Description

[Technical field]

[0001] The present invention relates to an information display system. [Background technology]

[0002] At stock exchanges and other places, information about the ever-changing buying and selling of securities is distributed via communication networks, and this information is displayed on a gigantic, circular, ribbon-shaped electronic bulletin board called a ticker board, where the text scrolls around in a flowing, rotating manner. The main information displayed on the ticker board is the name of the stock, the current stock price, and a comparison with the previous day's closing price.

[0003] Scrolling display not only conveys information such as stock prices to trading parties, but also conveys the overall market activity by changing the scrolling speed at which the information flows. For example, displaying information at a fast scrolling speed can convey a state where trading is active, while displaying information at a slow scrolling speed can convey a state where trading is sluggish or has ended. Usually, the scrolling speed can be changed in stages, and the number of stages can be appropriately determined according to the performance of the display device. The scrolling speed may also be changed continuously.

[0004] Figure 1 shows the overall concept of the network distribution and display system for securities information. Huge amounts of various types of trading information generated every moment at stock exchanges across the country are collected in the market report system in the form of securities information messages, and are then sent to the distribution service system.

[0005] In the distribution service system, these securities information messages (hereinafter referred to as "securities information" or simply "messages") are thinned out based on predetermined rules to reduce the amount of messages, and a message type code is assigned according to the message content before being distributed to the information display system 10 within the stock exchange.

[0006] Message types can be broadly divided into (1) control messages related to the timing of message delivery, (2) basic stock messages related to basic information about a stock such as stock code, stock name, and industry name, and (3) real stock messages related to market information such as order information, contract information, trading volume, and price information. Of these, real stock messages in type (3) are the target of scrolling display. However, order information is not included.

[0007] Furthermore, the above-mentioned real invoice messages include new messages that are sent when they occur during trading hours, backup messages that are sent after the end of the morning and afternoon sessions as closing data for each session, and day-to-day messages that are sent as day-to-day information after the end of trading on that day, and each of these is given a specific message type code.

[0008] The information display system 10 accumulates and updates the received messages, and tally them up every unit time to control the contents to be scrolled and the scroll speed. Finally, the information on the display contents and scroll speed thus determined is given to the information display device 15, which then scrolls them on a ticker board.

[0009] Regarding controlling the scrolling speed, for example, Patent Document 1 discloses controlling the scrolling speed based on the frequency of receiving messages (the number of real messages received for a stock per unit time) or the amount of information for stocks waiting to be displayed, or even a combination of these. [Prior art documents] [Patent documents]

[0010] [Patent Document 1] JP 2001-282227 A Summary of the Invention [Problem to be solved by the invention]

[0011] However, in Patent Document 1, the real message of a stock, which is the basis for calculating the scroll speed, also contains order information (hereinafter, also referred to as "quote"). Therefore, even if a trade is not executed, the scroll display speed may become faster if orders are concentrated on a specific stock, which causes the problem that the entire market is judged to be active.

[0012] Recently, there has been a trend to thin out and limit messages in distribution service systems as much as possible in order to reduce the burden on lines. For this reason, there is a demand for information display systems that can more accurately reflect the overall market activity, even if the amount of messages, which is the parameter for calculating the scrolling speed, decreases. [Means for solving the problem]

[0013] In order to solve the above problems, one representative information display system of the present invention provides an information display system that displays trading information in a market where buying and selling transactions take place, calculates the increase in trading volume per unit time, and changes the speed at which the trading information is scrolled in accordance with the increase. Effect of the Invention

[0014] According to the present invention, even if the amount of messages used as a parameter for calculating the scroll speed is generally reduced from the viewpoint of reducing the circuit load, by using the stock trading volume, which is directly linked to actual trading, for controlling the scroll display speed, it is possible to provide an information display system that more accurately reflects the overall market activity. Problems, configurations and effects other than those described above will become apparent from the description of the following embodiments. [Brief description of the drawings]

[Diagram 2] FIG. 2 is an overall conceptual diagram of an information display system 10 according to this embodiment. [Diagram 3]FIG. 3 is a diagram showing steps for calculating the scroll speed in this embodiment. [Figure 4] FIG. 4 is a conceptual diagram showing how a received message is stored and updated in the data storage area 12 and how the scrolling speed is calculated. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiment. In addition, in the description of the drawings, the same parts are denoted by the same reference numerals.

[0017] The trading information that is the subject of information display in this disclosure typically includes securities information such as stock prices, but is not limited to this, and also includes other securities information, financial information, and commercial transaction information as long as it is traded in the market and the price or trading volume changes from moment to moment.

