Abstract

PROBLEM TO BE SOLVED: To realize a credit dealing on a stock exchange support system and a virtual stock exchange game system. SOLUTION: When a virtual selling order of stock is received from a terminal 16, the selling order is judged on whether it is related to a short selling order or not according to the number of stock holdings in a stock exchange server 12. And if it is judged to be related to the short selling, the system deals with the selling order as an order partly or wholly containing the short selling, while if it is judged to be not related to the short selling, the system deals with the selling order as a regular selling order.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stock trading support system and a virtual stock trading game, and more particularly to a technology for enabling margin trading in a stock trading support system and a virtual stock trading game.

[0002]

2. Description of the Related Art A network stock trading support system has become widespread in which stock trading can be easily carried out from a personal computer or a mobile phone via the Internet or a mobile phone network. Also, with the spread of such systems, virtual stock trading game systems that allow users to enjoy virtual stock trading from personal computers and mobile phones via the Internet and mobile phone networks have gained popularity.

[0003]

Among stock transactions, margin trading is a special transaction mode in which an investor borrows funds or stocks from a securities company, and there are empty selling and empty buying (margin trading in a narrow sense). . Kara sell is to borrow a stock certificate from a securities company and sell it, and also repurchase and return the same name to a securities company within a predetermined period to earn the difference between the sale price and the purchase price (capital gain). Aim. On the other hand, the purpose of buying empty money is to purchase stock certificates by borrowing funds from a securities company, and also to sell the stock certificates within a predetermined period, and to earn the difference (capital gain) between the purchase price and the sale price. According to such margin trading, investors can trade more than the original one. In addition, especially in the case of empty selling, investors will buy stock certificates of stocks that have collapsed in price, which is also useful for relief of such stocks.

However, such a meaningful margin transaction is not supported by the conventional stock trading support system or the virtual stock trading game system. If the stock trading support system can support margin trading, it can be expected that stock trading (net trading) using such a system will be further activated. In addition, if the virtual stock trading game system can support credit trading, stock trading can be performed by users or more, so that the fun of the game can be increased. Further, even if the stock price is expected to fall, it is possible to increase profits by stock trading, so that the player can enjoy the stock trading game at any time.

[0005] The present invention has been made in view of the above problems, and has as its object to provide a stock trading support system capable of performing margin trading and a virtual stock trading game system capable of performing virtual margin trading.

[0006]

In order to solve the above-mentioned problems, a stock trading support system according to the present invention comprises: an order receiving means for receiving a stock selling order from a user; Determination means for determining whether or not, if the sell order is determined to be related to the empty sell order, the sell order is processed as an order that includes the empty sell order in part or all, On the other hand, when it is determined that the sell order is not related to the empty sell order, order processing means for processing the sell order as a normal sell order is included.

The stock trading support method according to the present invention further comprises an order receiving step of receiving a stock selling order from a user, a determining step of determining whether or not the selling order is related to an empty selling order. If it is determined that the sell order is related to an empty sell order, the sell order is processed as an order that partially or completely includes the empty sell order, while the sell order is related to an empty sell order. If not, an order processing step of processing the sell order as a normal sell order.

According to the present invention, when it is determined that a sell order is related to an empty sell order, it is processed not as a normal sell order but as an order partially or wholly including the empty sell order. Will be done. For this reason,
In the stock trading support system, empty selling (credit trading) becomes possible, and net trading can be further activated.

In one aspect of the present invention, the determining means includes means for allowing a user to specify whether or not the sell order is related to a empty sell order, and based on the user's designation, It is determined whether or not the sell order is related to the empty sell order.

It is determined whether it is related to or not. In this way, for example, when there is a selling order for a brand not owned by the user, it can be determined that the selling order is a blank selling order, and the order acceptance can be simplified.

In one aspect of the present invention, the apparatus further includes storage means for storing the name of the stock held by the user and the number of the stock, wherein the order receiving means receives a sell order for the stock specifying the stock and the number of stocks. The determination means checks how many shares the user who is the main of the sell order holds the brand specified by the sell order based on the storage content of the storage means, and determines the number of shares held and the sell price. It is determined whether or not the sell order is related to the empty sell order based on the number of shares specified by the order. In this case, for example, when the user who is the orderer does not have the designated stock (ordered stock) only for the designated stock (ordered stock), the selling order can be determined to be related to the empty selling order. It is possible to simplify the acceptance of orders.

