Description

  The present invention relates to a stock price chart display system, a stock price chart display method, and a stock price chart display program, and more specifically, a stock price data display system, a stock price data display method, and a stock price chart display that display a stock price chart based on stock price data on a display screen. Regarding the program.

  Investors participating in stock trading typically use stock price charts to determine stock trading. Recently, a stock price chart can be easily browsed by connecting a computer to the Internet and accessing a server storing a plurality of stock price data.

  Referring to FIG. 28, the stock price chart has a stock price axis on the vertical axis and a time axis on the horizontal axis. The stock price chart is, for example, a candlestick chart 200 or a moving average line 201, and shows the transition of the stock price during a predetermined period (for example, 3 months in FIG. 28).

  An investor can visually determine the transition of the stock price using the stock price chart. In FIG. 28, since the stock price has risen sharply, the investor can determine that the stock price has risen visually. Furthermore, since the stock price on the latest day is about 1960 yen and the stock price on the first day of the period (3 months before the latest day) is about 1830 yen, the fluctuation range of the stock for the past three months is about 130 yen. It can be easily understood that the earnings per share is about 130 yen. As described above, the stock price chart is effective investment information that can easily visually grasp the transition and fluctuation range of the stock price of the stock.

  However, it is not possible to grasp at a glance a stock with a high rate of return (yield) simply by looking at the stock price chart.

  For example, when comparing the stock price chart of Bank A shown in FIG. 28 with the stock price chart of Bank B shown in FIG. 29, all stock prices show the same transition (upward).

  Here, the rate of return of bank A and bank B can be calculated by the following equation (1).

Rate of return (%) = (stock price on the latest day-stock price on the first day of the period) / stock price on the first day of the period x 100 (1)
The latest stock price for Bank A is about 1960 yen, and the stock price for the first day of the period is about 1830 yen, so the return on Bank A shares is about 7%. On the other hand, since the stock price of the latest bank B stock is about 175 yen and the stock price on the first day of the period is about 150 yen, the profit rate of the bank B stock is about 17%. Therefore, the trend of the stock price on the stock price chart looks the same between Bank A and Bank B, but the rate of return is higher for Bank B stock than for Bank A stock.

  As described above, it is difficult to grasp the rate of return of the stock price simply by looking at the stock price chart. In addition, as shown in FIG. 30, when a plurality of stock price charts are displayed in the same size on the display screen even though the stock price levels of each stock are different, a stock with a high return rate and a stock with a low return rate are displayed. It is difficult to grasp at a glance.

Japanese Patent Application Laid-Open No. 2005-31838 (Patent Document 1), Japanese Patent Application Laid-Open Publication No. 2004-227070 (Patent Document 2), and Japanese Patent Application Laid-Open No. 2002-92329 are disclosed. However, even if these systems are used, it is difficult to grasp at a glance a brand with a high profit rate from a stock price chart.

The client may include a receiving unit, an acquiring unit, a selecting unit, a calculating unit, a chart creating unit, an object creating unit, and a display unit.

  The stock price chart display system according to the present invention displays the fluctuation range drawing object together with the stock price chart. The fluctuation range drawing object indicates a fluctuation range extending in the stock price axis direction. Since the fluctuation range indicates the predetermined fluctuation rate range of the stock, if the fluctuation of the stock price chart is large relative to the fluctuation range drawing object, it can be judged at a glance that the return rate (variation rate) of the stock is high. If the fluctuation of the stock price chart is small with respect to the width drawing object, it can be determined at a glance that the return of the stock is low. Therefore, by displaying the stock price chart together with the fluctuation range drawing object, it is possible to visually grasp the fluctuation rate of the stock, and to judge at a glance a brand with a high profit rate.

  Preferably, the display unit displays the fluctuation range drawing object so as to overlap the stock price chart.

  In this case, since the fluctuation range drawing object and the stock price chart are displayed in an overlapping manner, the fluctuation of the stock with respect to the fluctuation range object can be grasped more visually.

  Preferably, the display means displays the fluctuation range drawing object at a reference stock price position on the stock price chart.

  In this case, since the fluctuation range drawing object is displayed at the reference stock price position, it is possible to grasp the fluctuation of the stock near the reference stock price with respect to the fluctuation range drawing object.

