Description

  The present invention relates to a stock price chart display system and a stock price chart display program using a graphical user interface.

In general, stock charts are widely used in stock trading transactions. In the conventional stock chart, the stock price is set on the vertical axis and the time (time, day, week, month) is set on the horizontal axis. This shows the transition (see, for example, Non-Patent Document 1).
E-trade Securities website <URL: https://newtrading.etrade.ne.jp/ETGate/>

  However, in the above-mentioned conventional stock price chart, information such as trading price is not reflected in the stock price chart until the stock is bought and sold, so traders, fund managers and investors can quickly obtain sufficient information on stock trading from the stock price chart. It was difficult to obtain reliably.

  In general, traders and fund managers trade stocks while monitoring the operation of algorithms in spreadsheets and matrix spreadsheets using a trading management system (EMS) or order management system (OMS). However, in conventional EMS and OMS, in order to monitor the past operation of the algorithm, such as the contents executed by the algorithm one hour ago, it is necessary to dig up the spreadsheet, which is very time consuming. was there.

  The present invention has been made to solve the above-mentioned problems, and a stock price chart display by a graphical user interface that allows a trader, fund manager, and investor to obtain sufficient information about stock trading quickly and reliably. An object of the present invention is to provide a system and a stock price chart display program.

  In order to achieve the above object, the present invention provides a stock price chart display system using a graphical user interface, a stock price chart display means for displaying a stock price chart represented by a stock price axis and a time axis, A first graphic display means for displaying an order that has been established on the stock price chart by a first graphic, and an order that has not been traded on the stock chart by a second graphic having a shape different from the first graphic. And a second graphic display means for displaying.

  Then, the first graphic display means determines the position of the first graphic according to the stock trading time and the trading price, determines the size of the first graphic according to the amount of stock trading completed, The color of the first graphic is determined according to the format, and the second graphic display means determines the position along the price axis of the second graphic according to the order price of the stock. The length of the second graphic along the time axis is determined according to the time that is valid without being canceled, and the color of the second graphic is determined according to the stock order form. It is preferable to determine the transparency of the second figure by the amount.

  The present invention is also a stock price chart display program using a graphical user interface, the step of displaying a stock price chart expressed by a stock price axis and a time axis, and an order in which stock trading is completed is represented by a first graphic. A step of displaying on the stock price chart, and a step of displaying on the stock price chart a second figure having a shape different from that of the first figure. .

  The position of the first graphic is determined according to the trading time and trading price of the stock, the size of the first graphic is determined according to the amount of stock trading, and the color of the first graphic is the stock trading format. The position along the price axis of the second graphic is determined by the order price of the stock, and the length along the time axis of the second graphic is unsettled from the stock order acceptance time Preferably, the color of the second graphic is determined by the stock ordering format, and the transparency of the second graphic is determined by the stock order quantity.

  According to the present invention, a trader and an investor can obtain sufficient information about buying and selling stocks quickly and reliably through a graphical user interface.

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

  FIG. 1 shows a transaction flow of an entire system including an algorithm 10 of a stock price chart display system according to an embodiment of the present invention. This overall system is a securities company that performs stock trading at a public exchange or asset management. Used by the company.

  Usually, access to the algorithm 10 of this stock price chart display system is made from the trading management system (EMS) 11 or the order management system (OMS) 12. The trader can access the stock chart display system algorithm 10 from EMS 11 or OMS 12 provided by a third party software vendor. OMS 12 has been used by asset managers for many years to track and maintain information about stock portfolios, trading orders, etc., and a “back end” to store and maintain basic data for stock trading. (E.g., a database) and a "front end" (i.e., user interface) for entering and displaying order-format data.

  The algorithm 10 of the stock price chart display system according to the embodiment of the present invention includes a stock price chart display means for displaying a stock price chart represented by a stock price axis and a time axis on the display of the EMS 11 or the OMS 12; A first graphic display means for displaying an order for which trading has been completed on the stock price chart with a first graphic (in the present embodiment, a circle), and a shape different from the first graphic for orders for which trading has not been completed Second graphic display means for displaying on the stock price chart by a second graphic (rectangular in the present embodiment). The stock price chart display system algorithm 10 executes a series of commands in accordance with the stock price chart display program according to the embodiment of the present invention installed in a computer connected to the exchange 14, thereby managing the trading management system ( The stock price chart is displayed on the EMS) 11 or the order management system (OMS) 12 in real time by a graphical user interface.

  The first graphic display means determines the position of the first graphic based on the trading time and trading price of the stock, determines the size of the first graphic according to the amount of stock trading, and determines the stock trading format. The color of the first graphic is determined, and the second graphic display means determines the position along the price axis of the second graphic according to the order price of the stock, and trading is not yet established from the stock order reception time The length along the time axis of the second graphic is determined according to the time that is effectively present without being canceled, the color of the second graphic is determined according to the stock order form, and the order quantity of the stock The transparency of the second graphic is determined.