In one aspect of the present invention, the order processing means converts the sell order into a normal sell order and an empty sell order based on the checked number of shares and the number of shares specified by the sell order. Including means for reconfiguring. In this way, for example, when a sell order exceeding the number of shares held is accepted, a normal sell order is performed up to the number of shares held, and a sell order is reconfigured as an empty sell order for the amount exceeding the number of shares held. Is possible, and acceptance of orders can be simplified.

The virtual stock trading game system according to the present invention also includes an order receiving means for receiving a virtual stock sell order from a player, and determines whether the sell order is related to an empty sell order. Determining means for processing the sell order as an order including a part or all of the empty sell order when the sell order is determined to be related to the empty sell order; Order processing means for processing the sell order as a normal sell order when it is determined that the sell order is not related to the order.

[0014] In the control method of the virtual stock trading game system according to the present invention, there is provided an order receiving step of receiving a virtual stock sell order from a player, and determining whether or not the sell order is related to an empty sell order. And if the sell order is determined to be related to the empty sell order, the sell order is processed as an order that includes some or all empty sell orders, while the sell order is If it is determined that the selling order is not related to the empty selling order, an order processing step of processing the selling order as a normal selling order is included.

According to the present invention, if it is determined that the sell order is related to the empty sell order, it is processed not as a normal sell order but as an order partially or wholly including the empty sell order. Will be done. For this reason,
In the virtual stock trading game system, it is possible to perform a blank sale (a credit transaction), and it is possible to increase the fun of the game.

The stock trading support system according to the present invention further comprises: an order receiving means for receiving a stock trading order from a user; a determining means for determining whether the stock trading order is related to margin trading; If it is determined that the stock trading order is related to margin trading, the stock trading order is processed as an order including some or all of the margin trading orders, while the stock trading order is related to margin trading. If not, an order processing means for processing the stock trading order as related to a normal stock trading;

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a diagram showing an overall configuration of a virtual stock trading game system according to an embodiment of the present invention. Here, an example will be described in which the system shown in FIG. 1 is used as a virtual stock trading game system for producing virtual stock trading by a player, but a stock trading support for supporting a real stock trading by a user. It can also be used as a system. The only difference between the two is that the transaction mainly instructed from the terminal 16 and the stock market data and the contract data supplied to the stock transaction server 12 are virtual or real. Here, a virtual stock trading game system will be described, but a stock trading support system for supporting real stock trading by replacing "player" with "user" and "virtual" with "real" is also described. It can be easily implemented by the following description.

The virtual stock trading game system 10 shown in FIG.
Provides a virtual stock trading game for virtually trading stocks in a game space to a plurality of players, and includes a stock trading server 12 and a plurality of terminals 16. The stock transaction server 12 and the terminal 16 are communicatively connected via the Internet 14 so as to be able to exchange data.
A virtual stock trading game is provided to the terminal 16 by the perText Transfer Protocol. That is, the stock trading server 12 executes C for realizing the virtual stock trading game.
A well-known server computer that executes a GI (Common Gateway Interface) program. A URL (Uniform Resource Locator) is transmitted as a game command from a terminal 16 composed of various data processing devices such as a personal computer, a home game machine, and a mobile phone. Receive,
It returns a hypertext representing the game screen. The stock exchange server 12 is provided with stock market data from a stock exchange or a securities company via, for example, a dedicated line. The stock market data includes data representing a contract price, a quote price, a trading volume, etc. of each stock issue. Further, contract data specifying contracted ones of the trading orders received by the stock transaction server 12 is also supplied. When the stock trading server determines a virtual contract for each order in the game space,
Contract data is generated internally. When the system shown in the figure is configured as a stock trading support system, the contract data may be supplied from the outside via a communication line, or may be manually input by a keyboard or the like.

FIG. 2 shows this virtual stock trading game system 1.
FIG. 7 is a diagram showing an example of a main menu screen displayed on the terminal 16 at 0. The main menu screen shown in the figure is displayed on a display provided in the terminal 16 based on a hypertext transmitted as a response when a URL for starting the virtual stock trading game is transmitted to the Internet 14. It is. As shown in the figure,
On this main menu screen, three link buttons of “stock name information”, “asset”, and “stock trade” are prepared, and when a player selects and operates any one of them, a URL corresponding thereto is displayed on the stock trade server 12. Is sent again. The “stock issue information” is a menu for the player to designate a stock issue and refer to the stock price or the like of the issue. “Assets” is a menu for the player to refer to his or her own assets. Also, "Stock Trading"
Is a menu for the player to designate a stock brand and to place an order to buy and sell the specified number of shares of the stock.

