BACKGROUND OF THE INVENTION
The present invention relates to a transaction verification support system that supports verification of transaction validity. More specifically, the present invention accumulates events that occur due to orders, etc. up to a specified time, reproduces the transaction status at the specified time, and verifies transaction validity. A transaction verification support system for supporting
[0002]
The present invention also relates to such a transaction verification support method and a storage medium storing a program for causing a computer to perform processing in the system.
[0003]
[Prior art]
Traditionally, TSE (Tokyo Stock Exchange) trades stocks in the presence of exchanges in the presence of brokers (members). (Trade) orders are recorded in the transaction record for each order. In addition, for example, in the case of general brands, the staff of the exchange organizes the buying and selling orders written on the transaction slip (board), the selling order is from the cheaper price, the buying order from the higher price The order was filled by deciding the price together (boarding).
[0004]
[Problems to be solved by the invention]
The stock price is affected by the published information and goes up and down. When good information that is largely involved in increasing the price of a traded product is disclosed, the price rises because the quantity of buy orders for that traded product increases. On the other hand, when bad information largely related to the decline in the price of a trading product is disclosed, the price falls because the quantity of sell orders for the trading product decreases. Some investors who knew the information before such important information was released, if the information is good information, after purchasing the product in advance and after the information is released If the same transaction product is immediately sold, it is possible to obtain a profit based on the price information of the transaction product in a short time. Conversely, if the information is bad information, sell the transaction product in advance, and immediately purchase the same transaction product after the information has been released, then you can profit from the price drop of the transaction product in a short period of time. It is possible to obtain. An investor who executes such a specific transaction observes whether or not a trading contract for a trading product for that trading product has been established or has not yet been established, and after a certain period, If it has not been established, immediately enter a buy / sell order against the trade order of the traded product and cancel it. Therefore, when auditing a specific transaction at the past time point, first, a transaction slip is extracted from all transaction records for a certain period including before that point, and then an individual transaction slip for a specified transaction product is extracted. Further, it is necessary to perform a three-step process for identifying the purchase order (or sell order) for the sell order (or buy order) of the same member and the same customer. Therefore, a lot of time and troublesome work is required to audit a specific transaction.
[0005]
Accordingly, a first object of the present invention is to provide a transaction verification support system that accumulates events that occur due to orders or the like up to a specified time, reproduces the transaction status at the specified time, and supports verification of unauthorized transactions.
Similarly, the second problem of the present invention is to provide a transaction verification support method for accumulating events that occur due to orders or the like up to a specified time, reproducing the transaction status at the specified time, and supporting the verification of fraudulent transactions. It is.
[0006]
Furthermore, a third object of the present invention is to provide a storage medium storing a program for causing a computer to perform processing in the transaction verification support system as described above.
[0007]
[Means for Solving the Problems]
  In order to solve the first problem, as described in claim 1, the present invention shows a transaction situation actually performed to verify a transaction event related to an order made for each transaction product. In the transaction verification support system that reproduces the screen, at least the date when the transaction event occurred as transaction event information for each transaction event related to the orderAndTimeTimeA transaction event storage means for associating the transaction product, the transaction type, the information for identifying the member who has performed the transaction, the transaction quantity, and the price with each other stored in the database;An acquisition means for acquiring a date and time for extracting the transaction event information and a transaction product from a user;the aboveAcquiredDayIn the appendix, the transaction event information indicating the acquired transaction product is searched and acquired from the first transaction event on that date.TimeUntilTrading event informationthe aboveExtract from transaction event storageExtraction means to,For the extracted transaction event informationFor each priceDepending on the transaction typeAccumulate number of trading members and quantity over timeCumulative calculation means, and the number and quantity of trading members accumulated according to the transaction type for each price are shown in time seriesInformation board screen,Get aboveReproduction means for outputting both the display unit, which is an area for outputting information related to one piece of transaction event information performed immediately before the time, on the same screen;The first transaction event information is replaced with second transaction event information that is a transaction immediately before the first transaction event information, and the processing by the extraction means, the cumulative calculation means, and the reproduction means is executed. Updating the display on the board screen, and updating the display on the display unit to display information on the second transaction event information, and the first transaction event information on the first transaction event information. The display of the board screen is updated by executing processing by the extraction means, the cumulative calculation means, and the reproduction means in place of third transaction event information, which is a transaction immediately after one transaction event information, A post-event reproduction means for changing the display of the display unit to display of information relating to the third transaction event information;It is comprised so that it may have.
