Description

Apparatus and method for displaying best-in-class order mark

The present invention relates to a technology for placing orders on stocks, and more particularly, to a device and method for displaying the order mark of the best five levels.

The best five-level bid-ask price (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 traded, and the price and number of the lowest five-level sell orders that have not been traded. This information can help Investors make investment decision references, determine the price of buying or selling individual stocks, and can know whether the entrusted trading is completed at the best price.

A stock order (hereinafter referred to as an order) refers to a securities dealer accepting an order from a stock investor (client) to buy or sell stocks. Generally, the order contains at least the information of the order, the time of the order, Stock name / symbol, quantity, price, duration of mandate, buy / sell.

At present, mobile device financial ordering software adopts a separate processing method for the best five-level buying and selling orders. For example, the first prior art, Republic of China Patent Bulletin No. I499993, discloses a "device and method for integrating order placing and best candidate grade view software for mobile device financial ordering software". The method includes the following steps: executing financial ordering software; Select order and best candidate Grade integration view option to display the order and best candidate grade integration view. The order and best candidate grade integration view is combined and integrated by the following single view and a best candidate grade view. The order view contains A product code input box and a price input box, and the best candidate grade view is generated based on the best candidate grade information; enter a product code information into the product code input box; operate scrolling / sliding to place an order and the best candidate Grade integrated view; enter a grade price; enter a quantity; and, confirm the order. The first technology disclosed the method of integrating the best five screens and generating orders for mobile device financial ordering software.

The second prior art, Republic of China Patent Bulletin No. I435284, discloses a "high and low price marking device and method for mobile equipment financial products", which includes the following steps: executing a software for viewing the disk; operating a menu of the software for selecting the disk for selecting A best five-grade function. The best five-grade function displays a best five-grade screen, which includes a plurality of the best five-grade price information of a financial commodity. The financial commodity includes a highest price information and a lowest price information. Information; when the price and volume information of the best five files includes the highest price information and the lowest price information, a highest price mark and a lowest price mark are respectively included in the highest price information and the lowest price information. And the lowest price indicator is placed outside the box or column beside the best five file containing the highest price information and the best five file containing the lowest price information, respectively. Inside the box. The previous technology 2 revealed how the mobile device financial order software generates the best five files and the high and low price marking of the financial product.

Due to the limitation of the previous technology, after the user (investor) placed the order, if he looked back at the best five levels of information using the previous technology, he could not know the relationship between the order and any price in the best five levels of information. (I.e. which of the best five is the order price? Times), and the relationship between the number of orders and the number of orders of the same price grade cannot be known in the best five grades of information. Especially when the user places multiple orders at the same time, or pays attention to multiple stocks at the same time but forgets which orders have been placed, what the order price is, what the quantity is, etc. Under this circumstance, the above-mentioned prior art cannot meet the user's needs, so the user must switch to the order query view to see which orders have been sent, what the order price is, and what the order quantity is. However, in order to understand the relationship between the current best five grades and the order price (for example: whether the order price is within the best five grades, and how many orders are the best five grades), or Yes, in order to understand the relationship between the number of orders and the number of best-ranked fifth-level commissions, the user must switch back to the view of the best fifth-rank. The first technique is to provide the best candidate grade (best five grades) information in the order view when the user places the order. Therefore, the first technique cannot solve the above problem. As for the prior art two, displaying the highest price mark and the lowest price mark in the best five files cannot solve the above problems. In other words, the technical objectives of the previous technologies 1 and 2 are to solve the problem of presenting the best fifth-grade and other information of financial commodities in real time, not the user's transaction information problem.

That is to say, the prior art cannot meet the needs of the user to display the information in the top five files and the order information they have placed. Therefore, it is really necessary to improve the method of the previous technology, and propose a technology that uses the best five files to display the order mark with resources that work in conjunction with hardware and software, so that when users view the best five files of a stock, they can At the same time, check whether the order price is within the best five levels in order to make up for the lack of previous technology.

In view of this, the present invention proposes a device and method for displaying the order mark of the best five levels. After the user places the order, if the price of the order is within the best five levels, the best The mark representing the order is displayed in the fifth-level view, so that the user can see the relationship between the best fifth-level and the order price at a glance.

