Description

Device, method and computer program product for best five-level energy visualization and scaling

The present invention relates to a financial product quotation display technology of a computer program, and more particularly to an optimal five-level volume visualization and scaling device, method and computer program product.

The best five-level buying and selling price and volume (hereinafter referred to as the best five-level) refers to the price and volume of the highest five unexecuted buy orders and the price and volume of the lowest five unexecuted sell orders. This information can help investors make investment decisions and decide the price to buy or sell individual stocks. It can also be used to find out whether the order is executed at the best price. It is usually the information that investors often look at when they are about to place an order in order to grasp the best buying and selling prices.

At present, the best five-level buying and selling information provided by computer program financial quotation software or order placement software is presented in digital form, so that users can clearly understand the highest five-level buy order price and quantity and the lowest five-level sell order price and quantity of a certain financial product. The quantity is expressed as "total cumulative quantity", and users cannot know the detailed situation behind the total cumulative quantity (such as the quantity of each order). For example, prior art 1, Republic of China Patent Publication No. I681354, discloses a "device and method for displaying a continuous number of best five items", which method includes: establishing a connection with a server; receiving an activation instruction of a monitoring condition: downloading a best five item information of a financial product, and generating a best five item view of the financial product based on the best five item information; performing a data comparison and calculating a continuous number of times on the best five item information based on the monitoring condition; generating a continuous number mark, and displaying the continuous number mark at a corresponding position of the best five item information in the best five item view; and updating and displaying the continuous number mark based on the continuous number of times. Figure 4 of the prior art patent specification shows that the best five-level information is presented in digital form. Although digital form can accurately present quantity and price, the human brain is more sensitive to images, that is, the brain recognizes images more efficiently than numbers. Therefore, the best five-level information of the prior art lacks image representation, which makes it difficult for users to quickly identify and compare the difference in quantity of different price levels, for example: the comparison between the quantity of the first-level buyer's price and the quantity of the first-level seller's price, which one has a stronger quantity.

Furthermore, the prior art presents the total cumulative volume of each of the five best tiers in digital form, which does not allow users to distinguish between large orders (large single orders) and small orders (small single orders). In other words, the prior art lacks a graphical representation of large orders and small orders, and also lacks the technology to mark each order separately. Therefore, users cannot tell from the total cumulative volume in digital form how many large orders and small orders there are, nor can they tell whether the current buying and selling orders are mostly retail investors (small orders) or corporate or large investors (large orders). In addition, fake orders are often placed in the market to create the illusion of strong buying or selling pressure, thereby attracting more investors to enter the market. When the fake order is about to be executed, the order is quickly withdrawn (deleted) to raise or lower the stock price. From the best five information of the previous technique one, it is impossible to see whether there is a fake order or not, nor can it be seen that the fake order changes.

Due to the limitation of previous technology, users (investors) cannot see the volume change of the best five levels or the ratio of large orders to small orders through the visual volume line chart on the screen, and there is no best five levels of volume line chart that can be arbitrarily enlarged or reduced to allow users to perform scaling operations according to their needs. In other words, the technical purpose of the previous technology is not about the visualization and scaling technology of the best five levels of volume.

Therefore, it is necessary to improve the previous technical methods and propose a technology that uses the best five-level volume visualization and scaling by using the resources of hardware and software to make the best five-level volume visualization technology and can be scaled at will. When users view the best five levels of a certain stock on the screen, they can quickly identify the situation of large and small orders at each level through the best five-level volume line chart, and can The zoom operation is performed according to the needs of the user. For example, after zooming in on the energy line chart, more unit quantity detail information can be viewed. In particular, through the visualization effect of the navigation bar 38, the user can easily know the corresponding position and corresponding zoom ratio of the "current energy line chart 32 in the screen visible range 44" and the "overall energy line chart 32 after zooming", which helps the user make investment decisions to make up for the shortcomings of previous technologies.

In view of this, the present invention proposes an apparatus, method and computer program product for best five-level volume visualization and zooming. A corresponding volume line chart is drawn next to each order price in the best five-level view.

Referring to FIG. 1 and FIG. 2, the system function block diagram of the device 10 for visualizing and scaling the best five-level energy and the system function block diagram of an embodiment of the application 20 of the present invention, the legend only lists the core modules related to a preferred embodiment of the present invention, and the remaining modules are omitted and not described. The application 20 of the embodiment is executed on the device 10 for visualizing and scaling the best five-level energy of the present invention. In an embodiment of the present invention, the device 10 for visualizing and scaling the best five-level energy of the present invention includes: one or more processors 12, a memory 14, a screen 16 and a communication module 18. The memory 14 stores the application 20; the processor 12 executes a plurality of program instructions included in the application 20, and implements the following modules in a hardware and software collaborative operation manner: a login verification module 22, a best five-level quotation module 24, a data visualization module 26, and a line chart zoom module 28; the screen 16 is used to display the graphical user interface (GUI) of the application 20, and in some embodiments further includes: processing touch operation events, such as being used in touch-screen devices such as smart phones, tablet computers, etc.; the communication module 18 is used to establish an Internet network connection, such as: wired broadband, WLAN (Wi-Fi, etc.), mobile communication networks (such as 3G, 4G, 5G, etc.), etc.