[0008]
  In such a transaction verification support system, an actual transaction screen is reproduced according to the specified date and time and the specified transaction product. Moreover, the last transaction event information according to the said date is displayed. Therefore, the transaction status up to the date and time and the transaction status at the date and time can be grasped. The screen showing the transaction status may be expressed in the same way as the actual status of stock buying and selling.Furthermore, it is possible to reproduce every one transaction event before or after every transaction event from the reproduced transaction status on the screen. Therefore, it can verify for every transaction event. Moreover, before and after the transaction status of the reproduced screen can be repeatedly reproduced as necessary.
[0009]
The transaction product indicates a stock brand, for example.
Each transaction event is a transaction process related to an order. For example, when an order is received and the order is executed, there are two transaction events related to the reception of the order: order reception processing and execution processing. In addition, when correcting the price specified in an already received order, there are two transaction events related to the correction of the order: a canceled order cancellation process and a corrected order re-acceptance process.
[0010]
The transaction event information indicates the content of the transaction event. For example, transaction event information indicating order reception by order reception, transaction event information indicating execution due to completion of a contract, or transaction event information due to correction of an accepted order. Each transaction event information includes date and time, transaction product (brand), member (securities company) identification, transaction type, quantity, price, and the like.
The designated date and time is a date and time designated before and after the date and time when significant information that fluctuates the stock price was released.
[0011]
From the viewpoint of reproducing the transaction status at the designated date and time, the present invention is the transaction verification support system according to claim 1, wherein the transaction event information includes a transaction type, a transaction member, The reproduction means includes a price list including information obtained by accumulating the number of trading members and the quantity of the extracted trading event information in time order according to the trading type for each price. Can be configured to be displayed.
[0012]
In such a transaction verification support system, a screen showing a transaction status can be reproduced by accumulating individual transaction event information up to a designated time.
The transaction type indicates the type of transaction event. For example, it indicates a sell order, a buy order, a contract or an order correction.
The number of trading members indicates the number of trade members that have fluctuated due to trading events. For example, when the number of members is increased by issuing an order, the number is indicated by a positive number. When the number of members is decreased by a contract, the number is indicated by a negative number. In the order correction transaction event, no increase or decrease in membership occurs, so zero is indicated. In the transaction event of order cancellation, the number of members is shown as a negative number.
[0013]
  The quantity indicates the order quantity that has fluctuated due to a trading event, like the number of trading members. For example, the quantity is shown in units of 1000 shares. The above price is a unit price. For example, the unit price of a stock is indicated. Further, from the viewpoint of displaying a breakdown of orders related to a specified price, the present invention claims2In the transaction verification support system according to claim 1, the screen of the screen reproduced by the reproduction means is described.GetThere is a designated price transaction display means to display the transaction event information indicating the order according to the price that was ordered in time orderRuConfigured as follows.
[0014]
  In such a transaction verification support system, transaction event information relating to a specified price can be displayed in time order. Therefore, it is possible to analyze the order status for each time which is difficult to understand from the screen showing the transaction status. In addition, if you display the breakdown of orders for the desired price,be able to.
[0015]
  MaIn addition, from the viewpoint of easily selecting a desired brand, the present invention claims3As described in claim 1Or 2In the transaction verification support system described,Acquisition aboveDateAndTimeEvery momentA transaction product list generation unit that generates a list of transaction products having a transaction event is configured to select a desired transaction product from the list.
[0016]
  In such a transaction verification support system, a desired brand can be selected from a list of brands traded at a specified date and time. Therefore, even if a large number of orders are generated, it is possible to narrow down the issues that need to be verified by specifying the date and time. In order to solve the second problem, the present invention claims4In the transaction verification support method that reproduces the screen showing the actual transaction status in order to verify the transaction event related to the order performed for each transaction product as described in the above, it is sampled for each transaction event related to the order.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The network which the transaction verification support system 100 which concerns on one Embodiment of this invention comprises is shown like FIG. 1, for example.
