Description

Embodiments described herein relate generally to image display in conjunction with mouse operation of a computer system.

In recent financial and securities systems, a securities ordering system, which is a computer system, is common and used under heavy traffic. The securities ordering system incorporates a board screen and displays board information and ordering (ordering) information. On the board screen, the current price of the displayed brand is displayed in the center, and when the price fluctuates, the display range is scrolled so that the current price becomes the display center.

In the securities ordering system, it is important to quickly order a large amount of data and place an order safely. Since the ordering work is performed by clicking the board screen, if the number of times the board screen is scrolled increases, there is a risk of erroneous ordering due to an operation error.

Under such circumstances, the operation of the new system of the stock exchange, where the update of the board information has become significantly faster, has been started, but from the user (dealer) who used the board screen, Many people are concerned about misordering.

To solve this problem, in the image display technology linked with the mouse operation, when an image to be scrolled in the display area is selected with a pointer such as a finger, the image is proportional to the distance between the image on the display area and the pointer. Then, the scrolling speed of the image is reduced, and the scrolling of the image is stopped when the position of the image matches the position of the pointer. That is, the scroll is decelerated and stopped by the mouse pointer position information.

However, such a method is suitable for an operation of selecting an image to be scrolled in the display area, but is not suitable for a system in which the display area itself is scrolled.

On the board ordering screen in the conventional securities ordering system, the order quantity is displayed as a numerical value. Therefore, if frequent updates are performed, it is difficult to quickly read numerical values and judge market conditions.

The update frequency of the board screen accompanying the increase in the amount of information in recent years exceeds the range that humans can process visually, and an unrecognizable amount of information does not make sense as information. In addition, there is a concern about erroneous ordering due to an operation mistake in clicking a place different from the intended place by scrolling the screen.

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

FIG. 1 is a block diagram of a securities ordering system according to an embodiment.

The securities ordering system is a computer system in which an ordering client 11 having a board screen 10 and a board data distribution server 12 are connected to each other.

In the client 11, a board data reception process 13 is operating on the processor. When the board data receiving process 13 is notified of the request for the brand information to be displayed by TCP / IP, the board data receiving process 13 sends a distribution request to the board data distribution server 12, and the board data received from the board data distribution server 12 is sent to the shared memory 14. Write.

In the client 11, a GUI program for displaying the board screen 10 is executed by the processor, and the board screen display process 13 is operating.

The board screen display process 15 accesses the shared memory 14 at regular intervals, and draws the obtained board data on the board screen 10. The board data can be arbitrarily switched to a display method using numerical data or a display method using a graph.

The board screen display process 15 controls screen updating and scrolling. The current price of the displayed brand is displayed at the center of the board screen 10, and when the price fluctuates, the display range is scrolled so that the price after the fluctuation becomes the display center.

A user (orderer) performs an ordering operation by clicking, double-clicking, dragging and dropping, etc. on the board screen 13 using a pointing device such as a mouse.

The board screen display process 15 acquires the position information of the mouse pointer 16. Specifically, when the user moves the mouse pointer 16 onto the board screen 10 when placing an order, the update frequency of the board screen 10 is suppressed (= update speed is reduced), and the display range is scrolled due to price fluctuations. Stop. When the mouse pointer 16 moves away from the board screen 10, the above-described operation is canceled, the display update speed of the screen is returned to normal, and screen scrolling due to price fluctuations is resumed.

In this way, by using an amount and a display method in which a large amount of data display can be visually confirmed by a human, the user can surely recognize and judge information displayed on the board screen 10, and by scrolling the screen. It is possible to prevent an operation mistake in clicking a place different from the intended place, and to safely perform the ordering operation.

Further, by changing the display method only when the mouse pointer 16 is placed on the board screen 10 for performing the ordering operation, real-time data display is realized outside the ordering operation.

In the first embodiment, an ordering operation on the board ordering screen will be described. In the first embodiment, hereinafter, “plate screen” simply includes the entire plate ordering screen.

When the user inputs the security code on the board ordering screen, the board screen display process 15 displays the board information of the brands to be ordered on the board ordering screen.

FIG. 2 is an image diagram when the mouse pointer is outside the board screen in the first embodiment.

When the mouse pointer is outside the board screen, the board screen display process 15 updates the screen of the board screen at an αmsec cycle (0 <α). α is set to 10 msec, for example. When the price fluctuates, the display range is scrolled so that the price is centered on the display.

FIG. 3 is an image diagram before (a) and after (b) a change in the current price when the mouse pointer 16 is outside the board screen in the first embodiment.

Before the change (a) in FIG. 3, the current price of 456 yen (shaded) is the display center. Here, if the current price has changed to 455 yen (down 1 yen), the changed current price 455 yen (shaded) becomes the new display center as shown in FIG. The display range scrolls and the display position of all data changes. For example, the display position where the price is 453 yen is scrolled upward by one line. The same applies to all other lines.

The user determines the order price by operating the mouse and clicking a desired price position on the board screen. When the mouse pointer 16 is moved on the board screen for price determination, the position of the mouse pointer is detected by the board screen display process 15 and the screen update interval is changed to βmsec cycle (0 <α <β), and Stop scrolling the display range due to price fluctuations. β is set to 500 msec, for example.

Note that both α and β are variable depending on the setting. For example, it may be switched according to the transaction time zone.

FIG. 4 is an image diagram when the mouse pointer 16 is on the board screen in the first embodiment.