Continuing to refer to FIG. 2, a system function block diagram of an application program 20 of an embodiment of the present invention includes: a login verification module 22, a best five-level quotation module 24, a data visualization module 26 and a line chart zoom module 28. The figure only lists the core modules related to a preferred embodiment of the present invention, and the remaining modules are omitted and not described, for example: an international financial quotation module, a self-selected quotation module, a detailed quotation module, a stock news module, an accounting module, etc.

The login verification module 22 is used to establish a connection with the server and perform login verification. In some embodiments, a token is downloaded and stored in the memory 14 after successful login verification. Login verification includes multiple methods. In some embodiments, identity verification is performed using an account and password; in some embodiments, identity verification is performed using the user's biometrics, such as fingerprint recognition or Face ID recognition.

The best five-level quote module 24 is used to download the quote message of the financial product from the quote server, and then generate the best five-level views 30a, 30b (Figure 4, Figure 5) corresponding to the financial product based on the downloaded quote message. The quote message includes the transaction price, transaction volume, and multiple order prices and corresponding multiple order quantities of the financial product. One order price and corresponding order quantity correspond to one order. For example, a quote message of a financial product includes the transaction price, transaction volume, the first-tier sell price and the first-tier sell quantity, the second-tier sell price and the second-tier sell quantity, the third-tier sell price and the third-tier sell quantity, the fourth-tier sell price and the fourth-tier sell quantity, the fifth-tier sell price and the fifth-tier sell quantity, the first-tier buy price and the first-tier buy quantity, the second-tier buy price and the second-tier buy quantity, the third-tier buy price and the third-tier buy quantity, the fourth-tier buy price and the fourth-tier buy quantity, the fifth-tier buy price and the fifth-tier buy quantity. An entrustment price and the corresponding entrustment quantity in the same quote message is an entrustment order. As in the above example: the first order price and the first order quantity are one order, and the second order price and the second order quantity are another order... and so on. Each quotation message has a unique transmission sequence number; in some embodiments, one transmission sequence number can correspond to multiple different orders (including the order price and the order quantity), that is, these order prices and order quantities are transmitted through the same quotation message; in some embodiments, multiple orders in the same quotation message have their own corresponding unique order sequence numbers, that is, one transmission sequence number can correspond to multiple order sequence numbers.

The data visualization module 26 generates a respective volume line chart corresponding to each order price in the best five price quotes of the financial product and displays the corresponding volume line chart in the best five price views 30a and 30b. For example, there are five buy orders and five sell orders in the best five price quotes, so there are a total of ten corresponding volume line charts 32 (Figure 3 and Figure 4). The orders of the same buying and selling type and the same order price are drawn on the same volume line chart 32. The volume line chart 32 is composed of a plurality of horizontal line segments in a time sequence. Each line segment represents an order. The adjacent line segments on the left and right of the same volume line chart 32 are separated by separators 40 (as shown in Figure 9) to distinguish different orders. For example, a short vertical line segment, symbol, text, etc. are used as separators. That is to say, the volume-energy line chart 32 is formed by a plurality of quote messages in chronological order (i.e., the time sequence of receiving the order by the exchange) successively updating the line segments (i.e., the order in the new quote message), and the order of the quote message can be determined by the transmission sequence number of the quote message. At the initial time, the length of the line segment is generated according to the order quantity of the order and the dynamic adjustment method of the optimal ratio. The dynamic adjustment method of the optimal ratio is to dynamically adjust the scale according to the width of the screen visible range 44 of the best five-level view 30a, 30b and the longest one among the volume-energy line chart 32 so that the volume-energy line chart 32 can be fully presented in the screen visible range 44 (i.e., the complete volume-energy line chart 32 can be viewed without sliding or scrolling). The length of the line segment and the order quantity have a certain ratio. The longer the line segment, the larger the corresponding order quantity. However, the ratio may change at different times due to the increase or decrease of the order quantity. For example, the application 20 used in a smart phone needs to dynamically adjust the optimal ratio of the line segment length and the order quantity according to the width of the mobile phone screen 16. In some embodiments, the ratio between the length of the line segment and the order quantity is determined according to the largest order quantity in all the volume energy line charts 32 in the best five-level view 30a, 30b. For example: two different financial products A and financial product B are displayed in the application 20 of the same device 10. If the largest number of orders in all the volume line charts 32 in the best five-level view 30a, 30b of "financial product A" is 100, and the largest number of orders in all the volume line charts 32 in the best five-level view 30a, 30b of "financial product B" is 499, the present invention uses different ratios to display the line lengths of the two financial products. For another example: in all the volume line charts 32 in the best five-level view 30a, 30b of the same "financial product A", the largest number of orders in the previous period is 100, and the largest number of orders in the next period is 499, the present invention also uses different ratios to display the line lengths of the same financial product in the two periods. That is, the data visualization module 26 of the present invention can dynamically adjust the ratio of the line segment length to the commission quantity according to the situation. In some embodiments, when the line graph scaling module 28 receives a zoom-in instruction or a zoom-out instruction, the data visualization module 26 stops executing the dynamic adjustment method of the optimal ratio and is replaced by the display ratio specified in the zoom-in instruction or the zoom-out instruction, until the line graph scaling module 28 receives a reset instruction and then resumes executing the dynamic adjustment method of the optimal ratio. The data visualization module 26 also includes a navigation bar (i.e., a preview bar, a navigation bar) 38 that generates a corresponding volume line chart 32 in the best five-level views 30a and 30b to instantly compare the corresponding position and the corresponding zoom ratio of the current volume line chart 32 in the screen visible range 44. In other words, through the visualization effect of the navigation bar 38, the user can easily know the corresponding position and the corresponding zoom ratio of the "current volume line chart 32 in the screen visible range 44" and the "overall volume line chart 32 after zooming" by visually observing. The volume chart 32 is directional when updated. One end (front end) of the volume chart 32 is the earliest data (i.e., the order that has been waiting in line the longest will be executed faster than other orders in the same volume chart), while the other end (back end) is the latest updated data.