  The OMS 12 or EMS 11 may use a network message protocol called Financial Information Trading (FIX) protocol 13 to connect the asset management company to the securities company and send orders to the securities company's stock chart display system algorithm 10. It has become. Also, in this case, the asset management company can place an order with a securities company's sales trader by telephone or e-mail, or use a system provided by a securities company known as direct market access (DMA) 14 to exchange it. You can also deal directly with 15.

  As shown in FIG. 2, an order sent to the algorithm 10 of the stock price chart display system is called a “parent order”. Once the parent order is accepted by the stock chart display system algorithm 10, it is divided into smaller sized orders called “child orders” and then sent to major exchanges for sale. The general relationship between a parent order and a child order is “one-to-many”.

  The algorithm 10 of the stock price chart display system independently determines the amount of each child order sent to the exchange 15, the time of each child order, the total number of child orders, and the form of each child order. Child orders sent to the exchange are either bought and sold immediately or added to an order reservation queue waiting to be bought and sold at the ordered price. These orders are bought or sold after a certain time or canceled after a predetermined time by the algorithm 10 of the stock price chart display system.

  FIG. 3 shows an example of a stock price chart. This stock price chart represents the best bid price and the best bid price two-dimensionally. The vertical axis of this stock price chart represents the range of prices at which stocks can be obtained in the market, the horizontal axis represents time, the internal chart area is the seller side area (upper half), the bid price and sell price spread area, It consists of three areas, the buyer side area (lower half). Here, the best ask price is the boundary between the seller side and the spread of the bid price and the ask price, and indicates the lowest price at which the seller of the stock agrees to sell the stock. The best bid price is the boundary between the buyer side and the spread between the bid price and the ask price, and indicates the highest price that the stock buyer agrees to buy.

  The algorithm 10 of the stock price chart display system displays the sales order of the child order in a circle on the stock price chart. Child order buying and selling has four important characteristics: price, time, quantity, and type, all of which are represented by different characteristics of a circle. That is, as shown in FIG. 4, the vertical position along the circular price axis indicates the trading price, the horizontal position along the circular time axis indicates the trading time, and the circular area (or size) indicates the trading volume. The color of the circle indicates the trading format. Trading formats include buying and selling at the best bid price, buying and selling at the best bid price, buying and selling by auction, and buying and selling outside the market.

  As shown in FIG. 5, in the present embodiment, trading at the best bid price is colored in the same color (green) as the seller side, and trading at the best bid price is the same color (red) as the buyer side. It is colored with. Auction trades are trades that occur at the start or end of the trading time (for example, Toshiro), and are colored with a color (yellow) different from the buy / sell at the best bid price or the buy / sell price at the best bid price. Has been. Furthermore, off-market trading is represented by a circle colored in a different color (white) than all other trading formats. Off-market trades can fall within the bid and sell bid spreads, and these trades are shown in white in FIG.

  In FIG. 5, one yellow circle represents one auction transaction at a value of 3,110 yen, one red circle represents one sale made by a buyer in the market at a value of 3,120 yen, The four green circles represent the four trades made by the seller in the market with a value of 3,110 yen, and the three white circles are the market with values of 3,115 yen, 3,115 yen and 3,118 yen Shows three trades outside.

  As shown in FIG. 6, child orders that have not been traded are displayed as rectangles, which have four important characteristics: price, start and end time, quantity, and type.

  When the rectangle is on the seller side, the rectangle represents the selling child order. In the case of a selling child order, the lower side of the rectangle is the selling price, and in the case of child order A in FIG. 6, the selling price is 3,490 yen. Further, when the rectangle is on the buyer side, the rectangle represents a child order for buying. In the case of a child order for buying, the upper side of the child order is the buying price. In the case of child order C in FIG. Represents a child order.

  The length along the rectangular time axis represents the duration of the child order, which is the time that the child order remains valid in the market without being canceled or fully sold. is there. In the example of FIG. 6, the child order period is 15 minutes.

  The color of the rectangle represents the child order format. Child order formats vary by stock market exchange, and there are several order formats such as open market, closed market, limit orders, market orders supported by most exchanges around the world.

  As shown in FIGS. 6-8, the rectangular color is shown in yellow for open or closed markets and orange for open market or closed market limits. . Also, limit orders during consecutive witnesses are indicated in either blue or pink color depending on whether the order is being bought or sold. And the market order during the consecutive session where at least a portion was bought and sold is shown in blue.

The transparency of the rectangle represents the stock order quantity. For the stock chart display system algorithm 10 to determine the transparency of the rectangle, the following two measures are used. That is,
(1) Child orders that occupy a large percentage of the original parent order quantity are represented in lighter (or more uniform) colors.
(2) Child orders that occupy a large percentage of the normal stock volume of the public exchange are represented in a lighter (or more uniform) color.

  For example, in FIG. 6, it can be seen that the order quantity of the child order A is larger than the child order B because the pink color of the child order A is brighter than the pink color of the child order B.

  In the above-described embodiment, the first graphic is circular, the second graphic is rectangular, and the first graphic and the second graphic are colored with different specific colors, but these are merely examples. Needless to say, various changes can be made to the shape and color of the figure.