[0018] In this disclosure, the information display unit on which information is displayed typically includes a ticker board, but is not limited to this and may include any display device that displays information in a scrolling manner, such as a received information display device consisting of a personal computer installed in the home.

[0019] 2 is an overall conceptual diagram of an information display system 10 according to this embodiment. The system includes a message reception processing unit 11 that receives securities information messages such as stock prices distributed via a wired or wireless communication line, a data storage area 12 secured in a memory for storing the received securities information, a data display processing unit 13 that sequentially reads out the received securities information stored in the data storage area 12 and processes it into predetermined display data, and a file data output storage unit 14 that stores the display data from the data display processing unit 13. An information display device 15 scrolls and displays the received securities information based on the display data stored in the file data output storage unit 14.

[0020] The information display system 10 also includes a scroll speed control processing unit 16, a scroll processing unit 17, a parameter setting processing unit 18, a parameter table 19, and an operation unit 20. The scroll speed control processing unit 16 determines the scroll speed based on message reception frequency information (the number of messages received within a unit time), the amount of securities information waiting to be displayed (the number of received messages waiting to be updated), or trading volume information detected by the message reception processing unit 11. The scroll processing unit 17 scrolls the display of securities information on the information display device 15 according to the determined scroll speed. The parameter setting processing unit 18 sets control conditions used in the scroll speed determination processing in the scroll speed control processing unit 16. Furthermore, the parameter table 19 holds the control conditions of the scroll speed determination processing, and the operation unit 20 accepts operation input from the user and holds the control conditions input to the parameter setting processing unit 18 in the parameter table 19.

[0021] That is, the scroll speed control processing unit 16 determines the scroll speed based on the message reception frequency information, the amount of securities information waiting to be displayed, or trading volume information, or further a combination of these, in accordance with the control conditions stored in the parameter table 19. Then, the scroll processing unit 17 causes the information display device 15 to scroll and display the received securities information at the determined scroll speed. The above-mentioned functional units 11, 13, 16 to 18 are configured by executing a predetermined processing program in a processor (CPU), but may be configured by a dedicated circuit. Also, the data storage area 12 and the parameter table 19 may be configured as separate areas in the same memory.

[0022] [Calculating scroll speed during trading hours] 3 is a diagram showing steps for calculating the scroll speed in this embodiment. The process flow will be described below for each step. <Step 1> In S1, when the previous unit time (hereinafter referred to as the "previous unit time") has passed and the current unit time (hereinafter referred to as the "current unit time") has begun, it is determined whether the current time is within the morning or afternoon trading hours, and if it is within the trading hours, the process proceeds to S2, and if it is outside the trading hours, the process proceeds to S5.

[0023] Thereafter, during trading hours, steps S2 to S4 calculate the scrolling speed S6 based on the increase or decrease in total trading volume, which is the gist of the present invention, and outside trading hours, step S5 calculates the scrolling speed S6 based on the number of receptions per unit time.

[0024] <Step 2> In S2, the value stored as the "current trading volume total" in the previous unit time is stored as the "previous trading volume total" in the current unit time. Here, the "current trading volume total" is the total trading volume of transactions included in messages received within the current unit time.

[0025] <Step 3> In S3, the "current trading volume total" which is the total value of the trading volume included in the received message in the current unit time is calculated.

[0026] <Step 4> In S4, the "current total trading volume" for the current unit time is compared with the "previous total trading volume" stored in S2 to calculate the increase in trading volume.

[0027] <Step 5> In S5, the number of receptions per unit time used for controlling the scroll speed outside trading hours is calculated.

[0028] <Step 6> In S6, the scroll speed control processing unit 16 calculates the scroll speed based on the increase in trading volume if it is within trading hours, and based on the number of receptions per unit time if it is outside trading hours, in accordance with the control conditions in the parameter table 19 or the operation unit 20 (operation input from the user).

[0029] Next, the calculation of the scroll speed within a trading time will be described in more detail with reference to Fig. 4. Fig. 4 is a conceptual diagram showing how a received message is stored and updated in the data storage area 12, and how the scroll speed is calculated.

[0030] The messages received by message receiving processor 11 from the distribution service system are sorted according to message type codes assigned according to the message contents, and are stored in a predetermined storage area of ​​data storage area 12 for each type.

[0031] For example, messages classified as basic issue messages are assigned to a storage area for issue information, and when a new issue emerges, a new storage area corresponding to that issue is secured and stored therein, while existing issues are updated appropriately in the storage area.