In some embodiments, the order in the quotation message does not carry the corresponding order sequence number. The present invention uses two consecutive quotation messages in time sequence to calculate the increase or decrease in the corresponding order quantity of the same order price. For example, "an updated quotation message" and "a previous quotation message" are two consecutive quotation messages in time sequence, which can be identified by their respective transmission sequence numbers. In addition, when there is a reduction in the order quantity for the first order price, in addition to comparing and calculating the reduction in both the first order buy quantity and the first order sell quantity, it is also necessary to compare the transaction price and transaction volume in the "updated quotation message" to confirm whether the reduction in the first order quantity is a reduction order or a transaction. In some embodiments, the transaction volume corresponding to the transaction price in the quotation message is the cumulative transaction volume, and two consecutive quotation messages in time sequence need to be compared to calculate the transaction volume in the "updated quotation message". When the order quantity of the same order price in the "updated quotation message" increases (this is compared with the order quantity of the same order price in the "previous quotation message", if the order quantity is greater than the previous one, it is "increase"), it is regarded as a new order, that is, a separator is generated at the end of the corresponding volume line chart 32, and then a line segment representing the new order is generated and placed after the separator, and the length of the line segment is proportional to the increase. When the order quantity of the same order price in the "updated quotation message" has a deletion or reduction (this is compared with the order quantity of the same order price in the "previous quotation message", if the order quantity is less than the previous one, it is a "deletion or reduction"), it is regarded as a deletion of an old order, that is, the line segment corresponding to the order quantity of the same order price that meets the same deletion or reduction will be deleted. For example, if the reduction in quantity of a certain order price in the "updated quotation message" is 199 sheets, the data visualization module 26 will compare and search for the line segment with the order quantity of 199 sheets in the existing order price and delete it, and the vacant position after deletion will be filled by the next line segment to continue the previous line segment. If the order quantity that completely meets the reduction in quantity is not found, the line segment corresponding to the order quantity in the order price that is greater than and close to the reduction in quantity will be shortened to the corresponding proportion. For example, if the reduction is 199 pieces, and there is no order with the same quantity, but there is an order with 200 pieces, the line segment corresponding to the 200 pieces will be shortened to the length of 1 piece (i.e., 200-199=1). When the quantity of a certain order price is reduced, if the reduction is small (e.g., 1 piece), it is very likely that multiple orders with the same quantity will be found at the same time. In some embodiments, the data visualization module 26 deletes the earliest order with the same order quantity; in some embodiments, the data visualization module 26 deletes the latest order with the same order quantity; in some embodiments, the data visualization module 26 deletes any order with the same order quantity. When the order quantity of a certain order price has a deletion quantity and there are no orders with the same order quantity, but there are multiple orders with a quantity greater than the deletion quantity, in some embodiments, the data visualization module 26 deletes the earliest order with a quantity greater than the deletion quantity. When the order quantity of a certain order price is deleted or reduced, especially when the amount is small, since the quotation message of this embodiment does not provide a corresponding order number for each order, this embodiment deletes or reduces the line segment of a certain order by estimation and guesswork. Therefore, this technical method has the possibility of error (due to the high probability of duplication). However, the error rate is small for large amount deletions (due to the low probability of duplication), so the volume line chart of this embodiment still has a considerable degree of observation significance for orders with large order quantities (such as orders of legal persons).

In some embodiments, each order in the quotation message (i.e., each order price and the corresponding order quantity) is accompanied by a corresponding order sequence number. When the data visualization module 26 generates the respective volume line charts corresponding to each order price in the quotation message according to the best five-level quotation message, the order sequence number of each line segment (i.e., representing an order) is recorded at the same time. When there is a deletion order, the corresponding line segment can be directly deleted or shortened to the length of the corresponding quantity according to the order sequence number of the order. That is to say, this embodiment draws, deletes, and shortens the corresponding line segments in the volume line chart according to the order sequence number, so that the volume line chart can accurately present the queue situation of the real order.

