Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(First embodiment)
FIG. 1 shows a stock trading system according to the first embodiment of the present invention. The trading system 100 has a trading terminal 110, a securities system 120 connected to the trading terminal 110 on the Internet, and a stock exchange system 130 directly or indirectly connected to the securities system 120.

The trading terminal 110 is, as shown in FIG. 1 , a mobile terminal such as a smart phone or a tablet, which includes a processing unit 111 such as a CPU, a communication unit 112 , and a storage unit 113 . A stock trading terminal having the functions described below is configured by executing a trading program (hereinafter referred to as "trading program") on the portable terminal.

Although not shown, the securities system 120 also includes a processing unit such as a CPU, a communication unit, and a storage unit, and can perform required functions by executing programs.

The stock exchange system 130 is a system for trading on domestic or foreign stock markets, and there are cases where a system of another securities company or the like intervenes between the stock exchange system 120 and the stock exchange system 130 .

FIG. 2 shows the flow of the trading method executed on the trading terminal. First, a list of stocks that can be traded is displayed on the display screen of the trading terminal 110 (S201). When the trading program is executed, the issues handled by securities system 120 are acquired, and at least some of them are displayed in a list (FIG. 3). In the example of FIG. 3, the list display is divided into 4 pages, and 3×3=9 brands are displayed on each page. In addition to 3×3, 3×2, 4×2, 4×3, 4×4, etc. are also possible. For example, in Japan, recommendation of specific stocks of less than 5 is regulated by association self-regulatory rules in the stock trading industry, so it is appropriate to set the number of stocks on each page to 5 or more. In addition to the matrix display example shown in Fig. 3, there are various ways of displaying the list, such as a list display. can do. This also removes the need for keyword searching by the user, allowing users with less knowledge required to search on their own to start trading stocks. The selection of brands to be handled can be performed based on, for example, being B2C. In the case of B2C, the product/service is widely used, has a high degree of recognition, and is highly motivated by users to purchase. This makes it possible to reduce the burden of stock selection.

Securities system 120 has an issue table that stores a list of issues handled. The issue table contains, for each issue, a unique code that uniquely identifies each issue, country code, market code (NASDAQ, TSE, etc.), issue code, issue name, last trading date, delisting date, trading suspension flag, settlement of accounts. The period, brand icon, etc. are included, and in the list display, the brand icon acquired from the brand table can be used for display. Here, the brand table is not limited to a single table, and may be composed of one or more tables.

When the user selects one of the displayed brands, a button for trading the selected brand is displayed on the trading terminal 110 (S202). In the example of FIG. 4, a "buy" button and a "sell" button are displayed, and it is possible to select whether to buy or sell the selected issue. Here, the user may be provided with information about the selected stock.

When the user expresses an intention to purchase or sell, the transaction amount (purchase amount or sale amount) is entered (S203). Here, the screen transitions to the transaction amount input screen after going through the screen requesting the intention to trade the selected issue (Fig. 4), but when the selection is made in the list of issues, the transition to the transaction amount input screen to reduce the number of user taps.

In the example of FIG. 5, a slot machine-like interface (also called a "picker") is displayed for specifying the purchase amount in units of 10,000 yen, and the user can specify the amount by rotating each digit. It can be carried out. The purchaseable amount of the user managed by the securities system 120 can be displayed on the transaction amount input screen. Each digit may not rotate further once it reaches the user's current purchaseable amount. For example, the strength of the input required to rotate may be increased as the purchaseable amount is approached, causing the rate of rotation to decrease. In the illustrated example, when the user further taps the "buy" button, the specified amount is confirmed, but the mode of confirmation is not limited to this. In addition, as shown in FIG. 5, the user's operability is remarkably improved by using an input screen for inputting only the designation of the amount as the interface, as compared with the conventional complicated input screen.

The entered transaction amount is then converted into a stock price and number of shares and displayed on the trading terminal 110 (S204). In the example of FIG. 6, based on the specified planned purchase amount of 10,000 yen, the number of shares is 0.94154 shares and the purchase price (stock price) is 88.09 dollars. Since the trading issues are foreign stocks, the exchange rate of 120.57 yen per dollar is also used here.

A stock price table that stores the stock price of each issue stored in the securities system 120 is referred to in calculating the stock price and the number of shares from the transaction amount. This stock price is determined by different methods depending on necessity when the stock market opens and when it closes.

The opening time can be determined using, for example, the market price when the transaction amount is determined or after the determination. The stock price itself may be used as the market price itself, and the user may pay a separate fee, but if the market price is used as a standard and a certain spread (price difference) is added or subtracted, the cost will exceed the transaction amount specified by the user. can be avoided. For example, when a customer buys shares of Google (registered trademark), the market price can be read in real time, and the market price plus a certain spread can be presented to the customer. On the other hand, when a customer sells a stock of Google, the market price can be read in real time and the customer can be presented with the market price minus a certain spread.

The closing time may be the closing price of the market or the price itself at the time of closing or before closing, or may be determined by adjusting the spread based on the price. At this time, the spread at the time of closing increases or decreases in light of the inventory status of the issue. Specifically, when the customer purchases, the inventory of the issue acquired through negotiated transactions in the securities system 120 decreases. Therefore, when the stock falls below a certain inventory standard, the spread is increased. By increasing , the supply and demand can be adjusted, and users can stably buy and sell in real time even when the market is closed.

The present invention is based on the premise that the operator of the securities system 120 acquires stocks of each issue and offers the purchase and sale of stocks to users through negotiated transactions. As a result, it is possible to offer low-value transactions such as 10,000 yen, which is below the minimum transaction amount in the market. The inventory status such as the number of shares held may be stored in the inventory table for each brand, or may be stored in the brand table.

After the amount designation is confirmed, the trading terminal 110 transmits a conversion request including the transaction amount to the securities system 120, and the securities system 120 refers to the stock price table to calculate the stock price and the number of shares corresponding to the transaction amount. The market prices stored in the stock price table and necessary for determining the stock prices may be real-time data obtained by receiving data distributed every second from the stock exchange system 130 at predetermined intervals of 3 seconds, 5 seconds, or the like. can. The calculated stock price and number of shares can be transmitted to the trading terminal 110 and output to the display screen as shown in FIG. The stock price table can be stored locally in the trading terminal 110, but by storing it in the securities system 120, the data can be kept up-to-date and the stock price at the time of opening can be calculated in real time. It is also possible to store the stock price table when the market is open in the trading terminal 110 and the stock price table when the market is closed in the securities system 120 .

In order to confirm the specified amount, as shown in FIG. 6, the user may be required to enter a passcode if necessary, and further, as shown in FIG. 7, the intention of the transaction may be confirmed again.

Under the calculated stock price and the number of shares, when the intention to trade is finally confirmed, the trading terminal 110 transmits a trade execution request for executing the trade to the securities system 120 (S205). The trade execution request includes the user identifier of the user of the trading terminal 110, the trading product, the stock price, and the number of shares, and may further include the trading amount. It is also possible to store the stock price and the number of shares calculated by the securities system 120, and execute the transaction with the stored stock price and the number of shares after the final confirmation of the user's intention to trade. The execution request contains the user identifier, the trade symbol, and optionally the trade amount, but doing so requires a large amount of data to be stored for trades that may not end up being executed. There is also a side that disappears.

When the transaction execution request is normally processed in the securities system 120, a display indicating that the order has been placed can be displayed on the trading terminal 110 as shown in FIG.

In the past, it was essential to specify the stock price and the number of shares on a PC website, which is assumed to be operated using 10 fingers on both hands, but in the trading method of this embodiment, the user should specify By narrowing down the parameter to the transaction amount such as the purchase amount or the sale amount, it is possible to input by intuitive graphical operation, which is one of the characteristics of mobile terminals such as smartphones and tablets, which are premised on one-finger operation. The user's input burden can be greatly reduced, and the base of stock trading can be expanded. In the past, it was necessary to specify both the stock price and the number of shares, which made it difficult to operate on a mobile terminal. Operation can be optimized.