[0032] The messages classified as stock real messages are assigned to the stock price information storage area. In conjunction with the stock information storage area, stock price information is stored and updated in the stock price information storage area for each stock.

[0033] The real stock messages received and stored in the stock price information storage area also contain order information (quotes), but since no trades have been made, there are no trading volume figures. Therefore, when S3 calculates the total trading volume for the current unit time, order information is not counted, and only stocks for which trades have been made are counted, resulting in the total value being P.

[0034] 3, the "current trading volume total" M in the previous unit time is set as the "previous trading volume total" in the current unit time, and PM is obtained by taking the difference between P and M in S4. The scroll speed is calculated based on this "trading volume increase" PM in S6.

[0035] <Effects> In this way, during trading hours when active trading is expected, the trading volume of stocks that is directly linked to actual trading among the real stock message is used to control the speed of the scrolling display, making it possible to accurately reflect the overall market activity in changes to the scrolling speed.

[0036] [Calculating scroll speed outside trading hours] Next, referring again to Figure 3, calculation of the scroll speed during trading hours will be described in more detail. Since there are basically no transactions outside trading hours, if the calculation method used during trading hours is applied as is, the scroll speed will suddenly slow down, which would be unnatural. Therefore, as shown in Figure 3, if it is determined in S1 that the current time is outside trading hours, the process proceeds to S5, where a scroll speed different from that during trading hours is set.

[0037] Even outside trading hours, transient transactions such as transactions that cross over closing times, and even data at the time of closing, are received by the message receiving processing unit 11 as backup messages, so it is also possible to determine the scroll speed based on the number of messages received per unit time outside trading hours.

[0038] 3, a new scroll speed is determined based on the number of received messages acquired by the message reception processing unit 11 in the current unit time, in accordance with the conditions set in the scroll speed update method of the parameter table 19. In this case, the number of received messages includes order information (signs) that are not traded, but is not included in the number of received backup messages.

[0039] Furthermore, for example, in a case where the scrolling speed is set in several stages and the conditions for changing the stage are determined based on the number of received messages, the scrolling speed may be determined based on the conditions for changing the stage. On the other hand, if a correspondence table between the number of received messages and the scroll speed is set, a new scroll speed may be determined based on a value obtained from the correspondence table.

[0040] In this way, outside trading hours, the scroll speed is reduced, for example, step by step based on the number of messages received per unit time, and finally, information from the backup message can be displayed at the slowest speed.

[0041] <Effects> In this way, outside trading hours, the scrolling speed is gradually slowed down based on the number of messages received per unit time, making it possible to smoothly switch the scrolling display before and after trading hours.

[0042] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the gist of the present invention. For example, when determining the scrolling speed during trading hours, it is possible to determine the scrolling speed by taking into consideration not only the trading volume described above, but also information on the frequency of receiving messages and the amount of securities information waiting to be displayed.

[0043] Furthermore, for example, whether during trading hours or outside trading hours, the number of real stock messages received per unit time may be measured, and if the number of messages received per unit time is less than a set number, it may be determined that trading has ended, and the display speed may be slowed down by one level. This prevents the scroll speed from changing significantly immediately after the end of trading hours, and enables the scroll speed to be changed in a way that reflects the market situation during trading hours. However, it goes without saying that the end of trading should not be determined to be during actual trading hours.

[0044] It is also possible to control the scroll speed based on the amount of securities information waiting to be displayed. That is, a new scroll speed is determined according to the conditions set in the scroll speed update method of the parameter table 19, based on the amount of securities information waiting to be displayed acquired by the message receiving processor 11 in the current unit time.

[0045] In addition, the scroll speed can also be calculated during or outside trading hours based on an appropriate combination of information acquired by the message receiving processing unit 11, including trading volume information, message reception frequency information, and the amount of securities information waiting to be displayed.

[0046] For example, when controlling by effectively combining information on the frequency of message reception and the amount of securities information waiting to be displayed, it is possible to determine whether the current frequency of message reception acquired by the message reception processing unit 11 is equal to or above the minimum line set in the parameters of parameter table 19 when both are valid, and if it is equal to or above the minimum line, to acquire the corresponding scroll speed from the correspondence table set in the parameters when only the amount of securities information waiting to be displayed is valid, and if the frequency of message reception does not meet the minimum line, to determine a new scroll speed that is one step slower than the current speed.

[0047] Other suitable indicators than trading volume information may be used for scroll speed control as long as they reflect the overall market activity during trading hours. For example, it is possible to control the scroll speed based on the trading value calculated by multiplying the trading volume by the stock price. [Explanation of symbols]