FIG. 3 shows the main menu screen.
When "Stock Information" and "Stock Trading" are selected,
An example of a brand search screen displayed next on the terminal 16 is shown. The stock search screen shown in the figure is for referencing stock prices and specifying stock stocks to be traded. The player inputs a numerical value on the terminal 16 and presses a “start” button (link button). Then, a list of brands whose numerical values are included in the brand code is returned to the terminal 16. When a character is input, a list of brands whose characters are included in the formal or informal name of the company is displayed on the terminal 16.
Is to be replied to. When the player selects one of the stock brands in the brand list (not shown), the stock brand information shown in FIG. That is, the figure shows an example of a stock brand information screen displayed on the display of the terminal 16 in response to a brand selection by the player. On this stock issue information screen, for example, the issue name, issue code, current value and time,
The trading volume and its time are displayed.

Further, even if the player selects "stock trading" on the main menu screen, a brand search screen shown in FIG. 3 is displayed on the terminal 16, and when the player inputs a search key on the screen, a brand list is displayed. Is then displayed on the terminal 16. Then, when the player selects one of the stock issues in the issue list, an order screen for the designated issue is displayed. FIG. 5 shows an example of this order screen. As shown in the figure, on this stock trading screen, the name of the stock, the stock code specified by the player, the current value of the specified stock are displayed, a form for inputting the number of shares to be purchased or sold, and a limit order The form for inputting the limit price in is displayed. Further, a “buy” button (link button) and a “sale” button (link button) are displayed side by side below the lower part.

The player inputs the number of shares to be purchased or sold in the upper form on the same screen, inputs the limit price in the lower form, and presses the "purchase" button below in the case of purchase. In the case of sale, the "sale" button below is pressed. If the "buy" button or the "sell" button is pressed while the form for the limit price is left blank, it is determined that the order is a successful order. In addition, a radio button for selecting whether the sale is a limit order or a subsequent order may be prepared on the stock trading screen shown in FIG. In the case of purchase, the stock transaction server 12 refers to the asset database shown in FIG. 7 and transmits a warning message as necessary so that the player can purchase within the range of cash virtually possessed in the game space. .

The virtual stock trading game system 10
Is specifically configured to allow margin trading.

That is, the order screen shown in FIG. 5 is provided with a check box (credit transaction check box) for instructing a margin transaction, and clicks the margin transaction check box with a mouse or the like to put a check. Then, all the orders on the same screen will be handled as related to margin trading. More specifically, if the user presses the “purchase” button after checking the margin transaction check box, the terminal 16 transmits an empty purchase order for the brand and the number of shares specified on the screen to the stock transaction server 12. If the user clicks the “Sell” button after checking the margin transaction check box, the terminal 16 transmits an empty selling order for the brand and the number of shares specified on the screen to the stock transaction server 12.

It should be noted that the margin transaction check box shown in the figure is displayed only on the credit screen, that is, only on the transaction screen for the issue for which margin transaction is permitted. Specifically, the stock transaction server 12 holds a flag indicating whether or not the brand of the code is a credit brand in association with the brand code, and displays a credit transaction check box on the same screen based on the flag. It is determined whether or not to display.

Also, in reality, empty selling or empty buying requires a commission deposit of an amount obtained by multiplying the selling price or the purchase price by a prescribed commission deposit rate (for example, 30%). In this virtual stock trading game system 10, a designated amount from cash virtually held by the player in the game space is used as a security deposit in a virtual (in a stock trading support system that supports actual stock trading, ) Can be deposited into a margin trading account. The stock trading server 12 can refer to the balance of the credit trading account of each player, and when receiving the empty selling order or the empty buying order from the terminal 16, the balance of the credit trading account of the player who is the orderer is calculated. Then, the amount is compared with an amount obtained by multiplying the selling price or the purchase price by the consignment margin rate, and it is determined whether or not the empty selling order or the empty buying order can be accepted. When it is determined that the reception is not possible, the fact is returned to the terminal 16, and when it is determined that the reception is acceptable, the empty selling order or the empty buying order is accepted.