  Preferably, the stock price chart has a time axis intersecting with the stock price axis, and the object creation means has a width corresponding to a fluctuation width in the stock price axis direction and a fluctuation width having a length corresponding to a predetermined time in the time axis direction. Create a drawing object.

  In this case, the fluctuation range drawing object has a band-like shape that is typically extended in the time axis direction of the stock price chart. Therefore, the fluctuation of the stock price chart with respect to the fluctuation range drawing object can be grasped more visually.

  Preferably, the brand information includes a reference stock price selection condition, and the selection unit selects the reference stock price based on the reference stock price selection condition.

  In this case, the reference stock price can be freely selected according to the reference stock price selection condition. Therefore, the fluctuation range drawing object can be created based on the desired reference stock price.

  Preferably, the brand information includes information on a plurality of different brands, the acquisition means acquires stock price data of the plurality of brands based on the brand information, and the display means has a stock chart of the same size as each brand price. Display them side by side.

  In this case, since a plurality of stock price charts are displayed side by side, it is easy to compare stocks of respective brands. At this time, since the plurality of stock price charts have the same size, it is possible to visually compare the overall stock price transitions for all stock price charts. Furthermore, since each stock price chart is displayed together with the fluctuation range drawing object, it is possible to visually grasp the stock fluctuation rate as well as the stock trend.

  Preferably, the storage means includes an industry database and a stock price database. In the industry database, a plurality of industry IDs and a plurality of brand IDs associated with the plurality of industry IDs are registered. In the stock price database, a plurality of stock price data associated with a plurality of brand IDs are registered. The brand information includes a business type ID, and the acquisition unit acquires a brand ID corresponding to the business type ID included in the brand information from the business type database, and acquires stock price data of the acquired brand ID from the stock price database.

  In this case, if the business category ID is included in the brand information, the stock price charts of a plurality of brands in the industry can be displayed side by side.

  Preferably, the stock price chart display system includes a server and a client connectable to the server. The server includes storage means, and the client includes reception means, acquisition means, selection means, calculation means, chart creation means, object creation means, and display means.

  In this case, the client creates a stock price chart or creates a fluctuation range drawing object. Therefore, the load on the server is reduced.

  A stock price chart display method according to the present invention is a stock price chart display method using a server having storage means for storing stock price data of a plurality of brands and a client connectable to the server, and transmits brand information from the client to the server. A step of acquiring stock price data of a desired brand from the storage means based on the brand information, a step of selecting a reference stock price from the acquired stock price data, a reference stock price and a predetermined rate of change.

  In the stock price chart display method according to the present invention, the fluctuation range drawing object is displayed together with the stock price chart. The fluctuation range drawing object indicates a fluctuation range extending in the stock price axis direction. Since the fluctuation range indicates the predetermined fluctuation rate range of the stock, if the fluctuation of the stock price chart is large relative to the fluctuation range drawing object, it can be judged at a glance that the return rate (variation rate) of the stock is high. If the fluctuation of the stock price chart is small with respect to the width drawing object, it can be determined at a glance that the return of the stock is low. Therefore, by displaying the stock price chart together with the fluctuation range drawing object, it is possible to visually grasp the fluctuation rate of the stock, and to judge at a glance a brand with a high profit rate.

  A stock price chart display program according to the present invention is a program that is executed by a client that can be connected to a server that stores stock price data, the step of obtaining stock price data of a desired brand from the server, and from among the obtained stock price data, Selecting a reference stock price; calculating a fluctuation range based on the reference stock price and a predetermined rate of change; creating a stock price chart having a stock price axis based on the stock price data; The client is caused to execute a step of creating a fluctuation range drawing object indicating the extended fluctuation range and a step of displaying a stock price chart together with the fluctuation range drawing object.

  If the stock price chart display program according to the present invention is installed in the client, the fluctuation range drawing object can be displayed together with the stock price chart. The fluctuation range drawing object indicates a fluctuation range extending in the stock price axis direction. Since the fluctuation range indicates the predetermined fluctuation rate range of the stock, if the fluctuation of the stock price chart is large relative to the fluctuation range drawing object, it can be judged at a glance that the return rate (variation rate) of the stock is high. If the fluctuation of the stock price chart is small with respect to the width drawing object, it can be determined at a glance that the return of the stock is low. Therefore, by displaying the stock price chart together with the fluctuation range drawing object, it is possible to visually grasp the fluctuation rate of the stock, and to judge at a glance a brand with a high profit rate.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated.

