Description

Best five-level energy visualization device, method and computer program product

The present invention relates to a financial product quotation display technology of a computer program, and in particular to a device, method and computer program product for visualizing the best five-level volume.

The best five-level buying and selling price and volume (hereinafter referred to as the best five-level) refers to the price and number of the highest five-level buy orders that have not been executed, and the price and number of the lowest five-level sell orders that have not been executed. This information can help investors make investment decisions and decide the price to buy or sell individual stocks, and can also know whether the entrusted transaction 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 price.

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 number I681354, discloses a "device and method for displaying a continuous number mark of the best five grades", the method comprising: establishing a connection with a server; receiving an activation instruction of a monitoring condition: downloading a best five grade information of a financial product, generating a best five grade view of the financial product according to the best five grade information; performing a data comparison and calculating a continuous number of times on the best five grade information according to the monitoring condition; generating a continuous number mark, displaying the continuous number mark at a corresponding position of the best five grade information in the best five grade view; and updating and displaying the continuous number mark according to the continuous number of times. Figure 4 of the patent specification of the prior art 1 illustrates 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 1 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 price and the quantity of the first-level seller price, which one has a stronger quantity.

Furthermore, the prior art presents the total cumulative volume of each of the five best levels 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 a false impression 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), thereby raising or lowering the stock price. From the best five information of the previous technique one, it is impossible to see whether there is a fake order, nor can it be seen that the fake order has changed.

Due to the limitations of previous technologies, users (investors) cannot see the volume changes of the best five levels or the ratio of large orders to small orders on the screen through a visual line chart. In other words, the technical purpose of the previous technology is not about the visualization 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 technology with the resources of hardware and software to make the best five-level volume visualization technology. When users view the best five levels of a certain stock on the screen, they can quickly identify the information they want to know through the best five-level volume line chart (for example: the proportion of large and small orders in each level, the change of pending orders of false orders, the comparison of different levels of volume, the increase and decrease of each level... etc.), to help users make investment decisions, so as to make up for the shortcomings of previous technologies.

In view of this, the present invention proposes a device and method for visualizing the best five-level volume. In the best five-level view, a corresponding volume line chart is drawn next to each entrustment price. The volume line chart draws the quantity of each entrustment order into a line segment and marks it according to the quotation message sent by the exchange, and the drawn line segments are arranged in chronological order.

Referring to FIG. 1 and FIG. 2, the system functional block diagram of the device 10 for visualizing the best five-level energy and the system functional 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 the best five-level energy of the present invention. In an embodiment of the present invention, the device 10 for visualizing 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 the multiple program instructions contained in the application 20, and implements the following modules in a hardware and software collaborative operation: login verification module 22, best five-level quotation module 24 and data visualization module 26; the screen 16 is used to display the graphical user interface (GUI) of the application 20, and in some embodiments, it 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 network (such as 3G, 4G, 5G, etc.), etc.

Continuing to refer to Figure 2, the system function block diagram of the application program 20 of an embodiment of the present invention includes: a login verification module 22, a best five-level quotation module 24 and a data visualization module 26. 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, such as: international financial quotation module, optional quotation module, detailed quotation module, individual stock news module, accounting module... etc.