Furthermore, as described above, by selecting the stocks to be handled in advance, it is possible to reduce the user's input burden, research burden, and the like.

(Second embodiment)
There are various aspects of graphically entering the transaction amount, examples of which are given below.

In FIG. 5, the slot machine-like interface is used, but it can also be, for example, a roulette-like interface.

Input as shown in FIG. 9 can also be performed. That is, by dragging an image such as an icon representing a brand to be traded and moving it to a predetermined position, the transaction amount associated with the predetermined position can be designated/input as the transaction amount of the brand. .

Further, as shown in FIG. 10, by dragging an image such as an icon representing an amount such as 10,000 yen or 100,000 yen to a predetermined position where an image imitating a ticket vending machine is arranged, It is possible to specify/input the transaction amount of the issue associated with the . The same is true for FIG. 11. In this example, by dragging and moving an image representing the amount to a predetermined position associated with the issue, the transaction amount for the issue is designated/input. By confirming the intention to trade, it is added to the user's portfolio list and displayed. As a form of displaying the portfolio, a pie chart may be used to show the ratio of each issue.

The interface can also be a shooting game, for example, by hitting an item such as an arrow representing an amount at a predetermined position, the transaction amount of the brand associated with the predetermined position can be obtained. Also, by hitting an item such as an arrow representing a brand at a predetermined position, the transaction amount associated with the predetermined position can be used as the transaction amount of the brand.

If it is necessary to specify the stock price and the number of stocks to be traded as in the past, such graphical operations are impossible or difficult, but as described in the first embodiment, refer to the stock price table according to the present invention. By calculating the stock price and the number of shares from the transaction amount, a variety of interfaces for unprecedented stock trading are possible.

The contents related to the present invention described above will be described in more detail below. FIG. 12 is a block diagram showing the internal configuration of the trading terminal 110 shown in FIG. As described above, the trading terminal 110 is a mobile terminal (user terminal) such as a smartphone or tablet, and this type of mobile terminal performs processing according to various functions by installing various programs (apps). It corresponds to a kind of computer. 1 only shows one trading terminal 110 in order to avoid complicating the illustration, but in the actual trading system 100, a plurality of trading terminals 110 are used according to the number of users. Therefore, these trading terminals 110 correspond to external terminals (external trading terminals) for the securities system 120 .

FIG. 12 shows the internal configuration when the trading terminal 110 is a smartphone. Devices are connected by an internal bus 110a. Even if the trading terminal is a tablet or a notebook personal computer (computer), the internal configuration basically conforms to that shown in FIG.

The communication unit 112 of the trading terminal 110 has a function of making a call to a predetermined telephone number (calling function) and a function of receiving a call (incoming call function) under the control of the processing unit 111, in addition to performing wireless communication processing via a network. etc. The RAM 114 temporarily stores contents, files, etc. associated with the processing of the processing unit 111 . The ROM 115 stores a program or the like defining basic processing contents of the processing unit 111, and also stores identification information (UID) or the like for identifying the smartphone. It should be noted that this UID is included in the content of transmission when communication (transmission) is performed by the communication unit 113 described above (for example, the UID is included in the header of a transmission packet and the like is transmitted).

The input/output unit 116 is connected to a display 118 having a touch panel function, and performs processing for outputting various screens (see screens shown in FIGS. 3 to 9, etc.) generated by the control processing of the processing unit 111 to the display 118. Then, the output screen contents are displayed on the display 118 . In addition, the input/output unit 116 also performs a process of sending operation details received by the user touching the surface of the display 118 to the processing unit 111, whereby the trading terminal 110 accepts various user operation details. . It should be noted that the content of the operation accepted by the user touching the surface of the display 118 changes as appropriate according to the content of the displayed screen.

The operation unit 117 is a hardware button provided on the housing of the trading terminal 110 , and when the operation unit 117 is operated, the processing unit 111 is notified of the operation. The meaning of the operation of the operation unit 117 varies depending on the processing status of the trading terminal 110. For example, when the operation unit 117 is operated while the application is running, the application is terminated. Therefore, in this case, the operation of the operation unit 117 is to receive an application termination instruction from the user. In the case of the present invention, since the stock trading application P2 for online stock trading (installed in the storage unit 113) is used, when the operation unit 117 is operated while the stock trading application P2 is running, When the trading terminal 110 receives the instruction to terminate the stock trading application P2, the logoff instruction of the stock trading application P2 is transmitted to the securities system 120 of the securities company.

The storage unit 113 stores (installs) programs such as the OS program P1, the stock trading application P2, and various other applications. The OS program P1 is a basic program corresponding to an operating system, and defines the processing of the processing unit 111 for the trading terminal 110 to function as a kind of computer. One of the basic processes defined by the OS program P1 is to first display the home screen on the display 118 when the trading terminal 110 is ready for use. Arrangement of icons and the like corresponding to various applications installed in the storage unit 113 is also based on processing defined by the OS program P1.

Stock trading application P2 stored in storage unit 113 is an application program (computer program) corresponding to an online stock trading service provided by securities system 120, and displays various screens for stock trading on display 118. It is stipulated that the processing unit 111 performs various controls according to the processing of transmitting various settings and trading instructions to the securities system 120 according to user operations on the screen. The processing unit 111 functions as various means such as performing processing for generating and displaying various screens. Note that the stock trading application P2 includes screen data corresponding to each screen part (buttons, etc.) for displaying various screens, in addition to the program code that defines the processing.

The stock trading application P2 is downloaded or acquired by the trading terminal 110 through a storage medium or the like, and installed in the storage unit 113 . When the installation is completed, a stock trading icon for starting the stock trading application P2 is arranged in a selectable manner in the home screen based on the OS program P1. When the trading terminal 110 accepts the user's operation to select the stock trading icon, and if it is already logged in at that time, the trading terminal 110 (processing unit 111) displays the brand list screen 12 shown in FIG. 14 on the display 118. , and if it is not in the login state, a process of generating a login screen (login screen 11 in FIG. 13) and displaying it on the display 118 is performed.

FIG. 13 shows an example of the login screen 11 displayed on the display 118, which is generated by the processing of the processing unit 111 based on the screen data for the login screen. The login screen 11 has an e-mail address (user ID) entry field 11a, a password entry field 11b, and a selectable login button 11c. The screen data for the login screen also includes the data of parts corresponding to each part arranged in this way. With the log-in screen 11 displayed, the soft keyboard 10 is displayed in the lower half of the screen by the function according to the processing defined by the OS program P1, and the user operates each key included in this soft keyboard 10. Then, predetermined contents are input to the respective input fields 11a and 11b. The password to be entered is determined for each user at the time of user registration for the stock trading service (see user DB 23 in FIG. 23, which will be described later).

When the trading terminal 110 accepts the selection operation of the login button 11c with the predetermined contents entered in the input fields 11a and 11b, the entered contents are forwarded to the securities system 120 as the user's login information. It is designed to be sent, and the data (data written in a script language, etc.) that defines such details is also included in the screen data for the login screen (selection operation is possible The contents related to buttons are the same for other screen data).

As will be described later, when the login information is sent to the securities system 120 and the login is completed, a login completion notification is sent to the trading terminal 110, and the information of the user who has completed the login and the stock price of each stock are sent. The information contained therein is sent from the securities system 120 to the trading terminal 110 that sent the login information. Information including stock prices and the like is transmitted (push transmission) to the trading terminal 110 . Even if the login information is sent to the securities system 120 , if the login is not completed due to a mismatch of the login information or the like, the securities system 120 sends a login failure notice to the trading terminal 110 . When the trading terminal 110 (processing unit 111) receives the log-in failure notification, the log-in screen (structurally equivalent to FIG. 13) indicating that the passwords do not match is displayed in order to secure an opportunity to enter again. ) is displayed on the display 118 .