In some embodiments, the data visualization module 26 further includes: marking the corresponding order quantity 46 with a number at the relevant position of the corresponding line segment, as shown in FIG. 10A , where the so-called "the relevant position of the corresponding line segment" refers to the position adjacent to the line segment and the position of the corresponding line segment can be easily identified (i.e., "will not be mistaken as corresponding to another line segment"). For example: if the order quantity of a certain order is 96, then "96" is marked at the relevant position of the corresponding line segment (e.g., above or below the line segment). In some embodiments, the volume line chart 32 is divided into a buy side volume line chart 34 (i.e., the collective name of all volume line charts of the buy side of each level) and a sell side volume line chart 36 (i.e., the collective name of all volume line charts of the sell side of each level) according to the corresponding buy and sell categories of the orders, as shown in Figure 4. Further, in some embodiments of the present invention, the data visualization module 26 further includes: receiving an arrangement display switching instruction (generated when the arrangement display option button 48 is clicked) to present the arrangement display of the buy side volume line chart 34 and the sell side volume line chart 36 in the best five-level views 30a and 30b. The arrangement display is selected from: horizontal arrangement (i.e., the buy volume line chart 34 and the sell volume line chart 36 are arranged symmetrically from left to right), vertical arrangement (i.e., the sell volume line chart 36 and the buy volume line chart 34 are arranged symmetrically from top to bottom), single display of the buy volume line chart 34 (i.e., only the buy volume line chart 34 is displayed on the screen 16), and single display of the sell volume line chart 36 (i.e., only the sell volume line chart 36 is displayed on the screen 16). The so-called "symmetry" mentioned above means that the first-tier buy order arrangement is symmetrical to the first-tier sell order, the second-tier buy order arrangement is symmetrical to the second-tier sell order, the third-tier buy order arrangement is symmetrical to the third-tier sell order, and so on. In some embodiments, the data update directionality of the buy volume line chart 34 and the sell volume line chart 36 in the horizontal arrangement is mirror symmetrical, that is, the front ends of the buy volume line chart 34 and the sell volume line chart 36 (that is, the earliest order) are both located on the inner side of the best five-level view 30a, and the ends of the buy volume line chart 34 and the sell volume line chart 36 (that is, the last updated order) are both located on the outer side of the best five-level view 30a, as shown in Figure 4. In some embodiments, the data update directionality of the buy volume line chart 34 and the sell volume line chart 36 in the vertical arrangement is the same, that is, the front ends of the buy volume line chart 34 and the sell volume line chart 36 are both located on the right side of the best five-level view 30b, and the ends of the buy volume line chart and the sell volume line chart are both located on the left side of the best five-level view 30b, as shown in Figure 5A.