The login verification module 22 is used to establish a connection with the server and perform login verification. In some embodiments, after successful login verification, a token is downloaded and stored in the memory 14. 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 (Figures 4 and 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, a 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 volume line chart corresponding to each order price in the best five-level quote message according to the financial product and displays it in the best five-level view 30a, 30b. For example, there are five buy orders and five sell orders in the best five-level quote message, so there are a total of ten corresponding volume line charts 32 (Figure 3, Figure 4). The volume line chart 32 is composed of a plurality of horizontal (i.e., horizontal) line segments in a time sequence, and each line segment represents an order. That is, the volume 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. The length of the line segment is generated in proportion to the order quantity of the corresponding order, that is, the length of the line segment and the order quantity have a fixed ratio, and the longer the line segment, the larger the number of the corresponding order. In some embodiments, the ratio between the length of the line segment and the order quantity is determined according to the width of the display range of the screen 16. For example, the application 20 used in a smart phone needs to determine the ratio of the line segment length to the number of orders according to the width of the mobile phone screen 16. In some embodiments, the ratio between the line segment length and the number of orders is determined according to the largest number of orders in all the volume line charts 32 in the best five-level views 30a and 30b. For example, two different financial products A and financial products 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 views 30a and 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 views 30a and 30b of "financial product B" is 499, the present invention uses different ratios for the line segment lengths of the two financial products. For another example: in all the volume charts 32 in the best five-level views 30a and 30b of the same "financial product A", the maximum number of orders in the previous period is 100, and the maximum 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 length to the number of orders according to the situation. The line segments in a volume chart 32 are separated by separators 40 (as shown in Figure 9). For example: a short straight line segment (i.e., vertical), a symbol, a text, etc. are used as separators. 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 the longest will be executed faster than other orders in the same volume chart), and the other end (end) is the last 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 of 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 newly added order, that is, a separator is generated at the end of the corresponding volume line chart 32, and then a line segment representing the newly added 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 space 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 is not found, the line segment corresponding to the order quantity in the order price that is greater than and close to the reduction 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 quantity 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 quantity 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 quote 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 quote message according to the best five quote messages, 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 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 with a number at the position of the corresponding line segment, as shown in FIG. 10. For example, if the order quantity of a certain order is 96, then "96" is marked at the corresponding position of the corresponding line segment (e.g., above or below the line segment). In some embodiments, the data visualization module 26 further includes: when the line segment has enough length to accommodate the marking of the corresponding order quantity, marking the corresponding order quantity at the corresponding position. That is, the present embodiment needs to determine the length of the line segment, the font size of the annotation quantity, the length of the annotation quantity (such as 2 digits or 3 digits), etc., to determine the length of the line segment that has enough space before the annotation is performed. In some embodiments, the data visualization module 26 further includes: annotating the corresponding increase (including a "plus sign" and a number) or deletion (including a "minus sign" and a number) in the "updated quotation message" at the position corresponding to each volume line chart, as shown in Figure 10. For example: if the order quantity of the second bid price is increased by 21, then "+21" is annotated on the outer side of the end of the volume line chart corresponding to the first bid price. If the order quantity of the first bid price is reduced by 5, then "-5" is marked on the outer side of the end of the volume line chart corresponding to the first bid price. In some embodiments, the data visualization module 26 further includes: marking the line segment with a special visual effect 38 to represent the special order, as shown in Figure 9. The special visual effect 38 is selected from: displaying symbols or numbers or text on the line segment, line segments of different colors (such as: red, blue, green... etc.) and line segments of different styles (such as: thick line, thin line, dotted line... etc.). In some embodiments, the special order is selected from: the corresponding order quantity is greater than the top N% of the order quantities in the past few days in descending order (N is a system-defined value, such as: 5, 10, 20... etc. For example: all order quantities in 3 days are sorted in descending order, and are greater than the top 10% of the order quantities in 3 days), the top N order quantities today (N is a system-defined value, such as: 1, 2, 3. .. etc.), frequently deleted orders (i.e., a specific number of orders that are frequently deleted within a period of time is very likely to be a fake order used to make the market and create a false impression of trading enthusiasm, for example: the order number with the highest order deletion frequency within the same day, 3 days or 5 days) and user-defined order number (for example: using a customized order number of "100", an order number greater than or equal to 100 is a special order). In some embodiments, the data visualization module 26 further includes: receiving an operation instruction of a line segment representing a special order to display corresponding detailed information. The operation instruction is selected from: single click, double click, long press, left mouse click, right mouse click, mouse move, and mouse hover. For example, when a user clicks on a line segment representing a special order (i.e., an operation command to generate a line segment), a pop-up window will be displayed showing detailed information of the special order (e.g., "The quantity of this order has been frequently deleted today, and it is very likely to be a fake order"). 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 buying and selling categories of the corresponding orders, as shown in FIG. 4. The present invention further, in some embodiments, the data visualization module 26 further includes: receiving an arrangement display switching instruction (generated when the arrangement display option button 28 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, 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" 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 36 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 5.

The above-mentioned login verification server, quotation server and transaction server are the same server or the same server cluster in some embodiments; in some embodiments, the login verification server, quotation server and transaction server are different servers or server clusters set up separately; in some embodiments, the login verification server and the quotation server are the same server or the same server cluster, and the transaction server is a different server or server cluster set up separately; in some embodiments, the login verification server and the transaction server are the same server or the same server cluster, and the quotation server is a different server or server cluster set up separately; in some embodiments, the login verification server is an independent server or server cluster, and the quotation server and the transaction server are the same server or server cluster. In the above-mentioned embodiment, after the login verification is successful, a token is downloaded and stored in the memory 14. The purpose of the token is to simplify the login verification process. In some of the above-mentioned embodiments, the login verification server, the quotation server and the transaction server are separately set up servers. When the user successfully logs in to the login verification server with the application 20, if he connects to another server (quotation or transaction), he can avoid the step of manually logging in again. That is, the present invention uses a single sign-on technology to allow users to arbitrarily use the services provided by different servers.

Referring to Figure 3, a schematic diagram of a screen 16 of a computer version of the best five-level volume line chart 32 of an embodiment of the present invention illustrates a graphical user interface of an embodiment application 20 displayed on the screen 16 of the present invention. 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 example is that a personal computer (the best five-level volume visualization 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 based on the best five-level quote message of a single financial product (the example is "TSMC"), and then the data visualization module 26 generates a respective volume line chart 32 corresponding to each entrustment price in the quote message based on 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 to generate and add a volume line chart 32 corresponding to each entrustment price in the best five-level view 30a.