A numerical value 4a of the amount of money that can be purchased is shown, and a full buy button 14a is arranged beside it so as to be selectable. Furthermore, the specific stock transaction screen 13 has an amount designation field 14b for the user to input and designate an arbitrary purchase amount below the purchaseable amount numerical value 4a and the buy all button 14a, and a buy button 14c below the amount designation field 14b. are arranged to be selectable.

As described above, the amount specification field 14b is a slot machine-like interface, and is designed so that the user can set the amount desired by the user. When the trading terminal 110 accepts the selection operation of the buy button 14c, the trading terminal 110 accepts the transaction amount (the amount set in the amount designation field 14b) by the user input, and the transaction amount input screen 14 is displayed. The transaction amount input screen 14 is designed so that a purchase request to buy the stock of the selected brand at the accepted transaction amount is transmitted from the trading terminal 110 to the securities system 120 (purchase transmitted to the securities system 120). The request contains information notifying the instrument, transaction amount, etc.). When the trading terminal 110 accepts the selection operation of the buy all button 14a regardless of the amount set in the amount designation field 14b, the amount (transaction amount) indicated by the purchasable amount numerical value 4a is entered. The transaction amount input screen 14 is designed so that a purchase request to buy the stock of the brand corresponding to the screen 14 is transmitted from the trading terminal 110 to the securities system 120 .

In addition, the transaction amount input screen 14 displays, below the above-described buy button 14c, a purchase price value 4b, a purchase exchange rate value 4c, an average acquisition price value 4d, an average acquisition exchange rate value 4e, and an increase in stock price. A numerical value 4f of rate, a numerical value 4g of rate of exchange rate increase, a numerical value 4h of investment principal, and a numerical value 4i of current appraisal value (profit and loss) are arranged. As these numerical values 4b to 4i and the purchasable amount numerical value 4a, the logged-in user information included in the information sent from the securities system 120 (total evaluation amount, investment principal amount, profit and loss etc.), and various information related to the selected issue (purchase price of the specific issue, purchase exchange rate, average acquisition price, average acquisition exchange rate, stock price increase rate, exchange rate increase rate, etc.) are used. When the stock market opens, information including the numerical values 4a to 4i is transmitted from the securities system 120 to the trading terminal 110 at any time. 4a to 4i are replaced with the latest ones, and the display is switched. Presentation of each of these numerical values 4a to 4i is used as material for the user's transaction decision (purchase decision).

FIG. 17 shows a passcode input screen 15 (corresponding to an identification information reception screen) capable of receiving an order passcode (corresponding to transaction identification information) input by the user, and the transaction amount input screen 14 in FIG. , the transaction terminal 110 accepts the selection operation of the buy button 14c with the transaction amount (10,000 yen in the illustration) set in the amount designation field 14b (equivalent to acceptance of the transaction amount). An example of a screen displayed on the display 118 is also shown (basically equivalent to the screen shown in FIG. 6).

In the passcode input screen 15, the brand name 5a (same as in FIG. 16) to be purchased is arranged at the top of the screen, and below it, the planned purchase amount column 15a, the number of shares column 15b, the purchase price column 15c, And, a purchase exchange rate column 15d is provided, and respective numerical values 6a to 6d are arranged in each column 15a to 15d.

The numerical value 6b of the number of shares included in the number-of-shares column 15b is transmitted to the securities system 120 by selecting the buy button 14c (or the buy all button 14a) on the transaction amount input screen 14 of FIG. This information is obtained by That is, when a purchase request including a transaction amount is sent to the securities system 120, the number of shares of a specific issue (selected issue) that can be purchased with that transaction amount will change to the real-time market price at that time, as will be described later. The number of shares is calculated by the securities system 120 based on the number of shares, and the calculated number of shares is included in the information transmitted from the securities system 120 to the trading terminal 110 . The trading terminal 110 extracts the number of shares included in the information from the securities system 120 and arranges it in the number of shares column 15b, and also receives the numerical values 6a, 6c, and 6d corresponding to the other columns 15a, 15c, and 15d from the securities system 120. It extracts from the transmitted information and arranges it appropriately.

Information including the numerical values 6a to 6d is transmitted from the securities system 120 as described above. Therefore, each time the trading terminal receives the transmitted information, it replaces the numerical values 6b to 6d in the columns 15b to 15d with the latest ones (the numerical values 6c and 6d in FIG. 17 are replaced by the numerical values 4b in FIG. 16). , 4c, but if the market price fluctuates at the time of screen switching, the displayed numerical values 6c and 6d will change from the numerical values 4b and 4c in FIG. Since the numerical value 6a in the planned purchase amount column 15a is input and set by the user, it is constant unless the input setting is changed.

The passcode input screen 15 has a passcode input field 15e arranged in the center in the vertical direction, and a soft keyboard 10 displayed below it, as in the case of the login screen 11 of FIG. ing. The passcode corresponds to identification information for trading when performing a transaction, and in this embodiment, a 4-digit number is used. , set by the user. An OK button 15f is selectably provided in the passcode input field 15e, and the trading terminal 110 accepts a selection operation of the OK button 15f in a state in which a predetermined four-digit numerical value is input in the passcode input field 15e. , the passcode input screen 15 is designed to transmit the accepted passcode (four-digit numerical value) to the securities system 120 .

The passcode entry field 15e is provided with a check box 15g for omitting passcode entry for users who wish to omit entry of the passcode from the next time. When the OK button 15f is selected in this state, the omission of the passcode input is stored in the storage unit 113 of the trading terminal 111, and the display of the passcode input screen 15 is omitted from the next time. is stipulated in the stock trading application P2, and the omission of passcode input is also sent to the securities system 120 by selecting the OK button 15f.

When the entered passcode is transmitted to the securities system 120, the securities system 120 returns either a passcode match notification or a passcode mismatch notification to the trading terminal 110, and the passcode does not match. When the trading terminal 110 receives the notification, the passcode input screen 15 is displayed on the display 118 to the effect that the passcode does not match and a re-input is requested. Each numerical value 6b to 6d included in the passcode input screen 15 displayed when the passcode does not match is the latest in real time at the time of display.

In addition, when the passcode input screen 15 is displayed, the trading terminal 110 performs processing for measuring the display time of the passcode input screen 15 using a timer function provided in the processing unit 111 . Then, the processing unit 111 compares the reference time (fixed time) set in the stock trading application P2 with the timed display time. As a result of the comparison, if the timed display time exceeds the reference time, timeout As such, the processing unit 111 performs processing (timeout processing) for switching the display screen of the display 118 from the passcode input screen 15 to the transaction amount input screen 14 shown in FIG. The introduction of this kind of timeout processing causes confusion for users because the stock price and the calculated number of shares, which are trading conditions, change with market price fluctuations, and frequent changes in trading conditions cause confusion for users. is done with the aim of avoiding It should be noted that when executing the timeout process, the trading terminal 110 transmits a timeout (exceeded time) notification to the securities system 120 .

As the reference time for timeout processing, considering that the display of each numerical value 6b to 6d is maintained constant, the securities system 120 determines the market prices of a plurality of stocks to be traded distributed from the stock exchange system 130. It is set to about 3 to 5 seconds to acquire (preferably about 4 to 5 seconds considering the passcode input time). However, if you want to secure a longer passcode input time, or if you think that each numerical value 6b to 6d can be switched as appropriate, it is possible to set a longer time than 5 seconds (for example, 6 up to about 8 seconds), and the reference time may be appropriately set on a menu screen or the like according to user convenience.

FIG. 18 shows an intention confirmation screen 16 (equivalent to the screen shown in FIG. 7) for confirming the intention of a transaction (for example, purchase) from the user, and there are two display situations. The first display state is the display on the display 118 when the trading terminal 110 receives a passcode match notification from the securities system 120 . As a second display state, when the fact that the password entry is omitted is stored in the storage unit 113, it means that the transaction amount has been accepted by the selection operation of the buy button 14c on the transaction amount input screen 14 of FIG. This is also the case when it is displayed on the display 118 .

