash and securities deposited in the customer account, trading margin in margin transactions, traded open interest, and the like.

These pieces of information are confirmed by being displayed on the browsing means 12 of the customer terminals 1 ₁ ... 1 _m , and the order desired by the customer is input to the input means 11 as order information (step S104). The order information includes a spot transaction (buy or sell) or a general credit transaction (new or repayment), the number of shares ordered, a limit price, or the like.

In the transaction server 2 that has received the order information, the order information confirmation means 23 determines whether or not the order information is appropriate (step S105). That is, it is determined whether or not the order information is appropriate with reference to the stock price information, rule information and customer information. The specific determination method is as already described in the description of the order information confirmation unit 23. When the order information is not appropriate (No in S105), for example, when the transaction server 2 is short of surplus or a shortage of balance, a surplus balance error is detected, and when the order is not in accordance with the rule information, an order error is indicated for each customer terminal 1 ₁ . _m (step S106) and waits for receiving order information.

FIG. 10 is a diagram showing a balance check performed by the order information confirmation unit 23. FIG. 10A shows a balance check after a conventional ordinary transaction (exchange transaction). First, when conducting only ordinary transactions, that is, when checking the balance for ordinary transactions after ordinary transactions, in principle, after T + 3 (four business days after the contract date = delivery date) (see solid arrows) ) Balance (cash delivered and number of shares delivered) is used for available cash and available shares. In this case, there is no problem because the balance after the delivery is reflected is used. Next, when checking the balance for an immediate settlement transaction after a normal transaction, take into account the balance after the T (contract date) (see the dashed arrows) (delivered cash, number of shares delivered, and transaction status) ) Is used for available cash and available shares. In this case, since the delivery is performed at T + 3 because it is after a normal transaction, the balance after T will increase or decrease around T + 3, but by adopting the minimum value of the balance, the number of available cash and the number of shares that can be sold Can be determined.
FIG. 10B shows the balance check after the immediate settlement transaction is performed. After performing an immediate settlement transaction, T (contract date) becomes the delivery date, so the balance (cash delivered and number of shares delivered) is fixed after T, so the balance check for ordinary transactions or the immediate settlement transaction Regardless of the balance check for, the available cash and the number of shares available for sale will be the same.
Note that the balance information shown in FIGS. 10A and 10B is stored in the account balance information 263 of the customer information DB 26 in a state where a normal transaction and an immediate settlement transaction are mixed. The

  Returning to FIG. 7, when the order information is appropriate (Yes in S105), the order order storage means 27 orders the order information from the board server 3 and stores it as the order information 30A (step S107). ). The stored order information 30A is reflected in the customer transaction information 264 of the customer information DB 26.

The board server 3 that has received the order information normally confirms whether or not the current time is within the transaction time of this system since the transaction time is determined for the transaction (step S108). If it is within the transaction time (Yes in step S108), it is confirmed whether or not the received order information is a new order (step S109). If it is a new order (Yes in step S109), the board registration means 31 registers the order information as order information 36A in the transaction information DB 36 of the second storage unit (step S110). The board information 36B is information for registering order information issued by each customer and for browsing by each customer. All the ordered order information 36A is registered in the board information 36B, the board information 36B is created by the board information creating means 32 (step S111), and the board information 36B is completed. Specifically, the stock number 36A3 of the order information 36A is added to the selling quantity 36B1 or the buying quantity 36B3 in the board information 36B in accordance with the trading category 36A5 and stored. The finished plate information 36B, by browsing request from the customer terminal 1 ₁ ... 1 _m is inputted from the input unit 11, or by voluntary operation of the plate information creation unit 32, the customer terminal 1 ₁ ... 1 _m It is transmitted to (step S112). At the customer terminals 1 ₁ ... 1 _m receiving the board information, the browsing means 12 displays the board information.