As shown in FIG. 1, the transaction verification support system 100 is installed on the TSE and is connected to each member (securities company) A to Z via a network.
[0019]
The transaction verification support system 100 installed in TSE and each member A to Z can refer to a board screen on which a sell order and a buy order are displayed according to the price for each brand. The member inputs a sell order or a buy order in which the price and the number of shares are specified from the board screen for each brand according to the order from the customer held by the member. The input information (member name, brand, order distinction indicating selling order or buying order, price, number of shares, etc.) is collected in the TSE transaction verification support system 100 via the network. The transaction verification support system 100 stores the information in a database and updates the board screen. The board screen is updated when an order is generated, when a price or the like is corrected, or when a value is determined and contracted by boarding, and the board screen of each member is updated immediately. The update information of these board screens is stored and accumulated in the database of the transaction verification support system 100.
[0020]
A hardware configuration of a computer system in which a transaction verification support system according to an embodiment of the present invention is configured is, for example, as shown in FIG.
2, this system includes a CPU (Central Processing Unit) 11, a memory unit 12, a communication unit 13, an input unit 14, a display unit 15, an auxiliary storage system 16, a CD-ROM drive unit 17, and a database (DB) 19. Have. Each of these units 11, 12, 13, 14, 15, 16, 17 and the database (DB) 19 are connected to the bus B.
[0021]
The CPU 11 controls the transaction verification support system according to the program stored in the memory unit 12 and performs processing in the transaction verification support system as described later. The memory unit 12 includes a RAM and a ROM, and stores programs executed by the CPU 11, data necessary for processing by the CPU 11, data obtained by processing by the CPU 11, and the like. A part of the memory unit 12 is allocated as a work area used for processing by the CPU 11.
[0022]
The communication unit 13 controls transmission and reception of information with each member in the transaction verification support system.
The input unit 14 includes a mouse, a keyboard, and the like, and is used for inputting various necessary information such as data input for performing plate reproduction processing as described later. The display unit 16 displays various information necessary for the user under the control of the CPU 11.
[0023]
The auxiliary storage system 16 is composed of, for example, a hard disk unit, and stores various files and programs.
The database 19 corresponds to the database shown in FIG. Transaction events related to orders from each member are stored and accumulated as records in a table managed in the database 19. Records stored and accumulated in the table of the database 19 are extracted and processed as necessary in plate reproduction processing described later.
[0024]
A program related to the plate reproduction process is provided to the system by, for example, the CD-ROM 50. That is, when the CD-ROM 50 storing the program related to the plate reproduction process is set in the CD-ROM drive unit 17, the CD-ROM drive unit 17 reads the program from the CD-ROM 50, and the read program is the bus. It is installed in the auxiliary storage system 16 via B. When this plate reproduction process is activated, the CPU 11 starts the process according to the program installed in the auxiliary storage system 16. The medium for storing the program is not limited to the CD-ROM 50, and any medium that can be read by a computer may be used.
[0025]
The board reproduction process executed by the CPU 11 in the transaction verification support system according to the embodiment of the present invention will be described with reference to FIGS. FIG. 3 is a flowchart showing a specified brand extraction process. FIG. 4 is a flowchart for explaining the plate reproduction process. FIG. 5 is a diagram illustrating screen transition. The screen diagram in FIG. 5 is a schematic diagram showing minimum information for convenience.
[0026]
For example, suppose a user verifies a stock traded at 9:10 on April 1, 1999.
In FIG. 3, in order to reproduce the past board screen, the user first causes the display unit 15 to display the order status screen 110 for each designated brand shown in FIG. 5 (step S11). Here, the user is a person who inspects whether there has been an illegal transaction in TSE. The user designates “1999/04/01” as the date designation 111 and designates the time “09:10” as the time designation 112 (step S12). Then, the CPU 11 creates a list by extracting all the brands of transactions performed at the relevant date and time from the database 19 using the designated date and time as a search key, and displays the order status screen 110 for each designated brand shown in FIG. The trading brand list 113 is displayed (step S13). The user further selects a brand that seems to be a specific transaction to be investigated from the trade brand list 113 shown in FIG. 5 (step S14). Since the user can select a brand from the trade brand list 113 narrowed down by the date designation and the time designation, the time required for the investigation for narrowing down the specific transaction can be shortened.