The intention confirmation screen 16 has a configuration in which the passcode input field 15e in the middle of the passcode input screen 15 shown in FIG. 17 is replaced with a confirmation field 16e. Similar to the other input screen 15, a brand name 8a, an expected purchase amount column 16a, a number of shares column 16b, a purchase price column 16c, and a purchase exchange rate column 16d are provided at the top of the screen. Numerical values 7a to 7d are arranged. The numerical values 7b to 7d arranged in the columns 16b to 16d are the latest ones transmitted from the securities system 120 at the time the intention confirmation screen 16 is displayed (numerical values 7b to 7d in FIG. 18). shows the same example as the numerical values 6b to 6c in FIG. 17, but if the market price fluctuates at the time of screen switching, the displayed numerical values 7b to 7d will change to the numerical values 6b to 6c).

In addition, the confirmation column 16e of the intention confirmation screen 16 has a quit button 16f and a buy button 16g selectably. When the selection operation of the stop button 16f is received, the trading terminal 110 performs a process of switching the display screen of the display 118 from the intention confirmation screen 16 to the transaction amount input screen 14 shown in FIG. On the other hand, when the selection operation of the buy button 16g is accepted, the trading terminal 110 purchases the brand stock of the brand name 8a based on the conditions of the numerical value 7c indicated in the purchase price column 16c. 7a to the securities system 120 (the transaction execution request includes the number of shares of the number 7b in the number of shares column 16b).

In addition, as will be described later, when the securities system 120 receives a transaction execution request from the trading terminal 110, according to the transaction execution request, the stock of the selected issue (the stock of the issue name 8a) is traded in a negotiated transaction, When transaction processing is completed, a transaction completion notice is sent to the trading terminal 110 .

In addition, the trading terminal 110 also introduces a timeout process for the display of the intention confirmation screen 16, as in the case of the passcode input screen 15 described above. Processing for measuring the display time of the confirmation screen 16 is performed by a timer function of the processing unit 111 . Then, the processing unit 111 compares the reference time (fixed time) with the measured display time. The processing unit 111 performs processing (timeout processing) for switching from the confirmation screen 16 to the transaction amount input screen 14 shown in FIG.

FIG. 19 shows the order execution screen 17, which is displayed on the display 118 when the trading terminal 110 receives a transaction completion notice from the securities system 120. FIG. In the order completion screen 17, the brand name 17a for which the transaction has been completed is arranged at the top, and a purchase amount column 17b is provided slightly below the center in the vertical direction to indicate the numerical value 17c of the transaction amount. , indicates that the ordered transaction has been completed. By displaying the order completion screen 17, the user can confirm that his/her order transaction has been completed. From the display state of the order completion screen 17, various processes based on the function of the OS program P1 (for example, a process to return to the home screen, a process to return to the state in which the application is started) can be performed as appropriate to restore the trading terminal 110. It is possible to shift to a state desired by the user.

Also, in the above description, the transaction for buying has been described, but the screen transition for selling is basically the same as in the above case. That is, when the trading terminal 110 accepts the selection operation of the sell button 13c on the selected issue screen 13 shown in FIG. When the selection operation of this replaced sell button is received, a sale request for the amount set in the amount setting column (equivalent to the amount specifying column 14b in FIG. 16) is traded to the securities system 120. Terminal 110 transmits.

The upper limit of the amount that can be set in the amount setting field is the appraisal value of the stock owned by the user for the trading issue (selected issue), and such an appraisal value is included in the information sent from the securities system 120 The trading terminal 110 sets the valuation price included in the received information to the upper limit of the price range that can be set in the price setting column. In addition, in the process of selling, the transaction amount input screen 14 shown in FIG. The value 4c of the attached exchange rate is changed to the value of the sales exchange rate, etc., and these sales values are also included in the information sent from the securities system 120. FIG.

In the process of selling, the passcode input screen 15 shown in FIG. 17 basically has the same screen configuration. , the sales price set by the user is placed in the numerical value 6a, and the purchase price column 15c and the purchase exchange rate column 15d are also changed to the sale price column and the sale exchange rate column. The numerical value related to the sale will be arranged according to the

Furthermore, in the process of selling, the intent confirmation screen 16 shown in FIG. 18 is basically of the same screen configuration. The planned price column 16a is changed to the planned sale price column, and the numerical value 7a of the planned sale price column is also set by the user. It will be changed to the exchange rate column, and the numerical value related to the sale will be arranged in the changed column.

Furthermore, in the process of selling, the order establishment screen 17 shown in FIG. The column is changed to the sales price column, and a numerical value corresponding to the sales price corresponding to the changed column is arranged.

FIG. 20 is a block diagram showing the main internal configuration of securities system 120. As shown in FIG. The securities system 120 of this embodiment is configured by a general-purpose server computer as hardware. By installing a trading program P11 (computer program for server) that defines various characteristic processing of the present invention in this server computer, the stock of the brand selected by the user can be traded through negotiated trading with a designated amount. The server computer functions as a trading securities system 120 that performs Although only one server computer is shown in FIG. 20, the securities system 120 is configured by combining a plurality of server computers, database systems, etc., for example, by performing distributed processing for various processes performed by the securities system 120. You may Note that the securities system 120 (stock trading server) corresponds to an external system (external securities system) from the trading terminal 110 described above.

A server computer (server device) that constitutes the system 120 in this embodiment is an MPU 120a that performs overall control and various processes, and various devices and the like are connected via internal connection lines 120h. includes a communication module 120b, a RAM 120c, a ROM 120d, an input interface section 120e, an output interface section 120f, a mass storage system (HDD system) 120g, and the like.

The communication module 120b is a communication device (communication means) corresponding to a connection module with a network, and conforms to required communication standards (for example, a LAN module). The communication module 120b is connected to a network (an internal network of the securities system 120 or an external network) via a required communication device (not shown; for example, a router or the like). , and with the stock exchange system 130 and the like.

The RAM 120c temporarily stores the contents, files, etc. associated with the processing of the MPU 120a, and the ROM 120d stores programs and the like defining basic processing contents of the MPU 120a. The input interface unit 120e is connected to a keyboard 120i and a mouse for receiving operation instructions from the system administrator of the securities system 120, and transmits the operation instructions received from the system administrator to the MPU 120a. The output interface unit 120f is connected to a display 120j (display output device), and outputs the contents accompanying the processing of the MPU 120a to the display 120j so that the system administrator can confirm the current processing contents. there is

A large-capacity storage system 120g (corresponding to storage medium means) stores programs, a database (DB), etc. In this embodiment, a system program P10, a trading program P11, a brand table 20, a brand DB 21, and a stock price table 22 are stored. , a user DB 23, a user account DB 24, a user-owned brand DB 25, an exchange table 26, a stock price information table 27, and the like.

The system program P10 prescribes various kinds of processing according to the operating system for the server, and the securities system 120 performs the basic functions as a server computer by the MPU 120a executing the processing based on the content of the stipulations. Fulfill. The trading program P11 will be described later. As described above, the issue table 20 includes unique codes, country codes, market codes, issue codes, issue names, last trading dates, delisting dates, trading suspension flags, accounting periods, issue icons, etc. for multiple stock issues. It has become a thing.

FIG. 21 shows an overview of the contents of the brand DB 21. As shown in FIG. The brand DB 21 stores (inventory) the stocks of each brand that are acquired in advance and stocked by the securities system 120 for bilateral trading. As described above, the securities company associated with the securities system 120 purchases (acquires) the required number of stocks of the stocks to be traded and stocks them in order to conduct negotiated transactions. is stored in the brand DB 21. Specifically, numerical values corresponding to the total number of stocks, user purchases, and the number of stocks are stored for each brand. The total number of shares in stock indicates the total number of stocks, the number of user purchases indicates the number of shares purchased by the user out of the total number of stocks, and the number of stocks in stock indicates the number of shares purchased by the user in the total number of stocks. indicates the number of outstanding shares (remaining). The numerical values stored in the stock DB 21 are updated as needed due to purchase processing by the user, new stock purchases by securities companies for new stock, and sales of stock (including user purchases) to the trading market. be done.