Refer to Figure 4, which is an enlarged schematic diagram of the horizontal best five-level energy-volume line graph 32 of the embodiment of the present invention. The figure illustrates that the present invention adds an arrangement display option button 28 in the best five-level view 30a (clicking it will generate an arrangement display switching instruction) for the user to select the arrangement display of the energy-volume line graph. The illustration is a horizontal arrangement, that is, the buy volume line chart 34 and the sell volume line chart 36 are arranged symmetrically on the left and right. In this horizontal arrangement, the data update directionality of the buy volume line chart 34 and the sell volume line chart 36 is mirror symmetrical, that is, the front ends of the buy volume line chart 36 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. The rounded dashed frame in the legend is only used to explain what the buy side volume line chart 34 and the sell side volume line chart 36 refer to. The dashed frame will not be displayed on the screen 16 when the application 20 is actually operated.

Refer to Figure 5, which is an enlarged schematic diagram of the vertical best five-level volume line chart of an embodiment of the present invention. This embodiment is arranged vertically, that is, the seller's volume line chart 36 and the buyer's volume line chart 34 are arranged symmetrically from top to bottom. 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 direction 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. This embodiment is suitable for use in smart phones or other mobile devices with a slightly smaller screen 16 or a vertical screen display.

Refer to Figure 6, which is a schematic diagram of the screen 16 of the vertical best five-level volume energy line chart for mobile phones in the embodiment of the present invention. The diagram of this embodiment is illustrated by taking the screen style of a smart phone as an example. The arrangement and display of the best five-level view 30b in the example is the same as that in Figure 5, which illustrates that mobile devices with slightly smaller screens 16 are suitable for selecting this arrangement and display.

Refer to Figure 7, which is a schematic diagram of the screen 16 of the mobile phone version of the embodiment of the present invention, which shows that the arrangement of the best five-level view 30b of the present embodiment only has the buy-side volume line chart 34. This arrangement display is also suitable for mobile devices with a slightly smaller screen 16.

Refer to Figure 8, a schematic diagram of the screen 16 of the mobile phone version of the embodiment of the present invention, which shows that the arrangement display of the best five-level view 30b of this embodiment only has the sell-side volume line chart 36, and the arrangement order of the sell-side volume line chart 36 in this embodiment is different from the sell-side volume line chart 36 in Figure 6. The arrangement order of the volume line chart 32 from top to bottom in this embodiment is: first-level sell order, second-level sell order, third-level sell order, fourth-level sell order, and fifth-level sell order, which is exactly the opposite of the order in Figure 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 example is a volume chart 32 of the second-tier buy order (order price "480.0"), which illustrates that the increase "+21" is marked on the outside of the end of the volume chart 32, indicating that the number of orders for the second-tier buy order in the latest best five-tier quotation message has increased by 21. The separator 40 is used to distinguish different orders between the line segments. The separator 40 in the example is a straight short line segment. When there are dense short lines somewhere in the volume chart 32, it means that there are many small orders there, that is, the orders of retail investors are the majority. In addition, the legend marks the numbers representing the number of orders above the line segments in the volume line chart 32 . In some embodiments, when the line segment is long enough to accommodate the corresponding number of orders, the corresponding number of orders is marked at the corresponding position. The legend marks the line segment "the number of orders is greater than 20" with numbers. Furthermore, in some embodiments, the data visualization module 26 marks a line segment with a special visual effect 38 to represent a special order. The volume line chart 32 in the example has two line segments marked with special visual effects 38. The rightmost one is marked with a gray dashed line. It is assumed that the special visual effect 38 of the gray dashed line represents that this special order is a "fake order" (i.e., a specific quantity with frequent order deletions on the same day). The other line segment marked with a special visual effect 38 is a thick black line, and "71" representing the order quantity is marked above it. It is assumed that the special visual effect 38 of the thick black line represents that this special order is "the top five order quantities today".

Referring to FIG. 10 , a diagram of the screen 16 of the mobile phone version of the buyer volume line chart 34 and the order quantity mark of the embodiment of the present invention, the present embodiment adds order quantity marks to the line segments of some orders in FIG. 7 (the example adds marks to the line segments where the order quantity is greater than 20), and adds marks of increase 42 and decrease 44 to the volume line chart 32. The legend shows that in the updated quote message, the order quantity of the first buy order (order price "480.5") decreased by 5, the order quantity of the second buy order (order price "480.0") increased by 21, and the order quantity of the fourth buy order (order price "479.0") decreased by 2. From the legend, users can easily identify the proportion of large orders and small orders in each level of volume chart 32, the change of pending orders of false orders (for example, a certain order originally in the first level of selling orders is deleted before it is about to be executed, and then another order of the same quantity is added to the second level of selling orders), the comparison of different levels of volume (for example, when arranged vertically, it is easy to compare the length of the volume chart 32 of the first level of buying orders and the first level of selling orders, as well as the proportion of large orders and small orders in the two), the increase 42 and decrease 44 of the volume chart 32 of each level, etc.