It is to be noted that not only the designated amount from the cash held by the player is used for the commission deposit, but also the stock designated by the player and the number of the shares (substitute securities) among the shares held as a part or all of the commission deposit. Is also good. At this time,
It is realistic that the valuation value of the substitute security is obtained by multiplying the market value by a predetermined valuation rate, that is, a so-called security margin (for example, 70% for stocks). The market price may be obtained from stock market data supplied to the stock trading server 12.

In the case of a game, the concept of the security deposit may be simplified in particular, and for example, some or all of the cash and stock held by the player may be handled as the security deposit without any special instructions. In this case, when the empty selling order or the empty buying order is received from the terminal 16, the stock transaction server 12 determines whether or not the order can be accepted based on the valuation value of the cash or stock held by the player who is the orderer. to decide. This eliminates the need for the player to manage the credit transaction account, thereby simplifying the game.

In addition, if the stock purchased in the empty purchase order suddenly drops in price, or if the stock sold in the empty sell order suddenly increases in price, the loss cannot be filled by the commission deposit alone. In this case, an additional compensation, a so-called additional proof, may be requested from the player.

Further, the virtual stock trading game system 1
At 0, the player can designate the handling of the excess order on the option setting screen shown in FIG. In other words, on the same screen, select the radio button to the left of "Transfer excess orders to margin trading" and press the "Set" button, if a sell order is placed,
If the number of shares held by the player of the brand related to the order is less than the number of shares ordered (specified number of shares), the excess amount, that is, the amount obtained by subtracting the number of shares held from the number of ordered shares, is used as the empty selling order, and all of the number of shares held is the normal Assume a sell order. If a purchase order is placed and the purchase price (the market price of the order brand (specified brand) multiplied by the number of shares ordered) exceeds the cash held by the player, the excess amount and the money For unsatisfiable stocks, a blank buy order is used, and the rest are normal buy orders. On the other hand, on the same screen, if the radio button to the left of “If there is an excess order, the order is not accepted” and then the “Set” button are pressed, when a sell order is placed, the player of the brand related to the order will be If the number of shares held is lower than the number of shares ordered, the stock trading server 1
From 2 to the terminal 16, an order screen as shown in FIG. 5 is retransmitted together with a message such as “the number of shares ordered exceeds the number of shares held”. Also, if a purchase order is made and the purchase price exceeds the cash possessed by the player, the stock transaction server 12 sends a message to the terminal 16 such as "insufficient money". And an order screen as shown in FIG. Note that the setting contents on the option setting screen are recorded in the stock transaction server 12 in association with each player.

FIG. 7 shows the recorded contents of an asset database for recording stock assets and cash assets virtually owned by each player in the game space. This asset database is built in a storage device (not shown) such as a hard disk storage device of the stock transaction server 12, and includes an ID for identifying a player, a brand virtually owned by the player, and each brand owned by the player. The number of shares held by each issue is recorded in association with each other. In the asset database, an ID for identifying a player, an amount of cash virtually held by the player, and an e-mail address of the player are recorded in association with each other. The e-mail address is used for notifying a player who has margin traded an e-mail of a repurchase date for empty selling or a resale date for empty buying. Note that I
D is to be included as an argument of all URLs transmitted from the terminal 16 to the stock trading server 12 during the game, and the URL received by the stock trading server 12 relates to a game command from any player. So that it can be determined with certainty.

FIG. 8 shows the recorded contents of the margin transaction database for recording the result of the margin transaction virtually performed by each player in the game space. This credit transaction database is also built in a storage device (not shown) of the stock transaction server 12, and has an ID for identifying a player.
And the name of the stock that has been margin traded (empty or sold), the number of shares, the settlement date (sell back date for empty buy, repurchase date for empty sell), and the empty sell flag ( (1 is set for empty selling, and 0 is set for empty buying.)
And are stored in association with each other.

If there is a margin transaction, the stock transaction server 12 registers the margin transaction in the margin transaction database. At this time, a date when a predetermined number of months has elapsed from the transaction date is recorded in the “due date” column. Then, the stock transaction server 12 sends an e-mail to the e-mail address recorded in the asset database when the "due date" column approaches. This way,
The player can know the settlement date by e-mail.

The operation of the virtual stock trading game system 10 having such a configuration will be described below.