FIG. 22 shows an overview of the contents of the stock price table 22. As shown in FIG. The stock price table 22 sequentially stores stock prices (market prices) of a plurality of stocks included in the information distributed from the stock exchange system 130 in association with the date and time of reception. The MPU 120a (securities system 120) uses the communication module 120b to receive information distributed as needed from the stock exchange system 130 at intervals of seconds, extract the stock price of each brand included in the received information, and A process of storing in the stock price table 22 in the capacity storage system 120g is performed. It should be noted that such memory processing is performed on a day-by-day basis.

That is, the stock price table 22 has columns for each brand such as a column for each stock brand (for example, A company stock column 22a, B company stock column 22b, C company stock column 22c, etc.) in the left column. The rows form a grid table having date columns (for example, column 22x for June 27, 2016, column 22y for June 28, column 22z for June 29, etc.).

As described above, the stock exchange system 130 distributes information including the latest stock price of each issue every second, and the stock exchange system 120 distributes The stock price of each brand is obtained from the information received (the information is obtained several times a day), and the obtained stock price information is stored in the column corresponding to each brand in the column of the date of acquisition in the stock price table 22. Then, a process of sequentially storing the acquired time is performed. With this process, for example, in the column 22a of Company A stock in the column 22x on June 27, 2016, each acquisition from the stock price (opening price) at 9:00 to 15:00 (closing price) The stock price at the time is accumulated. The stock price table 22 in FIG. 4 shows the situation as of 13:28:19 on June 28, 2016. Therefore, the latest acquisition time in the column 22y on June 28 is 13:00. The time is 28 minutes and 19 seconds, and the column 22z and subsequent columns for June 28 are blank. Even after this latest time, the contents of the stock price table 22 are updated at any time as the latest stock prices are acquired. go. Since the acquired stock prices are accumulated in the stock price table 22, the stock prices (market prices) before or after the market is closed are also stored in the stock price table 22. The date columns 22x, 22y, etc. store opening and closing stock prices, and the closing stock price is referred to as the stock price at the time the market is closed.

FIG. 23 shows an overview of the contents of the user DB 23. As shown in FIG. The user DB 23 is a database that stores various information about users who have registered with an online stock trading service provided by a securities company that operates the securities system 120 and opened trading accounts. A user ID for identifying a user is given to each user by the securities system 120 (securities company), and the user DB 23 stores various information in association with the given user ID. Specifically, the user DB 23 stores, for each user (user ID), the user's name, address, telephone number, email address, UID (identification information of the trading terminal used by the user), occupation, password, passcode, passcode input It remembers whether or not it is necessary. In this embodiment, the registered e-mail address is used as the login ID at the time of login, and the passcode uses 4-digit numerical information set by the user himself at the time of user registration.

FIG. 24 shows an overview of the contents of the user account DB 24 stored in the mass storage system 120g described above. The user account DB 24 is a collection of user account tables 900, 901, 902, etc. that store account information on user accounts (trading accounts used for trading at securities companies) for each registered user (user ID). A user (investor) deposits a required amount of money into this user account, and applies the deposit to the cost of purchasing stocks. In addition, the amount obtained by the sale of the owned shares by the user will also be credited to the user account.

FIG. 25 shows an overview of the contents of a user account table 900 with a user ID of 0100 as an example of the user account table stored in the user account DB 24. FIG. The user account table 900 contains the latest balance (deposit amount) of the user account of the registered user, the investment principal, and the history of stock trading transactions (amount and date used for stock purchase, amount and date obtained by selling stock, etc.). ) is stored. Therefore, the user account DB 24 includes the above-described user account table for each user so that the securities system 120 can grasp the account information (deposit information) for each user (user ID).

Also, FIG. 26 shows an overview of the contents of the user-owned brand DB 25 stored in the mass storage system 120g. The user-owned brand DB 25 stores, for each user (user ID), the owned stock brand owned by each user, the number of stocks currently owned, the history of the number of stocks owned, and the like. As a result, the securities system 120 (securities company) or the like grasps the stock brands owned by each user and the information associated with the trading process thereof, and provides them to the users.

The exchange table 26 stored in the large-capacity storage system 120g shown in FIG. Acquired exchange information is accumulated. This external exchange information distribution system also distributes the latest exchange information every second, and the securities system 120 also sequentially acquires the exchange information distributed as needed and accumulates it in the exchange table 26 . The exchange information to be distributed includes the exchange rate (dollar-yen exchange rate), the average exchange rate for the required period, the rate of increase in the exchange rate (change rate relative to the previous day's value), and the like.

The stock price information table 27 stored in the large-capacity storage system 120g shown in FIG. 2 can sequentially receive and store the information arbitrarily distributed from the stock exchange system 130 described above. The information delivered from the stock exchange system 130 includes the stock price (market price) of each issue, the average stock price (average market price) of each issue during a predetermined period, the rate of increase of each issue (the rate of change relative to the previous day's price) ) etc. are included.

Next, the processing contents defined by the transaction program P11 stored in the large-capacity storage system 120g in the securities system 120 will be described. The transaction program P11 of the present embodiment is installed in the mass storage system 120g via a storage medium such as an optical disc, and defines various control processes to be executed by the MPU 120a regarding user login, sales transactions, and the like. As a result, the MPU 120a functions as various means.

First, regarding the user's login, when the communication module 120b receives the user's login information (user's email address, password, user terminal's UID, etc.) transmitted from the trading terminal 110 (user terminal), the received login information The transaction program P11 prescribes that the MPU 120a performs a process (login process) for determining whether matching information is stored in the user DB 23 of FIG.

If it is determined that the received login information (user login information) is not stored in the user DB 23, the communication module 120b is used to transmit login disapproval information indicating that the login information does not match to the trading terminal 110 that sent the login information. The transaction program P11 prescribes that the MPU 120a controls the transaction. On the other hand, if it is determined that the received login information is stored in the user DB 23, the login is completed for the user ID corresponding to the login information, and the user ID is set to the logged-in state. The MPU 120a stores the login status information indicating that login has been completed in the RAM 120c or the like, and transmits the login completion information indicating that the login has been completed to the trading terminal 110 of the user who has completed login. The login status information is stored together with the user ID in the RAM 120c until logoff information is received from the trading terminal.

After logging in, the user can use the services provided by the securities system 120, and can perform the trading process of the stock brand desired by the user, various settings, and the like. In addition, the securities system 120 appropriately transmits information of logged-in users to the trading terminals 110 that have completed logging in, and also starts processing of transmitting information including the stock price of each issue at any time.

Then, when a purchase instruction for a selected issue (for example, Facebook (registered trademark)) is sent from the trading terminal 110 of the logged-in user, the securities system 120 receives the purchase instruction from the stock price table 22. Identify the stock price (market price) of the selected stock that is the latest at the time, and from the exchange table 26, identify the latest exchange rate, average exchange rate, rate of increase in exchange rate, etc. at the time of receiving the purchase instruction. Then, from the stock price information table 27, the average stock price (average market price) of the selected stock, the stock price increase rate, etc. are specified, and the balance (purchasable amount) is specified from the user account table of the logged-in user ), the investment principal, etc. are specified, and the current appraisal value (profit and loss) for all brands owned by the user from the specified investment principal is calculated from the latest stock price of each brand included in the stock price table 22. , and transmits the specified various information to the trading terminal 110 of the logged-in user. Since the market price etc. fluctuates from time to time, the various information specified in this manner should be specified and transmitted to the trading terminal 110 when the latest market price is stored in the stock price table 22. , securities system 120 repeats.