[0027]
When the specific transaction is selected, the CPU 11 displays the plate reproduction screen 120 shown in FIG. 5 on the display unit 15 according to the designated date, time, and brand (starts the plate reproduction process) (step S20).
Next, the plate reproduction process described above will be described with reference to FIG.
As shown in FIG. 4, the CPU 11 uses the stock code corresponding to the designated stock name on the date designated by the user from the database 19 in FIG. The board spool record stored in the above is retrieved, the board spool record indicating the first transaction event on the day is taken out to the board spool record closest to the specified time, and the board information is accumulated in time series (step S21). In the search of the board spool record, a table 200 as shown in FIG. 6 arranged in time series in a predetermined fixed time zone according to the designated date and designated time of the stock code is generated, and temporarily shown in FIG. It may be stored in the memory unit 12. By generating the table 200, the plate reproduction process can be performed efficiently.
[0028]
In the case of the above example, the date designation 121 and the time designation 122 on the board reproduction screen 120 in FIG. 5 display the values designated by the user in the date designation 111 and the time designation 112 on the order status screen 110 for each specified brand. . In addition, the brand name selected by the user from the trade brand list 113 on the order status screen 110 for each designated brand is displayed on the brand 123 on the plate reproduction screen 120. On the plate screen 127 of the plate reproduction screen 120, the information accumulated in step S21 is displayed as plate information (step S22). That is, the plate spool records up to just before 9:10 are accumulated, and the plate information up to the specified time is displayed. In the case of this example, two plate spool records of time “08:59:59” and time “09:00:00” in the table 200 of FIG. 6 are accumulated.
[0029]
Here, the plate spool record of FIG. 6 will be described. The board spool record is the time when a trading event such as an order occurs, the stock code, the trading category indicating a sell or buy order, the amount of increase or decrease in the number of unit shares increased or decreased due to the trading event such as an order, the price of the stock in that trading event Information such as a corresponding member code, a member number increased or decreased due to the transaction, and a corresponding code indicating a corresponding value of the price. The plate spool record is created and stored in the database 19 for each transaction event such as an order, a contract based on the order or price correction.
[0030]
The two plate spool records at time “08:59:59” and time “09:00:00” are both selling orders for the price “1020”. The number of members shown is added. Therefore, the displayed board information indicates that there has been a selling order of 2 unit shares in the cumulative quantity of 2 unit shares at the price “1020” from 2 members (2 members), and is displayed on the left half of the board screen 127. Is done. The units sold and accumulated are different for each brand, but usually 1000 shares are used as one unit. The board screen 127 displays the selling order on the left half and the buying order on the right half centered on the price.
[0031]
The member code and time in the board spool record at time “09:00:00” immediately before the specified time are extracted (step S23). In this case, the member code “025” (corresponding to member Y) and the time “09:00:00” of the board spool record at 9:00 are extracted.
A corresponding record is extracted from the order record using the retrieved member code and time as a search key (step S24). The order record is a record for recording a selling order and a buying order from each member. A table 300 as shown in FIG. 7 arranged in time series in a certain time period according to the specified date and time of the stock code may be generated and temporarily stored in the memory unit 12 of FIG. . By generating the table 300, the plate reproduction process can be performed efficiently. In this case, the order record at time “09:00:00” is extracted.
[0032]
The order information of the member Y immediately before the specified time from the extracted order record is displayed on the display unit 128 of the board reproduction screen 120 (step S25).
The user who is verifying the transaction of the brand name “M01” verifies the board information indicating the previous transaction event by clicking the rewind button 124 of the board reproduction screen 120 with the input unit 14 such as a mouse. be able to. When the user clicks on the rewind button 124, the CPU 11 takes out records up to the board spool record immediately before the board information displayed on the board screen 127 from the table 200 of FIG. 6 (steps S26 and S263). Further, the CPU 11 replaces the board spool record immediately before the designated time with the previous board spool record, and similarly performs steps S22, S23, S24 and S25, and accumulates the records up to the previous board spool record. The board screen 127 and the display unit 128 are updated.