The line graph zoom module 28 receives a zoom-in instruction to enlarge the display ratio of the energy line graph 32, and receives a zoom-out instruction to reduce the display ratio of the energy line graph 32. The receiving method of the zoom-in instruction and the zoom-out instruction is selected from: two-finger touch (i.e., sliding two fingers apart outward is a zoom-in instruction, and sliding two fingers together inward is a zoom-out instruction), a zoom menu (e.g., in the menu, the "+" plus sign option is used as the zoom-in function, and the "-" minus sign option is used as the zoom-out function, which is applicable to touch and non-touch devices, not depicted), a zoom key (e.g., a virtual key with "+" plus sign option as zoom in function, "-" minus sign option as zoom out function, applicable to touch and non-touch devices, not depicted), mouse wheel operation (i.e., physical mouse scroll wheel or touch bar, applicable to computer version, not depicted), keyboard shortcuts (i.e., physical keyboard keys, applicable to computer version, not depicted) and remote control (applicable to smart TV version, not depicted), etc. Regardless of which of the above methods the user uses to generate a zoom in command or a zoom out command, the operation may also include specifying the display ratio to be enlarged or reduced. For example, when two fingers are slid outward with two fingers apart, the distance the two fingers slide determines the display ratio to be enlarged. For another example, when the mouse wheel is used, the distance the wheel is rotated determines the display ratio to be enlarged or reduced. In addition, the "forward rotation" and "backward rotation" of the wheel control the zoom in and zoom out functions respectively. When the line graph zoom module 28 receives the zoom-in command or the zoom-out command, it triggers the data visualization module 26 to redraw the entire energy-volume line graph 32 according to the display ratio specified by the user, and simultaneously updates the corresponding position and zoom ratio of the navigation bar 38 according to the redrawn entire energy-volume line graph 32. That is to say, at the beginning, the volume-energy line chart 32 is presented in the best five-level view 30a, 30b at the best ratio. At this time, the navigation bar 38 includes a horizontal long bar frame and a "navigation block" filled with a specific color (or a specific pattern, such as diagonal stripes) in the middle. The long bar frame represents the "length of the overall volume-energy line chart 32 after zooming", and the navigation block represents the "length of the volume-energy line chart 32 in the visible range 44 of the screen". When the volume-energy line chart 32 is zoomed in to the specified display ratio, the navigation block in the navigation bar 38 is shortened in the horizontal direction to the "corresponding zoom ratio" (that is, the length of the navigation block: the length of the long bar frame = "the length of the volume-energy line chart 32 in the visible range 44 of the screen": In some embodiments, the line chart zoom module 28 further includes: receiving a movement instruction to horizontally move the overall energy volume line chart 32 to the end position of the corresponding movement instruction in the screen visible range 44. For example, after the energy chart 32 is enlarged, part of the chart data is outside the visible range 44 of the screen. The user needs to use a movement command to move the chart data outside the visible range 44 of the screen into the visible range 44 of the screen (only horizontal movement); on a touch device, a multi-finger touch dragging method can be used for operation, on a non-touch device, a mouse dragging method can be used for operation, and on a smart TV, a simulated mouse dragging method of a remote control can be used for operation. A move instruction includes a starting position and an ending position. When a move instruction is generated, the starting position of the receiving move instruction (such as the initial position of the touch) can be regarded as the "operation center point of the overall energy and volume line chart 32". This "operation center point of the overall energy and volume line chart 32" will eventually be moved horizontally to the ending position of the move instruction (located in the screen visible range 44). At the same time, the data visualization module 26 will synchronize and update the corresponding position of the navigation block in the navigation bar 38 in real time, thereby completing the execution of the move instruction. The "command receiving target" (i.e., the touch area of the touch command, or the operating area of the mouse wheel) for receiving the move command, the zoom in command, the zoom out command, and the move command is selected from: the best five-speed views 30a, 30b, the navigation bar 38, or both the best five-speed views 30a, 30b and the navigation bar 38. In some embodiments, the navigation bar 38 further includes: a corresponding reset button 42 for receiving a reset command so that the line chart zoom module 28 resets the display ratio of the overall volume line chart 32 and restores it to the optimal ratio. At the same time, the data visualization module 26 redraws the overall volume line chart 32 according to the optimal ratio, so that the overall volume line chart 32 can be fully presented in the visible area 44 of the screen, and updates the corresponding zoom ratio of the navigation bar 38 according to the redrawn overall volume line chart 32 (at this time, the navigation block fills the entire long bar frame, as shown in Figures 3 and 5A). In some embodiments, when the line chart zoom module 28 receives a zoom command, it triggers the data visualization module 26 to redraw the overall energy line chart 32 according to the display ratio, and when the individual line segments have a sufficient length after zooming in to accommodate the annotation of the corresponding individual commission quantities, the data visualization module 26 further includes: annotating the corresponding commission quantities at the corresponding related positions, that is, this embodiment determines the length of the line segments after zooming in, the font size of the annotation quantity, the length of the annotation quantity (such as: 2 digits or 3 digits) and other factors to determine the length of the line segments above which there is sufficient space before performing the annotation work. That is, when the line segment is enlarged to a sufficient length, the user can see more annotation information (i.e., the number of commissions of each line segment). For example, when the line segment is enlarged to the maximum ratio, even the number of commissions of only "1" will be marked. In some embodiments, when the line chart zoom module 28 receives the zoom instruction, it triggers the data visualization module 26 to redraw the volume line chart 32 according to the display ratio, so that the line segments of the entire volume line chart 32 are extended in the horizontal direction (i.e., enlarged and expanded in the horizontal direction), while the vertical separation marks still maintain the original size and are not enlarged. In some embodiments, when the line chart zoom module 28 receives a zoom-out command, the data visualization module 26 is triggered to redraw the volume line chart 32 according to the display ratio, and when the line segment originally marked with the order quantity does not have sufficient length to accommodate the corresponding order quantity after being zoomed out, the corresponding order quantity is hidden in the line segment that does not have sufficient length. For example, if a line segment marked with the order quantity is enlarged, when a zoom-out command is received, the order quantity corresponding to the line segment will be hidden because the line segment is redrawn according to the display ratio and does not have sufficient length.

Referring to Figure 3, a schematic diagram of the screen 16 of the computer version of the best five-level volume line chart 32 of an embodiment of the present invention illustrates the graphical user interface of the present invention displaying an embodiment application 20 on the screen 16. The diagram of this embodiment is illustrated by taking the screen style of a personal computer as an example. The present invention is not limited to use in personal computers. The present invention can also be used in devices such as smart TVs, tablet computers, smart phones, handheld stock machines, personal digital assistants, etc. The illustration is that a personal computer (the best five-level volume visualization and zooming device 10) executes the application 20 of the present invention (financial trading software or financial quotation software) and displays the quotation information of various financial products, among which the best five-level view 30a is at the bottom right of the screen 16. The best five-level view 30a is generated by the best five-level quote module 24 according to the best five-level quote message of a single financial product (the example is "TSMC"). Then, the data visualization module 26 generates a volume line chart 32 corresponding to each order price in the quote message according to the best five-level quote message and displays it in the best five-level view 30a. The main technical feature of the present invention is that the volume line chart 32 corresponding to each order price and the navigation bar 38 are generated and added in the best five-level view 30a.