FIG. 5 is an image diagram of the current price before (c) and after (d) when the mouse pointer 16 is on the board screen in the first embodiment.

Before the change (c) in FIG. 5, the current price of 456 yen (shaded) is the display center. Here, even if the current price changes to 455 yen (1 yen depreciation), the display range does not scroll and the display position of all data does not change as shown in (d) after the change in FIG. The display center is fixed at 456 yen which was the current price before the change. The current price after change of 455 yen is not the display center, that is, the display position is not changed, and is displayed in a shaded manner on the first line of the center line. For example, the display position where the price is 453 yen has not changed. The same applies to all other lines.

In this way, when the pointer approaches a display area where frequent updating (interval of about 10 msec) and scrolling is performed, updating is suppressed (interval of about 500 msec) and scrolling is stopped simultaneously.

In the existing technology, in order to fix or cancel the screen scroll, it is necessary to separately operate controls such as buttons and check boxes. According to the first embodiment, the screen scroll can be fixed / released in the flow of part of the ordering process in which the mouse pointer 16 is placed on the board screen.

That is, based on the position information of the mouse pointer 16, scrolling of the display range is automatically stopped when the mouse pointer 16 is set on the board screen. Therefore, it is possible to suppress an erroneous operation such as clicking an unintended portion by scrolling, in particular, an erroneous operation (erroneous ordering) in which an unexpected price is clicked.

In addition, by slowing down the update speed of the screen drawn at high speed when the mouse pointer is placed on the board screen, the user can correctly recognize the information drawn on the screen and perform an ordering operation I can do it. In addition, the latest information can be displayed by not stopping the screen update.

Since these processes are automatically performed in accordance with an ordering operation of moving the mouse pointer 16 on the board screen, user convenience is improved.

Various information such as price, order quantity, and total number of orders is displayed on the board screen as a large number of values, which are updated as needed in conjunction with market conditions. In the securities market, the beginning of trading time is called “close”, the closing time is called “close”, and the other trading hours are called “zaraba”. In particular, closing is a time zone in which transactions are easy to complete because of the large order quantity.

The user (orderer) needs to make an order by instantaneously judging the market situation from various data displayed on the board screen. Among them, price, order quantity and closing quantity are important factors in judging market conditions.

However, it is difficult to quickly determine the market situation from a large number of numerical values on the board screen updated frequently.

Accordingly, in the second embodiment, the order quantity and the closing quantity are displayed in a graph to improve the visibility of the plate screen and the ordering speed of the user.

FIG. 6 is an image diagram of a board screen according to the graph display method of the second embodiment.

On the board screen, the order quantity (displayed as the number sold or purchased) and the closing quantity (displayed as arguments) are displayed in graphs for each price of sales.

FIG. 7 is a flowchart of the graph display method according to the second embodiment.

The user inputs the securities code of the brand to be ordered on the board ordering screen (S701).

Next, each quantity of the best bid price and the best bid price (the selling price at which buying and selling is most likely to be established) is acquired from the board data distribution server and the like, and the larger value is set as the maximum bid price (S702).

The maximum indicative quantity at the time of acquisition in S702 is set to 70% of the upper limit of the graph. That is, the upper limit (100%) of the graph is determined as a value obtained by multiplying the maximum quotation quantity by 100/70 (S703). (Upper limit of graph (100%) = maximum quotation volume x 100 ÷ 70). Note that the value of 70% here can be set arbitrarily and is not a fixed value.

Next, the (Sell / Buy) order quantity and (Sell / Buy) closing quantity for each price are acquired and compared, and the larger value is set as the maximum quantity for each price (S704).

Then, the ratio (%) of the maximum quantity to the upper limit of the graph is calculated, and a bar graph is displayed for each price (S705). The length of the bar graph represents the maximum quantity of the order quantity and the closing quantity obtained in S704. Furthermore, in order to represent the ratio of the order quantity and the closing quantity in the maximum quantity, the bar graph is displayed in three colors. The first color represents the surplus part of the (Sell / Buy) order quantity, the second color represents the surplus part of the (Sell / Buy) closing quantity, and the third color represents the same part of the order quantity and the closing quantity.

The quantity of the best bid or the best bid is constantly changing, so if the maximum quantity (order quantity or closing quantity) of a price exceeds the upper limit of the graph, or the difference between the upper limit of the graph and the current maximum quantity If the rate exceeds 20% (S706: YES), it is updated by recalculating the upper limit of the graph using the current maximum quantity (S707). Note that the value of 20% of the divergence rate here can be arbitrarily set and is not a fixed value.

Here, one calculation example in the case of FIG. 6 is shown.

As a prerequisite, the minimum trading unit is 1000 (shares), the best bid price is 11000 (shares), the best bid price is 10000 (shares), the price to be calculated is 110 (yen), and the sales order quantity is 12000 (shares) ).

According to S703, the maximum bid price is 11000 (shares) with the best bid price> best bid price, so the upper limit of the graph is 11000 × 100 ÷ 70 = 15714 ≒ 16000 (1000 shares of the minimum trading unit) Rounded up in units).

According to S705, the length of the sales order quantity of the price 110 (yen) (ratio to the upper limit of the graph (%)) is calculated as 12000 ÷ 16000 × 100 = 75 (rounded down).

As described above, in the second embodiment, the order quantity and the closing quantity updated frequently are displayed in a graph. Since the user can confirm the order quantity and the close quantity on the board screen with a graph, the visibility of the board screen is improved and quick order determination can be made.

Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