[0033]
In addition, the user can verify the board information indicating the next transaction event by clicking the reproduction button 125 on the board reproduction screen 120 in the same manner as described above. When the user clicks the play button 125, the CPU 11 prohibits the previous board spool record from being taken out by determining “No” in the determination process of the rewind button in step S 26, and the CPU 11 is displayed on the board screen 127. The board spool record immediately after the board information is extracted from the table 200 of FIG. 6 (steps S27 and S273). Further, the CPU 11 replaces the board spool record immediately before the designated time with the next board spool record, and similarly performs steps S22, S23, S24 and S25, and accumulates the records up to the next board spool record. The board screen 127 and the display unit 128 are updated. As a result, since the actual transaction event can be reproduced on the board screen in the same situation as during the transaction, verification while comparing the transaction order as in the conventional case becomes unnecessary.
[0034]
Furthermore, when there are a plurality of members, the board screen 127 does not show the order breakdown such as which member has placed an order of how many shares, or whether the order by the same member has been made once or more than once. . In such a case, the user can verify the order status for each member by clicking the price portion of the plate screen 127 of the plate reproduction screen 120. When the user clicks on the price portion of the board screen 127, the CPU 11 prohibits taking out the previous board spool record by judging “No” in the judgment process of the rewind button in step S26, and in step S27. In step S30, the next button spool record is prohibited from being taken out by the determination of “No” in the playback button determination process, and the order status screen for the specified price is displayed. When the user clicks the price “1020” on the board screen 127, the CPU 11 extracts the order information corresponding to the price “1020” from the order record table 300 and the like, and the specified price order status as shown in FIG. The screen 130 is displayed on the display unit 15. In this case, there are two order records corresponding to the price “1020”, and each member “X” and “Y” indicates that there is a selling order of one unit stock. If there are two orders for the same member “Y”, it is indicated that there is an order of one unit stock at the same price “1020” at different order reception times. Further, when the sell order and the buy order are displayed at the price “1020” on the plate screen 127 of the plate reproduction screen 120, the selling category is distinguished from “sell” or “buy” on the designated price order status screen 130. Is displayed according to each order reception time. This specified price order status screen 130 can verify the order movement of the same member, the movement of the order between members, or the degree of variation or concentration of the order reception time. can do. Furthermore, since the displayed time is managed by the time that the computer has, even if the display time is the same in seconds, it is displayed in chronological order in μ seconds. You can analyze transactions. When the designated price order status screen 130 is finished by the user, the process of step S30 is finished.
[0035]
Further, when the user clicks the rewind button 124 or the playback button 125, the CPU 11 determines that the button clicked in step S29 is not the board reproduction end button, and again from step S26, the same as described above. Perform the following process.
The plate reproduction process shown in FIG. 4 is terminated when the user clicks on a plate reproduction end button, and the screen returns to the designated brand-specific order status screen 110 shown in FIG. When the user clicks the end button on the board screen, the CPU 11 ends the board reproduction process (step S20) shown in FIG. 3 and displays the order status screen 110 for each designated brand shown in FIG.
[0036]
In order to carry out another verification, when the user inputs a date specification or a time specification, the CPU 11 determines that the input is not an input for ending the verification (step S16). From step S12, the same processing as described above is repeated again. On the other hand, when the user clicks the end button for ending the specified brand extraction process, the CPU 11 ends the verification support for the user.
[0037]
When storing actual transaction events between members in the database 19, for example, for each transaction event, an order history table that stores data for each issue of a buy / sell order, a contract history table that stores contract information, and issued orders By classifying and storing in the correction history table or the like for storing correction information or cancellation information for the above, the processing in the above example is processed more effectively. For example, in the case of insider trading, the investor always observes the execution status of the issued order, and if the execution is not established, the investor tends to issue a cancellation order on the same day. Since it is possible to individually verify the issue status and correction status of orders, it is effective to verify an abnormally large number of orders for which no contract has been established. The table 200 is created with data extracted from the three tables. The table 300 is created mainly from data extracted from the order history table.
[0038]
Next, an example of verification support in the transaction verification support system according to the embodiment of the present invention in verification of an illegal transaction for which a promise has been established will be described with reference to FIGS. In FIG. 6, for convenience of explanation, supplementary explanations such as sale establishment or purchase establishment are given to some records of the table 200. Further, in FIG. 8, for convenience of explanation, numerical parts that are not particularly affected are indicated by lowercase letters h, m, n, x, and the like.