Referring to FIG. 4 , a schematic diagram of the screen visible range 44 of the horizontal best five-level volume energy line graph 32 of the embodiment of the present invention is shown. The diagram illustrates that the present invention adds an arrangement display option button 48 (clicking it will generate an arrangement display switching command) in the best five-level view 30a for the user to select the arrangement display of the volume energy line graph. The illustration is arranged horizontally, that is, the buy volume chart 34 and the sell volume chart 36 are arranged symmetrically. In this horizontal arrangement, the data update direction of the buy volume chart 34 and the sell volume chart 36 is mirror symmetrical, that is, the front ends of the buy volume chart 34 and the sell volume chart 36 (that is, the earliest order) are both located inside the best five-level view 30a, and the ends of the buy volume chart 34 and the sell volume chart 36 (that is, the last updated order) are both located outside the best five-level view 30a. The navigation bar 38 is used to compare the zoom status of the overall volume chart 32 and the corresponding position. The “rounded dotted frame” in the legend is only used to explain what the buy volume line chart 34 and the sell volume line chart 36 refer to, respectively, and the “one-point link frame” is used to explain the screen visible range 44. When the application 20 is actually operated, neither the rounded dotted frame nor the one-point link frame will be displayed on the screen 16.

Referring to FIG. 5A , a schematic diagram (I) of the screen visible range 44 of the vertical best five-level volume line chart of the embodiment of the present invention, the present embodiment is arranged vertically, that is, the sell-side volume line chart 36 and the buy-side volume line chart 34 are arranged symmetrically from top to bottom, and the arrangement order of the volume line chart 32 from top to bottom is: fifth-level sell order, fourth-level sell order, third-level sell order, second-level sell order, first-level sell order, first-level buy order, second-level buy order, third-level buy order, fourth-level buy order and fifth-level buy order. In the vertical arrangement, the data update directionality of the buy volume line chart 34 and the sell volume line chart 36 is the same, that is, the front ends of the buy volume line chart 34 and the sell volume line chart 36 are both located on the right side of the best five-level view 30b, and the ends of the buy volume line chart 34 and the sell volume line chart 36 are both located on the left side of the best five-level view 30b. The legend illustrates that at the initial time (i.e., after switching to the best five-level view 30b and without zooming in the energy line chart 32 with a zoom command), the present invention adopts a dynamic adjustment method of the best ratio so that the overall energy line chart 32 is fully presented in the screen visible range 44 of the best five-level view 30b. At this time, the navigation bar 38 is filled with a long bar frame with diagonal stripes (representing the navigation block). The long bar frame represents the "overall energy line chart 32", and the navigation block represents the "current energy line chart 32 in the screen visible range 44". Among them, "the navigation block fills the long bar frame" means that the lengths of the "overall energy line chart 32" and the "current energy line chart 32 in the screen visible range 44" are equal. This embodiment is suitable for use in smart phones or other mobile devices with a slightly smaller screen 16 or a vertical screen display.

Referring to FIG. 5B , the schematic diagram (II) of the screen visible range 44 of the vertical best five-level volume energy line chart of the embodiment of the present invention, the illustration is to illustrate that after the entire volume energy line chart 32 is enlarged by the enlargement command, a part of the volume energy line chart 32 is already outside the screen visible range 44; at this time, the state of the navigation bar 38 is that the navigation block only occupies more than half of the right side of the long bar frame, that is, the navigation block is shortened in the horizontal direction to the "corresponding zoom ratio" (that is, the length of the navigation block: the length of the long bar frame = "the current length of the volume energy line chart 32 in the screen visible range 44": "The length of the overall volume energy line chart 32 after zooming"); also, the presentation position of the navigation block in the long bar frame represents the corresponding position of the "current volume energy line chart 32 in the screen visible range 44" in the "overall volume energy line chart 32 after zooming".

Referring to FIG. 6A, the screen 16 of the vertical best five-level volume energy line chart of the mobile phone embodiment of the present invention is schematically shown (I). The diagram of the present embodiment is illustrated by taking the screen style of a smart phone as an example. The data display of the best five-level view 30b in the diagram is the same as that of FIG. 5B (however, the diagram does not depict the data outside the screen visible range 44). The present embodiment of the present invention illustrates that on a small screen device such as a smart phone, the navigation bar 38 of the present invention allows the user to easily know the corresponding position and corresponding zoom ratio of the "current volume energy line chart 32 in the screen visible range 44" and the "zoomed overall volume energy line chart 32".

Referring to FIG. 6B, the screen 16 of the vertical best five-level volume line chart of the mobile phone version of the present invention is shown in FIG. 6A. The example is to illustrate that when the user slides the overall volume line chart 32 horizontally with a movement command (such as touch sliding) in FIG. 6A to view the data outside the screen visible range 44 (left side), the navigation block of the navigation bar 38 will also change the display position to the left side of the long bar frame. Since the data in the example is displayed at the leftmost end of the overall volume line chart 32, and the volume line chart 32 of the first level sell order and the first level buy order has a smaller total amount of original orders, there is no data on this screen.