Refer to Figure 11, which is a schematic diagram of the screen 16 of the vertical best five levels (also known as "five-level market") 30b of the present invention applied to mainland stocks. The figure 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 Figure 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.

Refer to Figure 12, an operation flow chart of an application 20 of an embodiment of the present invention, the user uses a device (such as a personal computer/smart TV/smart phone/tablet computer/stock machine) to execute the application 20 and then switch to the operation flow of the best five-level view 30a, 30b of a certain financial product. Please refer to Figures 1, 2, 3 and 6 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 energy visualization.

Step S102: Establish a connection with the server and perform login verification. After the communication module 18 establishes an Internet network 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, when 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 biometrics, 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 (quotation server) and stores it in the memory 14, and then generates the best five-level view 30a by the best five-level quote module 24. 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 a volume line chart 32 corresponding to the order price according to the quote message and display it in the best five-level view 30a, 30b. After downloading the best five-level quote message in the previous step, 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, 30b. The computer version is shown in Figure 3, and the mobile version is shown in Figure 6. The volume line chart 32 is composed of a plurality of line segments in a time sequence. Each line segment represents an order, and the length of the line segment is generated in proportion to the order quantity of the corresponding order. One best five-level quote message contains one to multiple order prices (one order price is equal to one order), that is, one best five-level quote message draws one to multiple corresponding line segments of the volume line chart 32. For example, one best five-level quote message contains three order prices and corresponding order quantities, that is, the data visualization module 26 draws a new horizontal line segment on each of the three corresponding volume line charts 32. In some embodiments, each order in the quote message carries its own order sequence number (that is, each order price has its own order sequence number), and each line segment drawn in this step carries the corresponding order sequence number, that is, the corresponding line segment can be searched for using a specific order sequence number. In some embodiments, each order in the quotation message does not have its own order sequence number, and the line segment drawn in this step does not store the order sequence number.

Step S105: Draw, delete or shrink line segments on the corresponding volume energy line chart 32 according to the updated best five-level quote message. In the trading session (i.e., during trading hours) and when the screen 16 displays the best five-level views 30a, 30b, the best five-level quote module 24 continuously downloads the quote message of the financial product from the quote server and continuously updates the best five-level views 30a, 30b, and the data visualization module 26 draws, deletes or shrinks line segments on the corresponding volume energy line chart 32 according to the updated quote message. In step S103, if each order in the quotation message of the embodiment carries its own order number (i.e., each order price has its own order number), each line segment drawn in step S104 will carry the corresponding order number. In this step S105, when an order is to be deleted or the order quantity is to be reduced, the corresponding specific line segment can be found according to the order number to be deleted or reduced. This type of embodiment accurately presents data visualization. In step S103, if each order in the quotation message of the embodiment does not have its own order serial number, the line segment drawn in step 5104 will not have a corresponding order serial number. In this step S105, when an order is to be deleted or the order quantity is to be reduced, it is deleted or reduced by estimation. For orders with smaller order quantities, there may be a slight difference when deleting or reducing them, but it does not affect the observation of orders with larger order quantities. For example: Assume that a best five-level quote message contains the order quantity (cumulative quantity) of the first-level buy order (order price "480.5") and the second-level buy order (order price "480.0"), and it is necessary to compare it with the "previous quote message" to calculate the increase or decrease in this quote message. Assume that after calculation, the order quantity of the first buy order (order price "480.5") increases by 21, and the order quantity of the second buy order (order price "480.0") decreases by 199. The data visualization module 26 adds a separator 40 and a new horizontal line segment (the length of the line segment is a ratio corresponding to "21") at the end of the volume line chart 32 of the first buy order. In the embodiment with order sequence numbers, the newly added line segment will record the corresponding order sequence number, so that when the order is to be deleted or the order quantity is to be reduced, the corresponding order sequence number can be used to directly find the correct line segment to delete or reduce the length. In addition, continuing the previous example, in the implementation without order numbers, if you want to delete 199 orders, search for the order with the previous order quantity of "199" in the second-tier buy volume line chart 32. If an order that matches the quantity is found, delete the corresponding line segment. If an order that matches the quantity "199" is not found, search for the most recent order with a quantity "greater than 199" and shorten the length of the corresponding line segment to the corresponding proportion. If in the implementation with order numbers, if you want to delete the order quantity of 199, just look for the line segment corresponding to the order number based on the order number, and then delete or reduce it.