1. First Embodiment First, the configuration of a stock price data display system according to the present embodiment will be described.

1-1. Configuration Referring to FIG. 1, stock price data display system 1 includes a server 10 and a plurality of clients 20. The server 10 is connected to a plurality of clients 20 via a network 2 such as the Internet.

  The server 10 includes a CPU (Central Processing Unit) 11, a memory 12, a communication unit 13, and a hard disk 14, which are connected to each other via a bus 15. The communication unit 13 is connected to the network 2 and transmits / receives data to / from the client 20.

  The hard disk 14 stores a stock price database 141 and an industry database 142. As shown in FIG. 2, the stock price database 141 includes a security code as a stock ID and a plurality of stock price data associated with each stock ID.

  The stock price database 141 has a plurality of stock price records of the brand specified by the securities code. The stock price record is a field in which a date is registered, a field in which an opening price is registered, a field in which a high price is registered, a field in which a low price is registered, a field in which a closing price is registered, and a volume. Field. In the stock price record, daily stock price data is registered in time series.

  The industry database 142 has a plurality of industry records shown in FIG. Each industry record has a field for registering an industry code and a field for registering a securities code. The business type code is identification information (business type ID) of each business type. For example, “0001” is the banking industry, and “0026” is the movie industry. The securities code is registered in association with the industry code.

  The hard disk 14 of the server 10 further stores a stock price chart creation program. A stock price chart creating program is loaded into the memory 12 and the CPU 11 executes the stock price chart creating program, whereby a stock price chart creating process to be described later is executed.

  The client 20 includes a CPU 21, a memory 22, a display 23 that displays a stock price chart, a hard disk 24, a keyboard 26 and a mouse 27 that function as an input unit, and these are connected to each other via a bus 29. A browser for accessing the server 10 and browsing web pages is installed in the hard disk 24.

1-2. Operation Next, the operation of the stock price data display system 1 will be described.

1-2-1. Outline of Operation A user (investor or the like) of this service uses the client 20 to request a stock price chart of a desired brand from the server 10. The server 10 creates a stock price chart in response to the request. The server 10 further calculates a virtual fluctuation range based on a reference stock price (for example, the closing price on the latest day) in the stock price chart and a predetermined fluctuation rate, and as shown in FIG. 4, a fluctuation having the calculated fluctuation range B0. A width drawing object (hereinafter referred to as a variable width object) 50 is combined with a stock price chart. Hereinafter, the stock price chart to which the fluctuation range object is assigned is referred to as a fluctuation range chart.

  The fluctuation range object 50 includes an upper fluctuation width portion 51 above the reference stock price SP0 and a lower fluctuation width portion 52 below the reference stock price SP0. The length of the fluctuation range object 50 in the stock price axis direction is a length B0 in which the calculated fluctuation width is matched to the scale of the stock price axis.

  The user can determine the change rate (return rate) of the stock at a glance by referring to the chart with the change width and comparing the change width object 50 and the transition of the stock price. Details of the operation will be described below.

1-2. When Displaying Stock Price Charts for One Brand Referring to FIG. 5, first, the client 20 accesses the server 10 (S1). The server 10 transmits the input screen shown in FIG. 6 in response to the access of the client 20 (S2). The client 20 displays the transmitted input screen on the display 23.

  The input screen includes an input box 101 for inputting a security code, input boxes 102 and 103 for inputting a rate of change (%), and a period selection area 104 for selecting a period on the time axis of the stock price chart. including. The fluctuation rate is composed of an upward fluctuation rate for setting the upper limit of the fluctuation range and a lower fluctuation rate for setting the lower limit of the fluctuation range. The input box 102 is an input box for upward fluctuation rate, and the input box 103 is an input box for downward fluctuation rate. In the period selection area 104, check boxes are provided for each period (3 months, 6 months).

  The user of the client 20 uses the keyboard 26 and the mouse 27 to input a desired securities code into the input box 101 (for example, the securities code 1031 of A bank). Further, when setting the variation rate, the user further inputs a desired upward variation rate (for example, + 3%) into the input box 102 and inputs a desired downward variation rate (for example, −3%) into the input box 103. Furthermore, when selecting a period, a check box in the period selection area 104 is selected. The securities code is required to be entered, but the rate of change and selection of the period are optional.