[0039]
A method of verifying the brand name “M01” when the news of a scandal relating to the brand name “M01” (brand code “001”) flows at 10:40 on April 1, 1999 will be described.
The user focuses on whether there was a special buy / sell order before the time when the news of the scandal flowed, and whether there was a buyback or resale that was unfairly profitable after that time. That is, first, in the same manner as described above, “1999/04/01” is designated as the date designation 111 on the order status screen 110 by designated brand in FIG. 5, and verification is performed from 10:40 before the scandal news flow. . For example, “10:30” is specified as the time specification. Next, the brand name “M01” is selected from the trading brand list 113 on the order status screen 110 for each designated brand. Then, the board reproduction screen 120 is displayed. The board screen 127 is updated with the button 124 or 125, and it is verified whether or not there is a large sales order to be noted. In the case of the example of the table 200 in FIG. 6, the user selects the member “Z” (member code “026”) immediately after 10:30 from the board reproduction screen 1201 corresponding to the example of the table 200 shown in FIG. Notice that the sell order tried to sell more shares. Furthermore, by clicking the play button 125 on the board reproduction screen 1201 in FIG. 8, the selling order of 980 yen for 6 shares of the member “Z” was successively filled with 3 members who priced 990 yen and 980 yen. I understand.
[0040]
When the user continues to click the play button 125, the member “Z” at 10:41 immediately after the news from the board reproduction screen 1202 shown in FIG. I notice that I am placing a buy order at a low price (950 yen). Further, by clicking the play button 125, it can be seen that other members who issued a selling order of 950 yen were contracted one after another at the same time as the order. In actual transactions, if the contract is executed immediately, the sell order and the buy order disappear from the board screen at the same time as the execution. However, such a situation can also be reproduced on a screen-by-screen basis by operating the buttons 124 and 125, so that it is possible to verify in detail the transaction trends of members who are thought to have been involved in unauthorized transactions.
[0041]
Since the user can narrow down the participating members by the verification by the above plate reproduction, it is only necessary to investigate whether the participating members actually gained profits. In this example, many members other than the member “Z” who has issued an order before and after the scandal news have confirmed the profit in the member “Z”, although the loss has been confirmed. Also, considering that the member “Z” issued sell and buy orders in a timely manner before and after the scandal news, and the contract was made almost exclusively, the stock trading conducted by the member “Z” The user determines that there is a high possibility that the transaction was fraudulent.
[0042]
By operating the above buttons 124 and 125 by the user, the information on the board screen can be displayed back and forth in chronological order, so that before and after a certain time can be reproduced as many times as necessary.
In addition, by reproducing the screens of the brands traded in the past desired by users in chronological order in computer time (μs), a large amount can be concentrated from multiple members according to the user's thoughts. Even when an order is generated, it is possible to display one screen at a time in units of microseconds. Therefore, details of members who seem to have been involved in fraudulent transactions even if transactions were made by many members at the same time. Can be verified.
[0043]
As described above, a large number of brands to be traded are narrowed down by date designation and time designation, and the user can easily select a desired brand from the narrowed brand list.
Also, by specifying the price of the board screen, it is possible to verify the movement of the order status at the specified price in time series. Therefore, when an excessively frequent transaction is performed at a specific price, it is possible to verify whether an unauthorized transaction has been performed by a specific member.
[0044]
In the above example, the processing in steps S21 and S22 shown in FIG.
[0045]

Further, according to the brand specified from the list, the transaction events up to the specified date and time are accumulated to reproduce the transaction status screen. Further, by specifying a price, transaction details regarding the price are displayed in time series. Therefore, by specifying the date and time, it is possible to narrow down the brands to be traded in large quantities, and to narrow the range of brands to be verified. Moreover, the transaction details can be verified by specifying the reproduction of the transaction status and the price.
[0046]
Further, according to the present invention described in claims 6 to 8, it is possible to provide transaction verification support for accumulating events that occur due to orders or the like up to a specified time, reproducing a transaction status at the specified time, and supporting verification of illegal transactions.