Referring to FIG. 6C , the screen 16 diagram of the vertical optimal five-level volume line chart of the mobile phone version of the embodiment of the present invention (III) is shown. The diagram illustrates that if the user is in FIG. 6A or FIG. 6B and wants to restore the initial optimal proportional dynamic adjustment method (i.e., presenting the complete volume line chart 32 in the visible range 44 of the screen), he only needs to press the reset button 42 (generate a reset command) as shown in the diagram.

Referring to FIG. 7 , a schematic diagram of the screen 16 of the mobile phone version of the embodiment of the present invention showing only the buy side volume line chart 34 is shown. The figure illustrates that the arrangement of the best five-level view 30b of the present embodiment shows only the buy side volume line chart 34, and the navigation block of the navigation bar 38 is located at the rightmost end of the long bar, indicating that the screen visible range 44 is the right end portion of the buy side volume line chart 34.

Referring to FIG. 8, a schematic diagram of the screen 16 of the mobile phone version of the embodiment of the present invention showing only the sell-side volume line chart 36, the legend illustrates that the arrangement display of the best five-level view 30b of the present embodiment only has the sell-side volume line chart 36, and the arrangement order of the sell-side volume line chart 36 in the present embodiment is different from the sell-side volume line chart 36 in FIG. 6A. The arrangement order of the volume line chart 32 from top to bottom in the present embodiment is: first-level sell order, second-level sell order, third-level sell order, fourth-level sell order, fifth-level sell order, which is exactly the opposite of the order in FIG. 6. This arrangement display is also suitable for mobile devices with slightly smaller screens 16.

Refer to Figure 9, which is an enlarged schematic diagram of the volume chart 32 of the embodiment of the present invention. The figure is illustrated by the volume chart 32 of the second-tier buy order (order price "480.0"). For easy identification, it is illustrated by an enlarged diagram of a single volume chart 32. This enlarged diagram does not refer to "an enlarged diagram redrawn by an enlargement instruction". Different orders are distinguished by separators 40 between the adjacent line segments on the left and right. The separators 40 in the figure are short straight line segments. When there are dense short line segments somewhere on the volume chart 32, it means that there are many small orders there, that is, there are mostly retail orders there. In addition, the legend labels numbers representing the order quantity above some of the line segments in the volume line chart 32. In some embodiments, the application 20 or the memory 14 stores the threshold of "large order". When the line segment has a sufficient length to accommodate the label of the order quantity corresponding to the large order, the corresponding order quantity is labeled at the corresponding relevant position. The legend labels the line segment of "order quantity greater than 20" (i.e., the threshold of large order is "20") with numbers.

Referring to FIG. 10A, the screen 16 diagram (I) of the mobile version of the buy side volume line chart 34 and the order quantity 46 mark of the embodiment of the present invention, this embodiment adds the order quantity mark to the line segments of some orders in FIG. 7 (the example is to add the mark to the line segments with the order quantity greater than "20"). The user can easily identify the large orders in the volume line chart 32 of each level from the example (the application 20 or the memory 14 stores the threshold value of the large order).

Referring to FIG. 10B , the screen 16 diagram (II) of the mobile version of the buy side volume line chart 34 and the order quantity 46 marking of the embodiment of the present invention, the processing of this embodiment is different from that of the embodiment of FIG. 10A in that: when the zoom-in instruction is received and the overall volume line chart 32 is redrawn, and the individual line segments have a sufficient length after being enlarged to accommodate the corresponding individual order quantity 46 marking, the corresponding related positions of the line segments (the "related positions" in the legend are above the line segments) will all be marked with the corresponding order quantity 46. In other words, when the display ratio is enlarged to the maximum, even the line segment with the smallest quantity will be marked with the order quantity 46.

Referring to FIG. 11, the present invention is applied to the screen 16 of the vertical best five levels (also known as "five-level market") 30b of mainland stocks. The legend illustrates that the best five-level view 30b of "Minsheng Bank" arranges the buy volume line chart 34 and the sell volume line chart 36 in a vertical manner, and the data update direction of the two is the same. The data update direction of this embodiment is just opposite to that of FIG. 6. In this embodiment, the front ends (earliest data) of the buy volume line chart 34 and the sell volume line chart 36 are both located on the left side of the best five-level view 30b, and the ends (latest updated data) of the buy volume line chart 34 and the sell volume line chart 36 are both located on the right side of the best five-level view 30b. The illustration adopts the best proportion dynamic adjustment method (i.e., the complete volume line chart 32 is presented in the visible range 44 of the screen). At this time, the navigation area of the navigation bar 38 is filled with long bars. In addition, the illustration assumes that the threshold of the large order is "2000", so only a few line segments are marked with the order quantity 46.