銘柄情報はユーザにより入力された証券コードを含む。また、ユーザが変動率（上方変動率及び下方変動率）や期間を入力した場合、これらの情報も含む。なお、銘柄情報は、基準株価を設定するための基準株価選択条件を含む場合もある。基準株価選択条件については後述する。 After the input, the user selects the transmission button 105 with the mouse 27. When the transmission button 105 is selected, the client 20 transmits the brand information shown in Table 1 to the server 10 (S3).

The brand information includes a security code input by the user. Moreover, when a user inputs a fluctuation rate (upward fluctuation rate and downward fluctuation rate) and a period, such information is also included. The brand information may include a reference stock price selection condition for setting a reference stock price. The reference stock price selection condition will be described later.

  The server 10 receives the brand information transmitted from the client 20 (S4). The received brand information is stored in the memory 12. The server 10 selects stock price data corresponding to the securities code (1031) included in the stock information from the stock price database 141, and acquires stock price data within a predetermined period from the selected stock price data (S5). . When the brand information includes period information, the server 10 acquires stock price data for a period (for example, the past three months from the latest date) based on the period information. If the brand information does not include period information, stock price data for a preset period is acquired. The preset period information is stored in the hard disk 14.

  The server 10 registers the acquired stock price data together with the securities code in the acquisition database 143 shown in FIG. Referring to FIG. 7, acquisition number, securities code, and acquired stock price data are registered in acquisition database 143. As will be described later, when acquiring stock price data of a plurality of issues, acquisition numbers are assigned in the order of acquisition. Since only the stock price data for one brand (Bank A) is acquired this time, the acquisition number is “1”. The acquisition database 143 is stored in the memory 12.

  After acquiring the stock price data, the server 10 creates a chart with fluctuation range based on the stock price data registered in the acquisition database 143 (S100: stock price chart creation processing).

  First, the acquisition number n = 1 is set (S6), and the stock price data of the acquisition number 1 is read from the acquisition database 143 (S7). Subsequently, a reference stock price is selected from the read stock price data (S8: reference stock price selection process), a fluctuation range is calculated based on the selected reference stock price (S9: fluctuation range calculation process), and a chart with a fluctuation range is created. (S10: chart creation process with fluctuation range). Details will be described below.

[Standard Stock Price Selection Process (S8)]
Referring to FIG. 8, server 10 determines whether the brand information received in step S4 includes a reference stock price selection condition (S81). As shown in Table 1, since the brand information does not include the reference stock price selection condition (NO in S81), the server 10 selects the latest price closing price from the stock price data as the reference stock price (S82). In step S82, “the closing price of the latest day” is set as the reference stock price selection condition. This selection condition is registered in advance in the hard disk 14 of the server 10. The selection conditions can be changed.

[Variation range calculation process (S9)]
Referring to FIG. 9, server 10 determines whether or not the brand information received in step S4 includes a change rate (upper change rate and lower change rate) (S91). When the brand information does not include the change rate (NO in S91), the server 10 sets the change rate to a predetermined change rate (S92). The predetermined fluctuation rate is registered in the hard disk 14 in advance.

  On the other hand, as shown in Table 1, when the brand information includes the fluctuation rate (YES in S91), the fluctuation rate is the fluctuation rate included in the brand information (upward fluctuation rate = + 3%, downward fluctuation rate = −3%). (S93).

  After setting the fluctuation rate, the server 10 uses the reference stock price (the latest price closing price) selected in step S8 and the set fluctuation rate (upward fluctuation rate + 3%, downward fluctuation rate -3%) to The fluctuation range is calculated based on Equation (2) (S94).

Fluctuation width = Up fluctuation range + Down fluctuation range = Base stock price x (Upward fluctuation rate-Downward fluctuation rate) (2)
When the reference stock price is 1960 yen, the virtual fluctuation range is 118 yen according to Equation (2). The upper fluctuation range and the lower fluctuation range are 59 yen each.

[Chart creation process with fluctuation range]
After setting the reference stock price and the fluctuation range, a chart creation process with a fluctuation range is executed (S10). With reference to FIGS. 10 and 11, first, the server 10 creates a stock price chart based on the stock price data registered in the acquisition database 143 (S101). At this time, the chart database 144 shown in FIG. 12 is generated and stored in the memory 12 (S102). The chart database includes coordinate data of stock price data (open price, low price, high price, close price) of each date constituting the chart. The chart database 144 further includes coordinate data of a time axis (x axis) and a stock price axis (y axis). Specifically, the x coordinates x _min and x _max at both ends of the time axis in FIG. 11 are included. In addition, the y coordinate y _max of the maximum value (stock price _max ) of the stock price axis and the y coordinate y _{min of the} minimum value (stock price _min ) are included.