The present invention proposes a device with the best five-level display order mark. The device includes: a communication module for establishing an Internet network connection; and a login authentication module for establishing a connection with a server and performing Login verification; a best five-level module for downloading one of the best five-level information of a financial product, and generating one of the best five-level view of the financial product based on the best five-level information; a transaction module, using To generate an order, upload the order to a transaction server; an order marking module, download the order information corresponding to one of the financial commodities, generate an order mark based on the order information, and check The best five-level information of the best five-level view and displaying the order mark at a position corresponding to an order price; a memory for storing an application and the order information, the application including the login verification Module, the best five-level module, the transaction module and the order marking module; a screen to display the graphical user interface of the application; one or more processors connected to the memory The screen and execute the application.

The invention still further, in some embodiments, the order marking module includes: receiving an opening instruction of one of the order markings to switch to an order view, the order view showing the order corresponding to the order marking .

The invention also proposes a method for displaying the best five-level display order mark, which is applied to a device. The device includes a communication module, a memory, and a screen.

Referring to FIG. 1 and FIG. 2, the system function block diagram of the device 5 and the application program 20 of the best five-level display of the order mark of the present invention are shown in the figure, and the legend is only related to a preferred embodiment of the present invention Core modules, the remaining modules are omitted and not depicted. The application program 20 is executed on the device 5 for displaying the order mark of the best five levels of the present invention. In an embodiment of the present invention, the device 5 for displaying the order mark of the best five levels of the present invention includes: one or more processors 12, a memory 14, a screen 16, and a communication module 18. Among them, the memory 14 stores an application program 20; the processor 12 executes a plurality of program instructions contained in the application program 20, and implements the following modules in a cooperative manner of hardware and software: the login authentication module 22, the best five File module 24, transaction module 26, and order mark module 28; screen 16 is used to display the graphical user interface (GUI) of application program 20; 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 ...), etc.

Continuing to refer to FIG. 2, a block diagram of a system function of the application program 20 according to the embodiment of the present invention includes: a login authentication module 22, a best five-level module 24, a transaction module 26, and an order mark module 28. Only the core modules related to a preferred embodiment of the present invention are listed, and the remaining modules are omitted and not depicted.

The login verification module 22 is used to establish a connection with the server and perform login verification. In some embodiments, after the login verification is successful, a token is downloaded and stored in the memory 14. The login verification includes multiple methods. In some implementations, In this example, the account and password are used for authentication; In some embodiments, the user's biometrics are used for identity verification, such as fingerprint identification or Face ID identification.

The best five-level module 24 is used to download the best five-level information of stocks or other financial commodities from the quotation server, and then generate the best five-level view according to the downloaded best five-level information.

The transaction module 26 is used to generate an order and upload the order to a transaction server. The order generation method is the transaction view (belonging to the conventional technology, not depicted) generated by the trading module 26 to receive the user-entered entrustment conditions, such as: product name or code, quantity, price, order validity period, buy / sell ... and so on. The user finally presses the "confirm button" (not shown) to generate an order, and each order has a unique set of order numbers. Then, the transaction module 26 uploads the order to the transaction server.

The above-mentioned login authentication server, quotation server and transaction server are, in some embodiments, the same server or the same server cluster; in some embodiments, the login authentication server, the quotation server, and the transaction server are Different servers or server clusters separately set; in some embodiments, the login authentication server and the quote server are the same server or the same server cluster, and the transaction server is a different server or server separately set Cluster; in some embodiments, the login authentication 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 that is separately set; in some embodiments, the login The verification server is an independent server or server cluster, and both the quotation server and the transaction server are the same server or server cluster. In the foregoing embodiment, a token is downloaded and stored in the memory 14 after successful login verification. The purpose of the token is to simplify the login verification process. In some of the above embodiments, the login authentication server, the quotation server and the transaction server are separate The server is set up. After the user successfully logs in to the authentication server using the application 20, if he connects to another server (quote or transaction), the step of manually logging in again can be eliminated. That is, the present invention uses a Single Sign-On technology to allow a user to arbitrarily use services provided between different servers.