Referring to FIG. 12, an operation flow chart of an application 20 according to an embodiment of the present invention, a user uses a device (such as a personal computer/smart TV/smart phone/tablet computer/stock machine) to execute the application 20 and then switches to the best five-level view 30a, 30b of a certain financial product and executes the operation flow of the zoom command, please refer to FIG. 1, FIG. 2, FIG. 3, FIG. 6A and FIG. 6C at the same time, which includes:

Step S101: Execute the application 20 of an embodiment of the present invention on the device 10. The user executes the application 20 (stock quotation software or stock trading software) of the present invention on the device 10 with the best five-level volume visualization and zooming.

Step S102: Establishing a connection with the server and performing login verification. After the communication module 18 establishes an Internet connection, the login verification module 22 establishes a connection with the server (i.e., the login server) to perform a login verification operation. In some embodiments, after the verification is successful, a token is downloaded and stored in the memory 14. In some embodiments, the user performs identity verification with an account and password; in some embodiments, the user performs identity verification with a biometric feature, such as fingerprint recognition or Face ID recognition; in some embodiments, the user performs identity verification with an electronic certificate.

Step S103: Download the best five-level quote message of the financial product and generate the best five-level views 30a and 30b. After logging in, if the user wants to view the best five-level information of "TSMC", the user switches to the best five-level views 30a and 30b by operating the menu (not depicted), and the best five-level quote module 24 downloads the best five-level quote message of "TSMC" from the server (quote server) and stores it in the memory 14, and then the best five-level quote module 24 generates the best five-level view 30a. In some embodiments, a best five-level quote message may include multiple orders (including order prices and order quantities), and a best five-level quote message has a unique transmission serial number, and all orders of the same best five-level quote message share the same transmission serial number. In some embodiments, multiple orders in the same quotation message have their own corresponding unique order serial numbers, that is, one transmission serial number can correspond to multiple order serial numbers.

Step S104: Generate the respective volume line graphs 32 corresponding to the entrustment price according to the quotation message and display them in the best five-level view 30a, 30b. After the previous step downloads the best five-level quotation message, the data visualization module 26 then generates the respective volume line graphs 32 corresponding to each entrustment price in the quotation message according to the best five-level quotation message and displays them in the best five-level view 30a, 30b. The computer version is shown in Figure 3, and the mobile phone version is shown in Figure 6C.

Step S105: Generate a navigation bar 38 corresponding to the overall volume-energy line graph 32 in the best five-level views 30a and 30b. The data visualization module 26 generates a navigation bar 38 corresponding to the overall volume-energy line graph 32 in the best five-level views 30a and 30b to instantly compare the corresponding position and corresponding zoom ratio of the current volume-energy line graph 32 in the screen visible range 44.

Step S106: Receive a zoom command to enlarge the display ratio of the overall energy line graph 32. The line graph zoom module 28 receives a zoom command to enlarge the display ratio of the energy line graph 32, for example: the user operates on a smart phone by two-finger touch (generating a zoom command), or operates on a computer by a mouse wheel ("forward rotation" generates a zoom command).

Step S107: Redraw the whole volume line graph according to the display ratio, and update the navigation bar 38 at the same time. After receiving the zoom command, the line graph zoom module 28 triggers the data visualization module 26 to redraw the whole volume line graph 32 according to the display ratio specified by the user, and at the same time updates the corresponding position and zoom ratio of the navigation bar 38 according to the redrawn whole volume line graph 32. As shown in FIG. 6A.

Furthermore, some of the steps may be performed on more than one processor, such as when a microprocessor and a peripheral interface processor in the device of the present invention work in concert. In addition, one or more blocks or combinations of blocks in the flowchart may be performed simultaneously with other blocks or combinations of blocks, or even in a different order than shown, without departing from the scope or spirit of the present invention.

Therefore, the blocks of the flowchart of the present invention support component combinations for performing specified actions or technical effects, step combinations for performing specified actions or technical effects, and program instruction components for performing specified actions or technical effects. It can also be understood that these specified actions or technical effects are implemented by special-purpose hardware systems or special-purpose hardware and program instructions in conjunction with each block of the flowchart of the present invention and the block combination of the flowchart.

In summary, the present invention proposes a technology for visualizing and zooming the best five-level volume, which solves the problem that the previous technology cannot allow users to identify large orders (single orders with larger quantities) and small orders (single orders with smaller quantities) in each of the best five levels with a visualized volume line chart. It also solves the problem that the previous technology lacks the best five-level volume line chart that can be arbitrarily enlarged or reduced, allowing users to perform zoom operations as needed. Through the present invention, users can quickly identify the situation of large orders and small orders in each level through the visualized best five-level volume line chart, and can arbitrarily enlarge the best five-level volume line chart to view further information, which makes up for the shortcomings of the previous technology.

Although the technical content of the present invention has been disclosed as above with the preferred embodiments, it is not intended to limit the present invention. Any slight changes and modifications made by anyone skilled in the art without departing from the spirit of the present invention should be included in the scope of the present invention.