Subsequently, the server 10 refers to the chart database 144 and specifies the y coordinate of the reference stock price SP0 (S103). In this embodiment, since the reference stock price is the closing price of the latest date, y coordinate = y ₀ corresponding to the closing price of the latest date (April 15, 2005) in the coordinate database is set as the y coordinate of the reference stock price SP0. Identify.

Subsequently, the y coordinate of the fluctuation range upper limit B1 and the fluctuation range lower limit B2 constituting the fluctuation range is specified (S104). In step S <b> 9, the fluctuation range is already calculated and stored in the memory 12. Server 10, the following equation (3) and (4), calculates the y-coordinate = _{y 1} of fluctuation range upper limit B1, and a y-coordinate = _{y 2} fluctuation range limit B2.

以上の計算により、変動幅上限Ｂ１の座標ｙ_１と、変動幅下限Ｂ２の座標ｙ_２とが特定される。

By the above calculation, the coordinate y ₁ of the fluctuation range upper limit B1, and the coordinate y ₂ of the variation width limit B2 are identified.

描画範囲を設定後、変動幅オブジェクト５０を作成する（Ｓ１０６）。具体的には、上述の描画範囲の座標に基づいて、上変動幅部分５１と下変動幅部分５２とを作成し、上下変動幅部分５１及び５２を所定の色に設定する。このとき、上変動幅部分５１と下変動幅部分５２の色が異なるように設定する。 Subsequently, the drawing range of the variable width object is set (S105). As shown in FIG. 4, when the fluctuation range object 50 is displayed over the entire range of the time axis of the stock price chart, and the upper fluctuation range portion 51 and the lower fluctuation range portion 52 are distinguished and displayed with different colors or the like. The range surrounded by the coordinates shown in Table 2 below using the y coordinates = y0 to y2 obtained in steps S103 and S104 and the x coordinates of both ends of the time axis = x _min , x _max The drawing range is set (S105).

After setting the drawing range, the variable width object 50 is created (S106). Specifically, the upper fluctuation width portion 51 and the lower fluctuation width portion 52 are created based on the coordinates of the drawing range described above, and the upper and lower fluctuation width portions 51 and 52 are set to a predetermined color. At this time, the upper variation width portion 51 and the lower variation width portion 52 are set to have different colors.

  After creating the fluctuation range object 50, the fluctuation range object 50 is combined with the stock price chart (S107). At this time, the candlestick chart and the moving average line in the stock price chart are synthesized so as to overlap the fluctuation range object 50.

  With the above processing, the chart with fluctuation range shown in FIG. 4 is created. The data of the created chart with fluctuation range (hereinafter referred to as chart data with fluctuation range) is temporarily stored in the memory 12.

  Returning to FIG. 5 again, after creating the fluctuation range chart, the server 10 increments the acquisition number n to n = 2 (S11), and whether or not the stock price data of the acquisition number 2 is registered in the acquisition database 143. (S12). In the present embodiment, since only stock price data of one brand is acquired, it is determined that the stock price data of acquisition number 2 is not registered in the acquisition database 143 (NO in S12), and the created chart with fluctuation range is It is determined that there is one (YES in S13).

  Therefore, the server 10 transmits the chart data with the fluctuation range stored in the memory 12 to the client 20 (S15).

  The client 20 receives data from the server 10 (S16), and displays the chart with fluctuation range shown in FIG. 4 on the display 23 (S17).

With the above operation, the user of the client 20 can view the chart with the fluctuation range of the desired brand (A bank). Referring to FIG. 4, since the fluctuation of the candlestick chart and the moving average line is small with respect to the fluctuation width B0 of the fluctuation width object 50, the user sees that the rate of return (variation ratio) of the stock is low. I can judge. On the other hand, in the chart with fluctuation range of Bank B shown in FIG. 13, since the fluctuation of the candlestick chart and the moving average line is larger than the fluctuation range B0, the user has a high rate of return (variation rate) of the stock. It can be judged at a glance.
Further, in the charts with fluctuation ranges shown in FIGS. 4 and 13, since the fluctuation range object 50 is displayed so as to overlap the stock price chart, it is easy to visually grasp the fluctuation of the stock price with respect to the fluctuation range object. Further, the variable width object 50 is displayed so that the central portion of the width is arranged at the position of the reference stock price. Therefore, it is possible to judge at a glance the fluctuation of the stock in the vicinity of the reference stock price.