FIG. 9 is a flowchart illustrating the operation of the virtual stock trading game system 10. As shown in FIG. 1, in the virtual stock trading game system 10, the stock trading server 1
2 receives the order from the terminal 16 (S101), FIG.
In the order screen shown in (1), it is checked whether or not the check button on the left side of "Perform margin trading" is checked. If the check is checked, all of the ordered shares are processed as margin trading (S109). Specifically, in the credit transaction database shown in FIG. 8, the ID of the player who is the orderer, the code of the brand specified by the order (order brand), the number of trading stocks specified by the order (number of stocks ordered), the settlement date (For example, 6 months from the transaction date), and the empty selling flag are registered.

On the other hand, when the check button to the left of “Perform margin trading” is not checked on the order screen shown in FIG. 5, the order brand of the player who is the orderer is held from the asset database shown in FIG. Read the number of shares (for a sell order) or money (for a buy order) (S1
03). Next, it is checked whether the designated number of shares (ordered number of shares) exceeds the number of shares held in the case of a sell order, or whether the purchase price exceeds the money in possession in the case of a buy order (S104). If “N (No)” in S104, the order is a sell order within the range of the number of shares held or a buy order within the range of the money held, so the number of shares ordered for the order brand (different from margin trading) is usually (S105). Specifically, in the case of a sell order, in the asset database shown in FIG. 7, the numerical value in the number of shares column stored in association with the ID of the player who is the orderer and the brand code of the same brand as the ordered brand is represented by And the selling price is added to the value in the cash column. In the case of a buy order, in the asset database shown in FIG. 7, the number in the number of shares column stored in association with the ID of the player who is the orderer and the brand code of the same brand as the ordered brand is increased by the number of ordered shares. , Subtract the purchase price from the value in the cash column. If the player does not yet have the order brand, a record is added to the asset database so that the brand is newly added to the holding brand.

On the other hand, if "Y (Yes)" in S104, it is checked whether the radio button on the left side of "Transfer excess order to margin trading" is selected on the option setting screen (S106). If the radio button is not selected, it is determined that the radio button to the left of “No order is accepted if there is an excess order” is selected, and an error message indicating that the order is not accepted is sent to terminal 16. It transmits (S108). On the other hand, if the radio button on the left side of “Transfer excess order to margin transaction” is selected on the option setting screen, the order is reconfigured to margin transaction and normal transaction (S107). Specifically, in the case of a sell order, the sell order is reconfigured into a normal sell order for selling all the shares held and an empty sell order for the number of shares obtained by subtracting the number of shares held from the ordered stock for the order brand. The specific processing for the normal sell order and the empty sell order is as described above. Also, in the case of a buy order, the buy order is reconfigured so that the number of shares that can be purchased with the money held is a normal buy order and the remaining number of shares is an empty buy order.

According to the above, margin trading can be realized in the virtual stock trading game system.
Even if the stock price of many stocks is expected to fall, profits can be obtained through virtual stock trading, and the fun of the game can be increased. Also,
Part of the order can be automatically transferred to margin trading according to the relationship between the number of designated shares and the number of shares held, or the relationship between the purchase price and the money in possession, thus simplifying the order and improving convenience. Can be.

Note that the present invention is not limited to the embodiment described above.

For example, in the above description, the system shown in FIG. 1 is applied to a game in which a player enjoys virtual stock trading with the terminal 16, but the system is configured such that the user performs real stock trading with the terminal 16. Is also good. In this case, FIG.
Is constructed as a stock trading support system. At this time, if you want to automatically transfer part or all of the order to margin trading according to the relationship between the number of designated shares and the number of shares held, or the relationship between the purchase price and the money you have,
It is desirable to notify the user that part or all of the order is about to be transferred to margin trading so that stock trading can be performed with confidence.

In the above description, on the option setting screen shown in FIG. 6, as options for handling the excess order, "transfer the excess order to margin trading" and "do not accept the order if there is an excess order" are prepared. However, it is also possible to prepare "ignore excess portion if there is an excess order" so that even if there is an excess order, it is regarded as an order within the range of the number of shares held or the money held. Furthermore, when there is a trading order for the number of shares that is overwhelmingly larger than the number of shares held (for example, when the number of shares
Alternatively, if the number of shares ordered is equal to or greater than the number of shares held plus a predetermined number), all of the ordered shares may be determined to be related to margin trading.

[0045]

As described above, according to the present invention,
Margin trading can be performed in a stock trading support system or a virtual stock trading game system. In particular, in the virtual stock trading game system, the profit can be increased by the virtual stock trading at any time regardless of the market situation, so that the fun of the game can be increased.