Thereafter, when a purchase request for the selected issue is transmitted from the trading terminal of the logged-in user, the latest market price of the selected issue at the time of receiving the purchase request is specified from the stock price table 22 and specified. The market price obtained is the real-time price. Then, the stock system calculates the number of shares to be purchased with the transaction amount included in the received purchase request based on the specified real-time market price by referring to the latest exchange rate stored in the exchange table 26. 120 does. The securities system 120 performs a process of transmitting the calculated number of shares and the various types of information described above to the logged-in trading terminal 110 .

In addition, the securities system 120 confirms whether or not the user who is logged in needs to enter a passcode in the user DB 23, and if the passcode input is not omitted, the passcode sent from the trading terminal of the logged-in user is entered. matches the passcode of the logged-in user by comparing the passcode stored in the user DB 23 with the received passcode. When determining that the passcodes match, the securities system 120 transmits a passcode matching notification to the trading terminal of the logged-in user, and transmits a passcode mismatch notification when determining that the passcodes do not match. When a passcode mismatch notification is sent, it is determined again whether the passcode needs to be entered. If the securities system 120 receives a timeout notification from the trading terminal of the logged-in user before receiving the passcode, the securities system 120 returns to the state of determining whether or not the purchase instruction has been received.

Then, when the securities system 120 transmits the passcode match notification, it identifies the latest market price of the selected issue from the stock price table 22 at the time of transmitting the notification, and the identified market price is Using the real-time price as the real-time price, the number of shares to be purchased with the transaction amount included in the purchase request is calculated with reference to the latest exchange rate at this time from the exchange table 26 for the above-mentioned real-time market price. The securities system 120 performs processing to transmit the calculated number of shares and the various information described above to the logged-in trading terminal 110 .

As described above, when the security system 120 receives a time-out notification even after calculating the number of shares in accordance with the transmission of the passcode matching notification, it returns to the state of determining whether or not the purchase instruction has been received. . Then, when receiving the transaction request execution, the securities system 120 executes a process of purchasing the most recently transmitted number of shares (the number of shares of the stock of the selected issue) in a negotiated transaction. When the processing is completed, the securities system 120 transmits a transaction completion notice to the trading terminal 110 of the logged-in user, and stores the details of the transaction processing in the user account table of the logged-in user and the user-owned issue DB 25. conduct.

The contents of the processing of the securities system 120 according to the provisions of the trading program P11 have been described as a case of buying stocks as a transaction, but the processing of selling stocks only changes the contents of the above-mentioned purchase to the contents of selling. , the basic processing is the same as when buying. In addition, the above explanation was given when the stock market was open, but when the stock market was closed, the latest market price stored in the stock price table 22 ( (market price) or the value immediately before the closing price (market price corresponding to before the market closes) is used.

Next, a series of processing contents related to the stock trading method of the stock trading system of the present invention by the trading terminal 110 and securities system 120 having the above-described configuration will be described based on the first to third flow charts of FIGS. 27 to 29 ( The stock trading system defined in the present invention is a system composed of the trading terminal 100 and the securities system 120, and the stock exchange system 100 shown in FIG. 1 is included in the stock trading system of the present invention as an external system. not). Further, the processing performed by the trading terminal 110 in the first to third flowcharts corresponds to the stock trading method by the trading terminal 110, and the processing performed by the securities system 120 in the first to third flowcharts corresponds to the stock trading method by the securities system 120. correspond to

The first to third flow charts start from the stage of displaying the brand list screen 12 of FIG. The contents are according to Although not shown in each flowchart, upon completion of login, the securities system 120 transmits information on the logged-in user and information on multiple stocks to be traded to the trading terminal 110 at any time. and

First, as shown in the first flowchart of FIG. 27, the trading terminal 110 displays the brand list screen 12 (see FIG. 14) on the display 118 (S1). Then, the trading terminal 110 determines whether or not any of the brand icons 12a to 12i arranged in the brand list screen 12 has been selected by the user's operation and selection of the brand has been received (S2). If the selection of the issue has not been accepted (S2: NO), it will be in a state of waiting for selection, and if the selection of the issue has been accepted (S2: YES), the trading terminal will display the selected issue screen as the screen for the issue for which the selection has been accepted. 13 (see FIG. 15) is displayed (S3).

On the selected issue screen 13, the trading terminal 110 determines whether or not the selection operation of the buy button 13b has been accepted (S4), and if the buy button 13b has not been selected (S4: NO), the trading terminal 110 waits for selection. , and when the selection of the buy button 13b is received (S4: YES), an instruction to purchase the selected issue is transmitted to the securities system 120 (S5). Since the purchase instruction includes information indicating the selected issue, the selected issue selected by the user is transmitted to the securities system 120 .

On the other hand, securities system 120 is in a state of judging whether or not a purchase instruction has been received from a logged-in user (S10). When a purchase instruction is received (S10: YES), in addition to the information sent as needed (stock price of each brand, information on exchange rates, etc.), the current (latest at that time) evaluation of the logged-in user In addition to calculating the amount and transmitting it to the trading terminal 110, the market price, average stock price, stock price increase rate, etc. are transmitted as the latest information (most recent information at the time of receiving the purchase instruction) for the selected issue ( S11). In addition, the securities system 120 transmits the most recent information (latest information) to the trading terminal 110 at any time in order to present the user with the fluctuation of the value due to the market price even after the various information sent at the stage of S11. .

When the purchase button 13b is selected, the trading terminal 110 transmits a purchase instruction as described above, and also changes the display screen of the display 118 from the selected issue screen 13 to the transaction amount input screen 14 (see FIG. 16). (S6). On the transaction amount input screen 14 displayed in this manner, numerical values 4a to 4i included in the information transmitted from the securities system 120 are arranged. Up-to-date information from 120 may change the values.

With the transaction amount input screen 14 displayed, the trading terminal 110 determines whether or not the transaction amount has been input and set, and the selection of the buy button 14c has been accepted (S7). If the buy button 14c has not been selected (S7: NO), the state waits for the selection of the buy button 14c. The trading terminal 110 transmits a purchase request (which may include a logged-in user ID, etc.) including the selected issue and the like to the securities system 120 (S8).

The securities system 120 determines whether or not a purchase request has been received from the trading terminal 110 (S12). will continue to send. Also, when a purchase request including transaction amount etc. is received (S12: YES), the most recent (latest) market price of the selected issue at the time of receiving the purchase request is identified from the stock price table 22 as the real-time market price. Then, based on the specified market price, the number of shares of the selected issue when trading with the transaction amount included in the received purchase request is calculated by referring to the exchange rate at the time of receiving the purchase request from the exchange table 26. (S13). The securities system 120 then transmits the calculated number of shares to the trading terminal 110 (S14). At this stage as well, the securities system 120 continues to transmit the latest various information that started to be transmitted at the stage of S11.

In the second flowchart of FIG. 28 , when the trading terminal 110 accepts the selection of the buy button 14c on the transaction amount input screen 14 of FIG. By confirming whether or not the omission of code entry is stored, it is determined whether or not the passcode entry is required (S20). If the password input omission is set (S20: YES), the processing of the trading terminal 110 proceeds to step S40 in the third flow chart of FIG.

In addition, if omission of passcode input is not set (S20: NO), the trading terminal 110 switches the screen display of the display 118 from the transaction input screen 14 to the passcode input screen 15 (see FIG. 17) (S21 ). By displaying the passcode input screen 15, the number of shares based on the real-time market price calculated by the securities system 120 is also displayed on the display 118 (see numerical value 6b in FIG. 17). Then, when the passcode input screen 15 is displayed, the trading terminal 110 measures the display time of the screen (S22), and sets the measured time to the reference time (fixed time) set in the stock trading application P2. , it is determined whether or not the reference time has exceeded (S23).