表３に示す銘柄情報は、表１に示す銘柄情報に加えて、基準株価選択条件として日付情報（２００５年３月１日）を含む。日付情報は、ユーザがキーボード２６を用いてクライアント２０に入力される。また、図１４に示すように、ユーザがマウス２７を操作して、株価チャート上の時間軸が「２００５年３月１日」となる位置にマウスポインタ２８を移動させ、日付を指定することにより、日付情報がクライアント２０に入力されてもよい。 1-2-3. When changing the reference stock price of the displayed chart with fluctuation range The user who has viewed the chart with fluctuation range displayed on the display 23 may want to change the reference stock price SP0 and redraw the fluctuation range object 50. is there. In FIG. 4, when the user wants to set the closing price on March 1, 2005 as the new reference stock price SP0, the client 20 transmits the brand information shown in Table 3 to the server 10 based on the user operation (S3). .

The brand information shown in Table 3 includes date information (March 1, 2005) as a standard stock price selection condition in addition to the brand information shown in Table 1. The date information is input to the client 20 by the user using the keyboard 26. Further, as shown in FIG. 14, the user operates the mouse 27 to move the mouse pointer 28 to a position where the time axis on the stock price chart is “March 1, 2005” and designate the date. Date information may be input to the client 20.

  The server 10 receives the brand information in Table 3 (S4), and executes a standard stock price selection process (S8). Referring to FIG. 8, server 10 determines that the received brand information includes the standard stock price selection condition (YES in S81), and the standard stock price selection condition is date information (YES in S83). Therefore, the server 10 selects the closing price on the date of the date information (March 1, 2005) as the reference stock price from the stock price data (S84).

  Based on the selected reference stock price, the operations after step S9 are executed. As a result, in the chart with fluctuation range displayed in step S17, as shown in FIG. 15, the closing price on March 1, 2005 is the reference stock price SP0, and the reference stock price SP0 is located at the center of the fluctuation range B0. A width object 50 is displayed.

  In the above description, the user designates a desired date and selects the reference stock price. However, the user may directly select the reference stock price. When the user wants to set a desired stock price as the reference stock price, the brand information includes the stock price as the reference stock price setting condition. The stock price may be input to the client 20 by the user using the keyboard 26, or the position where the stock price axis becomes a desired stock price on the chart with fluctuation range displayed on the display 23 may be designated with the mouse 27. . In this case, in the standard stock price selection process in step S8 (see FIG. 8), the server 10 determines that the received stock information includes the standard stock price selection condition (YES in S81), and the standard stock price selection condition is not date information. Judgment is made (NO in S83). Therefore, the server 10 selects the stock price included in the brand information as the reference stock price (S85). The subsequent operation is as described above.

  As described above, the user can freely change the reference stock price SP0. Therefore, the variable width object 50 can be freely changed according to the user's preference.

Note that the shape of the variable width object 50 can be freely set. For example, as shown in FIG. 16, the object shape may be a vertically long object shape, or as shown in FIG. 17, the object shape in which “△” marks are added to portions corresponding to the fluctuation range upper limit B1 and the fluctuation range lower limit B2. But you can. In this case, since the apex of each “Δ” mark indicates the position of the fluctuation range upper limit B1 and the lower limit B2, the distance between the “Δ” marks indicates the fluctuation range B0.
Furthermore, the arrangement position of the variable width object 50 can be arbitrarily changed. For example, as shown in FIG. 18, the fluctuation range object 50 may be displayed by matching the stock price _max (y _max ) of the stock price axis with the upper limit of the fluctuation range object 50. Further, as shown in FIG. 18, it is not necessary to distinguish the upper variation width portion and the lower variation width portion. In any object shape, the length B0 in the stock price axis direction of the fluctuation range object 50 is a length obtained by matching the fluctuation range calculated in step S9 with the scale of the stock price axis.
In the present embodiment, the upward fluctuation rate and the downward fluctuation rate are set to the same value (3%), but may be different from each other.