  In order for a stock transaction to be established, it is essential to have order information corresponding to certain order information (a sell order for a buy order and a buy order for a sell order). For this reason, the contract means 34 confirms whether there is corresponding order information (step S113). The process when there is corresponding order information (Yes in step S113) will be described later using the flowchart of FIG. When there is no corresponding order information (No in step S113), the board server 3 waits for receiving the order information.

If the current time is not within the transaction time (No in S108), the board server 3 returns a message indicating an overtime error to the transaction server 2 (step S114). In this case, the transaction server 2 receives the message from the board server 3 and transmits the message to the customer terminals 1 ₁ ... 1 _m that received the original order information. Customer terminals 1 ₁ ... 1 _m receive the message from transaction server 2 and display it on the display. As a result, the customer recognizes that it is out of business hours. The processing of the board server 3 when the transaction time ends will be described later using the flowchart shown in FIG.

If the order information is not a new order (No in step S109), it is determined whether or not there is an original order to be changed or deleted (step S115). When there is original order of the change or deletion requested (Yes in step S115), the information in the leaf server 3, the order information changing deleting unit 33, which is input by the customer terminal 1 ₁ ... 1 input means 11 of the _m Based on this, the order information of the corresponding customer is changed or deleted (step S116), and the registration to the board information 36B and the creation of the board information 36B are performed again (step S111).

If there is no original order to be changed or deleted (No in step S115), the board server 3 returns a message indicating an acceptance error to the transaction server 2 (step S117). In this case, the transaction server 2 receives the message from the board server 3, transmits the message to the customer terminals 1 ₁ ... 1 _m that received the original order information, and waits for receiving the order information. Customer terminals 1 ₁ ... 1 _m receive the message from transaction server 2 and display it on the display. Thus, the customer recognizes that the order information has not been received by the board server 3.

  FIG. 8 is a flowchart showing the contract processing when there is corresponding order information in this system.

  As described above, a contract is established when there is corresponding order information. That is, it is established when there is an order for selling for buying and buying for selling. Here, the trading price determination method that can be carried out by PTS (Proprietary Trading System) includes market price trading method (selling using trading price of exchange), customer negotiation method ( Customers buy and sell at a price agreed with each other), customer order matching method (buying and selling when there is a limit that matches the limit presented by the customer), buying and selling quote presentation method (the securities company presents the selling and buying quotes) , Buying and selling using prices based on these), and auction method (similar method to an exchange).

  Upon confirming the corresponding order information, the contracting means 34 contracts the corresponding order information (step S201), and then deletes the contracted order information from the board information 36B to the board information creating means 32, A trigger is given to execute the process of step S111 of FIG. In parallel with the processing, the contract means 34 creates a contract message and transmits it to the transaction server 2 (step S202). Then, the contracted order information is deleted from the board information 36B, and the contracted order information and the contracted date and time (the contents of the contract telegram) are stored in the contract information 36C of the transaction information DB 36 (step S203). Thereby, the contract processing in the board server 3 is completed. The contract message has the same configuration as the contract information 36C in FIG.

  Here, a specific example of deleting the contracted order information from the board information 36B will be described. In the board information 36B of FIG. 6B, for example, when 1500 shares are sold for a stock price of 1003 yen, 1500 shares are subtracted from the sell quantity 36B1 and the buy quantity 36B3 corresponding to the price 36B2 of 1003 yen. As a result, in the board information 36B after the contracted order information is deleted, the selling quantity 36B1 corresponding to the price 36B2 of 1003 yen is 0 shares, and the corresponding buying quantity 36B3 is 1500 shares.