If the reference time has passed (S23: YES), the trading terminal 110 transmits a timeout notification to the securities system 120 (S24), returns to step S6 of the first flow chart, and displays the display screen of the display 118. The code input screen 15 is switched to the transaction amount input screen 14.

If the reference time has not passed (S23: NO), the trading terminal 110 determines whether or not the passcode input has been received (S25), and if the passcode input has not been received (S25 : NO), the process returns to step S22, and the trading terminal 110 continues clocking. When the passcode is entered and the OK button 15f is selected and the passcode input is accepted (S25: YES), the trading terminal 110 transmits the accepted passcode to the securities system 120 (S26). .

After transmitting the number of shares at the stage of S14 in the first flowchart, the securities system 120 next refers to the user DB 23 for the logged-in user to determine whether or not the input of the passcode has been omitted. If yes (S30) and the input of the passcode is omitted (S30: YES), the processing of the securities system 120 proceeds to step S50 in the third flow chart of FIG.

If the input of the passcode has not been omitted (S30: NO), the securities system 120 determines whether or not the passcode sent from the trading terminal 110 has been received (S31). If the passcode has not been received (S31: NO), the securities system 120 next determines whether or not a timeout notification has been received from the trading terminal 110 (S32), and has received the timeout notification. If not (S32: NO), the process returns to the step of S31 to determine whether the passcode has been received. Also, when a timeout notification is received (S32: YES), the processing of the securities system 120 returns to the stage of S11 in the first flow chart, and various information is transmitted to the trading system 110. FIG.

When the passcode is received from the trading terminal 110 (S31: YES), the security system 120 checks whether the received passcode matches the passcode corresponding to the logged-in user. The stored contents of the DB 23 are referred to and judged (S33). If the received passcodes match (S33: YES), the securities system 120 transmits a passcode match notification to the trading terminal 110 (S34), and proceeds to step S50 in the third flow chart. On the other hand, if the received passcodes do not match (S33: NO), the securities system 120 transmits a passcode mismatch notification to the trading terminal 110 (S35), and returns the processing of the securities system 120 to step S31. Become.

After transmitting the passcode in step S26, the trading terminal 110 determines whether to receive a passcode match notification or a passcode mismatch notification from the securities system 120 (S27). If received (S27: mismatch), the process returns to step S21 and the passcode input screen 15 is displayed. Please fill in." can be added. Also, when the passcode match notification is received (S27: match), the processing of the trading terminal 110 proceeds to the third flow chart.

In the third flowchart of FIG. 29, first, the securities system 120 identifies the most recent (latest) market price of the traded issue at the time of receiving the passcode from the stock price table 22 as the real-time market price, and Based on the specified market price, the number of shares of the selected issue when trading with the transaction amount included in the previously received purchase request is calculated by referring to the exchange rate at the time the passcode is received from the exchange table 26 (S50 ). The securities system 120 then transmits the calculated number of shares to the trading terminal 110 (S51). At this stage as well, the securities system 120 continues to transmit the latest various information that started to be transmitted at the stage of S11. If the passcode input is omitted, the processes in steps S50 and S51 are performed following the calculation of the number of shares in S13 and the transmission of the number of shares in S14 in the first flow chart. If there is not, the processing of steps S50 and S51 may be integrated into the processing of S13 and S14.

If the passcode input is not omitted, the trading terminal 110 receives the passcode matching notification along with the passcode transmission, and changes the display screen of the display 118 from the passcode input screen 15 to the intention confirmation screen 16 (Fig. 18) (S40). In displaying the intention confirmation screen 16, the trading terminal 110 receives various information including the latest number of shares calculated at the stage of S50 from the securities system 120. Therefore, each numerical value 7b included in the intention confirmation screen 16 ˜7d are also the most recent real-time values arranged, and the number of stocks based on the real-time market price calculated by the securities system 120 is also displayed on the display 118 (see numerical value 7b in FIG. 18). If the passcode input is omitted, the intention confirmation screen 16 will be displayed on the display 118 of the trading terminal 110 when the transaction amount is accepted on the transaction amount input screen 14 of FIG. (See S20: YES in the second flow chart).

When the intention confirmation screen 16 is displayed, the trading terminal 110 measures the display time of the intention confirmation screen 16 (S41), and It is judged whether or not the reference time has passed by comparing with the reference time (fixed time) set in the stock trading application P2 (S42).

If the reference time has passed (S42: YES), the trading terminal 110 transmits a timeout notification to the securities system 120 (S43), returns to step S6 of the first flow chart, and displays the display screen of the display 118 as desired. The confirmation screen 16 is switched to the transaction amount input screen 14 . If the reference time has not passed (S42: NO), the trading terminal 110 determines whether or not the selection operation of the buy button 16g has been received (S44), and has received the selection operation of the buy button 16g. If not (S44: NO), it is determined whether or not the selection operation of the stop button 16f has been accepted (S45). When the selection operation of the stop button 16f is received (S45: YES), the processing of the trading terminal 110 returns to the step of S6 in the first flowchart (in this case, the processing of the securities system 120 also follows, and the processing of the first flowchart return to processing).

Also, if the selection operation of the stop button 16f has not been received (S45: NO), the process returns to the stage of S41, and the trading terminal 110 continues timekeeping. If the selection operation of the buy button 16g is accepted (S44: YES), the trading terminal 110 displays the conditions displayed on the intention confirmation screen 16 (planned purchase amount, number of shares, purchase price, exchange rate for purchase). A transaction request execution is transmitted to the securities system 120 to the effect that a transaction request for the selected issue will be executed under the conditions indicated by the numerical values 7a to 7d indicated in the columns 16a to 16d.

The securities system 120 determines whether execution of a transaction request has been received from the logged-in trading terminal 110 (S52). If execution of a transaction request has not been received (S52: NO), the securities system 120 proceeds Next, it is determined whether or not a timeout notification has been received from the trading terminal 110 (S53). If a timeout notification has not been received (S53: NO), the process returns to the step of S52 to determine whether the execution of the transaction request has been received. I do. Also, if the time-out notification is received (S53: YES), the processing of the securities system 120 returns to the stage of S11 in the first flow chart, and various information is transmitted to the trading system 110. FIG.

Then, when the execution of the transaction request is received (S52: YES), the securities system 120 allows the logged-in user to trade the stock of the selected stock under the conditions (number of shares, purchase price, etc.) related to the execution of the transaction request. A purchase process (transaction process) is executed (S54), and when the transaction is completed, a transaction completion notice is transmitted to the trading terminal 110 (S55). The securities system 120 associates the contents of the completed transaction with the logged-in user and stores them in the user account table and the issue owned by the user 25 (S56). A series of processing related to the purchase is once terminated.

In addition, the trading terminal 110 determines whether or not it has received a transaction completion notification from the securities system 120 after transmitting a transaction request execution accompanying the selection operation of the buy button 16g (S47). ), if it has not been received (S47: NO), it will be in a state of waiting for reception, and if it has been received (S47: YES), the display screen of the display 118 will be switched from the intention confirmation screen 16 to the order establishment screen 17 (see FIG. 19). Processing is performed (S48). Due to the display of this order execution screen 17, the series of processing related to the current purchase of the selected issue on the side of the trading terminal 110 is once terminated.

As described above, in the stock trading method of the stock trading system using the trading terminal 110 and the securities system 120, the number of shares calculated based on the real-time market price at that time and various information are displayed on the display 118 of the trading terminal 110. Therefore, when the stock market opens, the user can check the trading conditions according to the fluctuating market price at any time, and there is an advantage that the fluctuating market price can be faithfully reflected in trading.

Although the first to third flow charts above have been explained in the case of buying the selected stock when the stock market opens, the processing flow for selling the stock of the stock owned by the user is basically the same as that for buying. become. The main difference is that in the first flowchart, step S4 determines whether or not selection of the sell button 13c has been accepted, and step S5 is transmission of a sale instruction. It becomes whether or not an instruction has been received, and furthermore, in the stage of S7, it becomes whether the selection of the sell button has been accepted in a state where the amount of money has been input and set, and in the stage of S8, a sale request is transmitted, and accordingly, the sales request is transmitted. , S12 also determines whether a sale request has been received. Then, in the third flow chart, the step of S44 determines whether or not the selection of the sell button has been accepted, and the transaction execution of S54 also carries out the processing of selling the stock of the selected issue.