1-2-4. When displaying a stock price chart of a plurality of brands Normally, a user who is an investor compares stock price charts of a plurality of different brands and determines which brand of stock to buy or sell. Therefore, it is preferable that the display 23 can list a plurality of charts with fluctuation ranges side by side. Furthermore, it is preferable to be able to list charts with fluctuation ranges of a plurality of issues in the same industry. Hereinafter, a case where the user lists a chart with fluctuation ranges of a plurality of brands will be described.

  Referring to FIG. 5, when the client 20 accesses the server 10 (S1), the server 10 transmits the industry type input screen shown in FIG. 19 (S2). The industry input screen includes an industry selection area 106 having a plurality of check boxes for selecting an industry, input boxes 102 and 103 for change rates, and a period selection area 104. The user of the client 20 selects a desired business type (for example, a bank), inputs a change rate and a period as necessary, and then selects the transmission button 105 by operating the mouse 27.

サーバ１０は、銘柄情報を受信後（Ｓ４）、図３に示す業種データベース１４２を参照して、銘柄情報内の業種コード（銀行：０００１）に対応して登録された証券コードを全て選択する。続いて、選択した複数の証券コードに対応した複数の株価データを、株価データベース１４１から検索し、最新日から所定期間分（たとえば３ヶ月分）の株価データを取得する。要するに、同じ業種コードに分類された複数の銘柄の株価データを全て取得する。取得した複数の株価データは、銘柄ごとに図２０に示すように、取得データベース１４３に登録される。 When the transmission button 105 is selected, the client 20 transmits the brand information including the industry code to the server 10 as shown in Table 4 (S3).

After receiving the brand information (S4), the server 10 refers to the industry database 142 shown in FIG. 3 and selects all securities codes registered corresponding to the industry code (bank: 0001) in the brand information. Subsequently, a plurality of stock price data corresponding to the selected plurality of securities codes is searched from the stock price database 141, and stock price data for a predetermined period (for example, three months) from the latest date is acquired. In short, all the stock price data of a plurality of brands classified into the same industry code are acquired. The acquired plurality of stock price data is registered in the acquisition database 143 for each brand as shown in FIG.

  After acquiring the stock price data, the stock price chart creation process of step S100 is executed for each stock price data of each brand. Specifically, first, the acquisition number n = 1 is set (S6), and the stock price data of the acquisition number 1 is read from the acquisition table (S7). Subsequently, a reference stock price selection process (S8), a fluctuation range calculation process (S9), and a chart creation process with a fluctuation range (S10) are executed. The chart with fluctuation range of the chart with fluctuation range created in S10 is registered in the chart registration database 145 shown in FIG. 21 together with the securities code. The chart registration database 145 is stored in the memory 12.

  After executing the operation of step S10, the acquisition number n is incremented to n = 2 (S11), and it is determined whether or not the stock price data of the acquisition number 2 is registered in the acquisition database 143 (S12). As a result of the determination, stock price data of acquisition number 2 is registered (YES in S12), so the process returns to step S7 again to create a chart with fluctuation range of the issue of acquisition number 2 (S8 to S10).

After creating a chart with fluctuation ranges for stock price data (for example, 12 in FIG. 20) registered for the acquisition database 143 (NO in S12), the server 10 refers to the chart registration database 145 shown in FIG. Then, it is determined that a plurality of chart data with fluctuation ranges are registered (NO in S13). Therefore, the server 10 creates a layout of the display screen so that a plurality of charts with fluctuation ranges are displayed in a list on the display screen of the display 23 (S14: layout creation processing).
Referring to FIG. 22, the server 10 acquires arrangement area information stored in advance in the hard disk 14 (S141). When displaying a list of a plurality of charts with variation widths, as shown in FIG. 23, the arrangement area of the charts with variation widths of the respective chart numbers in the display screen is determined in advance. Information regarding this arrangement area is arrangement area information. Furthermore, since it is necessary to create a chart with a fluctuation range for each arrangement area size shown in FIG. 23, the chart with a fluctuation range created in step S10 must be reduced. Therefore, the server 10 acquires reduction rate information for reducing the chart with fluctuation range to the size of the arrangement area (S141). The reduction rate information is stored in the hard disk 14 in advance.

  The server 10 recalculates the chart data of each chart number registered in the chart registration database 145 using the acquired arrangement area information and reduction rate information (S142). The server 10 registers the recalculated chart data as reduced chart data in the list database 146 shown in FIG. 24 (S143). A securities code corresponding to the reduced chart data is also registered. The list database 146 is stored in the memory 12. After registration, the server 10 ends the layout editing process.