On the other hand, in the transaction server 2 that has received the contract message, the transaction data creation storage means 28 creates and stores the transaction data 30B based on the contract message (step S204). The transaction data 30B is a customer account ledger, a security deposit book, a transaction diary, an order slip, etc. including the contents shown in FIG.
Then, the transaction result reflection unit 29 updates the customer information DB 26 including the remaining balance of the customer based on the transaction data 30B to a state in which payment is made immediately (step S205). In the update of the customer information DB 26, based on the contract name 30B1, the number of shares 30B2, the amount 30B3, the contract date 30B4, the trading category 30B5 of the transaction data 30B, etc. Update the H.264 contract details.
Here, before executing the process of step S <b> 204, the first processing unit of the transaction server 2 checks the contract number included in the contract message received from the board server 3. That is, for a certain contract number, it is confirmed whether or not both the contract telegram of the sell order and the contract telegram of the buy order have been received. If both have been received, the processing of steps S204 and S205 is executed. If one has been received and the other has not been received, the process of steps S204 and S205 is executed after the other is received. According to this, the execution of the settlement process is ensured by ensuring the consistency of the contract message, and the settlement is completed at the same time as the contract, so it is possible to prevent the settlement default.
As shown in Fig. 10, whether or not you have a balance of cash or stock (excluding undelivered portion in ordinary transactions) that can be used for immediate settlement transactions when you receive an order from a customer Since there is no check, there will be no shortage of balance after the transaction is executed.

FIG. 9 is a flowchart showing the processing when the transaction time has elapsed in this system.
When the transaction time elapses, confirmation of the transaction performed within the transaction time in the present system and resetting of the board information are performed.

  The board server 3 outputs the contract information 36C stored in the transaction information DB 36 as a contract verification file (step S301). Next, the order information change deletion means 33 deletes the unordered order information from the board information 36B (step S302). Then, the output contract collation file and the transaction data 30B stored by the transaction data creation storage unit 28 of the transaction server 2 are collated by the transaction result reflection unit 29 (step S303). As a result of matching, if the agreement matching file and the transaction data 30B are not consistent, an error is output. Further, the final result after the transaction is reflected in the customer information DB 26 by the transaction result reflecting means 29 (step S304).

Incidentally, stock DB 24, rule DB 25, the customer's own customer information including the reserve capacity balance stored in the customer information DB 26, and the plate information 36B is a view request inputted from the customer terminal ₁ 1 ... _{1 m} of the input means 11, It is transmitted from the transaction server 2 and the board server 3 as needed to the customer terminals 1 ₁ ... 1 _{m and} can be displayed by the browsing means 12.

Although the best mode for carrying out the present invention has been described above, the above embodiment is intended to facilitate understanding of the present invention and is not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and equivalents thereof are also included in the present invention.
For example, although the above embodiment has been described with respect to an immediate settlement transaction for stocks, it can be applied to an immediate settlement transaction for securities that can be electronically settled. Here, “electronic payment is possible” means that payment is possible by exchanging electronic data.
Further, for example, the immediate settlement transaction described above can be applied not only to a spot transaction but also to a general credit transaction. In that case, the transaction server 2 is provided with a securities company information DB in addition to the customer information DB 26. The securities company information DB stores the purchase funds used by the customer for general credit transactions, the balance information of the stock certificates sold, and the loan limit information thereof. When using the general margin transaction, the customer can receive the loan of the purchased funds or the stock certificates for sale up to the amount indicated by the loan limit information stored in the securities company information DB. When the loan is received, the stock company or the selling price is inserted into the securities company.
Specifically, the transaction server 2 judges from the contract message received from the board server 3, and transfers the securities from the securities company information DB to the customer information DB 26 of the other party of the customer who uses the general credit transaction (hereinafter referred to as a customer). The balance information of the DB is updated so that the purchase funds or stock certificates to be lent to the customer are transferred by the company. Then, the balance information in the DB is updated so that the stock certificate or the selling price that the securities company should receive from the customer is transferred from the customer information DB 26 of the other party of the customer to the securities company information DB.
Thus, in the general credit transaction, the transaction server 2 performs settlement by updating the customer information DB 26 and the securities company information DB of the customer other than the customer customer DB 26 of the customer. The loan limit is checked by referring to the loan limit information in the securities company information DB at the time of placing an order. The event of stagnation does not occur.