Also, in the above description, real time means the most recent (latest) thing (value) at that time, but the real time of the present invention is limited to mean the most recent (latest) at that time. real-time, but also a range of seconds prior to that point in time (eg, a few seconds prior by the number of seconds, such as 3 seconds, 5 seconds, depending on the time interval at which the securities system 120 receives the market price). Therefore, for example, calculating the number of shares based on the market price 3 seconds or 5 seconds before the securities system 120 receives the purchase request at the stage of S12 of the first flow chart, or It corresponds to calculating the number of shares based on the market price, which will be in real time. This is the same when calculating the number of shares at the stage of S50 in the third flowchart. It corresponds to calculating the number of shares based on the real-time market price among the market prices calculated. In this way, by including the range several seconds before in real time, there is a margin for various processes related to stock number calculation and the like in the securities system 120 , which helps reduce the processing load of the securities system 120 .

Furthermore, the real-time value of the present invention also corresponds to the average value of a plurality of values included in the range from the latest (most recent) to several seconds ago, for example, the time (the time when a purchase request is received, or the time when a passcode is received, etc.) ) and the average value of multiple market prices, such as 3 seconds or 5 seconds before the latest, and use that average value as the real-time market price to calculate the number of shares. is also possible. By using the average price as the real-time market price in this way, the real-time value (market price) used to calculate the number of shares can be stabilized even when the market price fluctuates frequently or rapidly. benefits arise.

Also, the first to third flow charts described above have been explained as processing when the stock market is open, but basically the flow of processing is the same when the stock market is closed, and the main difference is the first The method of calculating the number of stocks at the stage of S13 of the flowchart and the stage of S50 of the third flowchart can be mentioned. In this case, when the securities system 120 receives a purchase request including the transaction amount when the stock market is closed, the trading amount is determined based on the market price of the selected issue at the time of closing stored in the stock price table 22. The number of shares of the selected stock is calculated. In addition to using the market issue at the time of closing, as in the real-time case described above, the stock prices stored in the stock price table 22 may be stored several seconds before (for example, 3 seconds, 5 seconds, etc.) before the closing time. It is also possible to calculate the number of shares based on the price (equivalent to the market price before the closing time), and furthermore, the market price at the closing time and the number of seconds before the closing time (for example, 3 seconds before, 5 seconds before etc.), and the number of shares may be calculated based on this average value. The same advantages as in the case (reduction of processing load, stabilization of values used for calculating the number of stocks) are obtained.

In addition, in the processing related to timeout in S23 and 24 of the second flowchart and S42 and S43 of the third flowchart, the display of the number of stocks, the market price, etc. placed on the screen is maintained as the reference time (fixed time). However, if you want to give the user more time to think, you should set the reference time to about 6 to 8 seconds or more (a fixed amount of time). time).

However, when using such a long number of seconds (approximately 6 to 8 seconds) as the reference time (fixed time), the securities system 120 receives new market prices for multiple issues from the stock exchange system 130 during that time. Therefore, in this case, in accordance with the newly received market price of each issue (including the selected issue) by the securities system 120, based on the newly received market price, the input set transaction amount In addition to calculating the number of shares of the selected issue when trading with , the newly calculated number of shares and various information are transmitted to the trading terminal 110 .

Each time the trading terminal 110 receives a new number of shares and various information, the number of shares or other numerical value displayed on the passcode input screen 15 or the intention confirmation screen 16 is changed to the numerical value included in the newly received number of shares or various information. , so that the latest (most recent) market price can be displayed on the screen, and the latest trading conditions (newly calculated number of shares, etc.) can be presented to the user even when longer trading hours are provided. do. Furthermore, it is also possible to make specifications that allow the user to make a trading decision with more time to spare. is omitted, the same processing is performed as in the case of using a longer number of seconds as the reference time. each time a new stock number is received, the trading terminal 110 switches to display the newly received stock number).

In addition, in the explanation of the first to third flowcharts described above, the market price is used as the transaction price (purchase price or sale price) as it is, so the business entity (securities company) that operates the securities system 120 separately A fee will be charged from the user, but in addition to that, as described above, it is also possible to execute transaction processing using the transaction price (purchase price or sale price) obtained by adjusting the spread to the market price. In this case, the number of shares will be calculated based on the above transaction price, but since the transaction price is the market price plus or minus the spread, even if the spread is adjusted to the price, the number of shares will still be the same as the transaction price. It will be calculated based on the underlying market price.

Specifically, when the stock market opens, any value within the range of about 0.2 to 0.5% of the market price is used as the spread. If the transaction is a purchase, the real-time market price at that time plus the above-described percentage spread is presented to the user as the purchase price (trading stock price). If the transaction is a sale, the real-time market price at that time minus the above-mentioned percentage spread is presented to the user as the selling price (trading stock price). The trading stock price (buying or selling price) with the spread added in this way is transmitted from the securities system 120 to the trading terminal 110, and the numerical value 4b on the transaction amount input screen 14 in FIG. 16 and the passcode input screen 15 in FIG. and the numerical value 7c of the purchase price column 16c of the intention confirmation screen 16 of FIG. If the spread is added or subtracted from the price, the number of shares will be calculated based on the market price with the spread added or subtracted.

In addition, when the stock market closes, the market price does not fluctuate, so it is preferable to secure a higher spread than when the market opens (for example, within the range of 0.6 to 0.8% of the market price). one of the included values). Furthermore, since the securities system 120 of the present invention processes stocks through negotiated transactions with stocks that have been acquired in advance and stocked, it may be difficult to adjust the number of stocks when the stock market is closed. In order to avoid stock stocks from becoming excessive or insufficient when the market is closed, the stock standard numbers for each stock are stored in the RAM 120c of the securities system 120 or in a large-capacity storage system. When the market is closed and the number of stocks of the selected issue to be traded falls below the inventory standard (the number of stocks is insufficient), if you wish to trade for user purchases, increase the spread to be added. , it is preferable to suppress the user's willingness to buy. For example, if the normal spread used when the market is closed is 0.7% when making a purchase when the market is closed, the spread will be changed to 0.9% or 1.0% when the number of stocks of the selected issue falls below the inventory standard. increase to

The above is the same when the stock market is closed and the number of stocks is excessive (when the number of stocks of the selected issue to be traded exceeds the stock standard) and the user wishes to sell. It is preferable to increase the spread so as to reduce the user's willingness to sell. In the case of this sale transaction, for example, if the normal spread at the time the market is closed is 0.7%, the spread will be reduced to 0.9% or 1.0% when the number of stocks of the selected issue exceeds the inventory standard. and increase.

Furthermore, in the above explanation, the stocks to be traded are those of overseas (US) companies, but of course, the present invention can be applied even when the stocks of companies in the home country (Japan) are traded. Yes, and if the issue of a company in the home country is to be traded, the processing related to exchange can be omitted in the above explanation.

Furthermore, in the above explanation, the stock trading application P2 is installed in the trading terminal 110 and various screens 11 to 17 are displayed. The securities system 120 is made to function as a web server, and on the website, the various screens 11 to 17, etc. described above can be displayed on the display 118 of the trading terminal 110 that is the access source. , and the above-described processing can be performed through various screens 11 to 17 on the website. In this way, it becomes unnecessary to install the stock trading application P2 on the trading terminal 110, and the present invention can be used only by accessing a website on a wide-area network such as the Internet. There are benefits that can be enhanced.

INDUSTRIAL APPLICABILITY When trading stocks online, the present invention can be suitably used for trading based on the number of stocks calculated based on real-time market prices when the stock market is open.