  Returning to FIG. 5, the server 10 transmits to the client 20 all the reduced chart data registered in the list database 146 and the securities codes corresponding to each reduced chart data (S15). The client 20 receives the reduced chart data and the securities code (S16) and stores them in the memory 22. Further, a list of a plurality of charts with fluctuation ranges is displayed on the display 23 using the reduced chart data as shown in FIG.

  Referring to FIG. 25, a plurality of charts with fluctuation ranges are displayed side by side with the same size. Therefore, the user can easily grasp the fluctuation rate (revenue rate) of each brand after comparing the fluctuation range objects 50 of the brands. For example, when comparing chart A with fluctuation range 60 of bank A and chart 70 with fluctuation range of bank B in FIG. 25, the transition of the stock of bank A is the same as the transition of the stock of bank B at a glance. appear. However, since the width of the fluctuation range object 50A of the A bank is wide, it can be determined that the A bank stock has not greatly changed with respect to the fluctuation range object 50A, and the user can determine that the fluctuation rate of the A bank stock is low. On the other hand, since the width of the fluctuation range object 50B of the B bank is narrow, it can be determined that the B bank stock has largely fluctuated with respect to the fluctuation range object 50B, and the fluctuation rate of the B bank stock can be determined to be high.

  Therefore, the user can judge at a glance that the bank B has a higher profit rate than the bank A.

  When the user wants to display only the chart with the fluctuation range of A bank on the display screen among the plurality of charts with the fluctuation range of FIG. 25, the user designates the chart 60 with the fluctuation range of A bank with the mouse 27 or the like. The client 20 reads the stock code of the chart with fluctuation range 60 designated by the mouse 27 or the like from the memory 22, and requests the server 10 for chart data with a fluctuation range corresponding to the read stock code. Upon receiving the request, the server 10 acquires chart data with a fluctuation range corresponding to the received securities code from the chart registration database 145 and transmits it to the client 20. The client 20 receives the chart data with the fluctuation range and displays the chart with the fluctuation range for only the bank A as shown in FIG.

  With the above operation, the client 20 can display only a desired chart with a fluctuation range on the display 23 from among the plurality of charts with a fluctuation range in FIG.

  As shown in FIG. 26, in addition to a plurality of charts with fluctuation ranges, a chart 80 with a fluctuation range of the Nikkei Stock Average may be displayed as a reference issue.

2. Second Embodiment In the first embodiment, the server 10 executes the stock price chart creation process in step S100. However, for the purpose of distributing the load of the server 10, the client 20 executes the stock price chart creation process. Also good.

  In this case, the stock price chart creation program is installed on the hard disk 24 in the client 20. The stock price chart creation program is, for example, an applet downloaded to a browser. As will be described later, the stock price chart creation program may be downloaded from the server 10 or may be installed in the client 20 in advance.

  When the stock price chart creation program is loaded into the memory 22 and the CPU 21 executes the stock price chart creation program, the client 20 creates a chart with a fluctuation range. Details will be described below.

  Referring to FIG. 27, when client 20 accesses server 10 (S1), server 10 transmits a stock price chart creation applet together with an input screen (S21).

  The client 20 receives the input screen and the stock price chart creation applet, and installs the stock price chart creation applet (S22). As a result, the stock price chart creation program is started on the browser. Further, the server 10 displays an input screen on the display 23.

  Subsequently, the client 20 transmits the brand information input based on the user operation to the server 10 (S3). Note that the brand information here includes the securities code or the industry code, but does not include the fluctuation rate input on the input screen. The input variation rate is stored in the memory 22.

  The server 10 receives the brand information (S4), acquires stock price data of a desired brand from the stock price database 141 based on the securities code or the industry code in the brand information, and transmits it to the client 20 (S23).

  The client 20 receives the stock price data, and acquires the stock price data by registering it in the acquisition database 143 stored in the hard disk 24 (S24). Subsequently, the acquisition number n = 1 is set (S6), and a stock price chart creation process is executed (S100). After executing the stock price chart creation process, the chart with fluctuation range is displayed on the display 23 (S17).

  With the above operation, the stock price chart creation process can be executed by the client 20 instead of the server 10. Thereby, load distribution of the server 10 becomes possible.