The order mark module 28 downloads the order information of the corresponding financial product from the transaction server, generates the order mark according to the downloaded order information, and checks and filters the best five-level information in the best five-level view and correspondingly The order mark shows the position of the order price. The so-called corresponding financial products are the financial products selected by the user. For example, when the user chooses to switch to the best five-level view of "TSMC", the selected financial product ("TSMC") is the corresponding financial product. ". In some embodiments of the present invention, the order marking module 28 can download the order information (ie, all order information) of "corresponding to all financial commodities in the user account" at one time, which means that the user who logged in at that time All "unfilled active orders" in the account. For example: the user has placed "4 orders" on the same day, including "TSMC Buy Order", "Dali Legislative Commission Buy Order", "Hon Hai Commission Sell Order", and "Acer Commission Buy Order", among which, "Acer Commission Buy Order" Has been transacted, the remaining 3 transactions are still valid. Therefore, all the order information downloaded by the order labeling module 28 are the "TSMC Buy Order", "Dali Optical Commission Buy Order" and "Hon Hai Commission Sell Order", which are three valid orders that have not been transacted. 28 In a later step (for example, when switching to the best five-level view of a financial product), the corresponding corresponding financial product is filtered out from it. The so-called order mark is the display mark corresponding to the order. The mark can be a symbol, picture or text type, or any combination of two or more of them. This order mark is displayed in the view of the best five levels, so that the user can easily identify whether there are orders in the best five levels. In some embodiments, the tags generated by the order tag module 28 also include Number type, the number is used to indicate "the number of outstanding orders". As for "checking and filtering", when the user switches to the best five-level view of a financial product, the order mark module 28 checks and filters whether the current best-five price of the financial product covers the commission. Single price. If the price of the order after checking and filtering is equal to the price of a certain grade within the best five grades, the order marking module 28 sets an order mark at a position corresponding to the grade. For example: "The purchase price of TSMC's commission is 200 yuan", and the current "the first purchase price of TSMC's top five is also 200 yuan", the order mark setting is displayed at the position corresponding to the first purchaser. The so-called "corresponding" first-stage buyer position may be "first-stage buyer price", or "first-stage buyer number". In some embodiments, the order mark module 28 generates a dynamic calculation of the number of unfilled orders, and updates and displays the number of unfilled orders on the order mark after the change. For example: Originally, "the number of TSMC purchase orders was 3 stocks" (that is, "3000" shares), and the order displayed by the order mark module 28 in the best five-level view is labeled "Commit 3". When only one "one stock" is transacted in the order, the remaining number of orders is "two stocks". Therefore, after the calculation, the order mark module 28 updates and displays the order mark as "Committee 2". This embodiment allows the user to easily identify the remaining number of unsettled orders from the best fifth gear, so that the user can easily see the relationship between the number of orders and the number of times of the best fifth gear. For example, the number of orders is much larger than the number of orders, which means that the order cannot digest all the orders at once.

The invention further goes on, in some embodiments, the order marking module 28 includes: receiving an opening instruction of the order marking to switch to the order view to display the order corresponding to the order marking. In this embodiment, the order mark is set as a button for opening the order in advance, and an opening instruction is generated when the user presses the order mark. When the user needs to change the order, for example For example, the original order mark is displayed in the fourth level of the best five levels. If the user wants to move to the first level to complete the transaction as soon as possible, he can directly click the order mark (that is, an open instruction is generated). After the order mark module 28 receives the opening instruction of the order mark, it will switch from the trading module 26 to the order view and display the order corresponding to the order mark, so that the user can change the original order price. The invention allows the user to quickly switch to the order in the best five-level view to change the price, quantity, or delete the order.

Referring to FIG. 3, a schematic diagram of the screen 16 of the best fifth-level view 30 and the order mark 32 according to the first embodiment of the present invention illustrates the graphical use of the application program 20 displayed on the screen 16 according to a preferred embodiment of the present invention.

In this embodiment, the smart phone (the best five-level display order marking device 10) displays the best five-level view 30, and the legend illustrates that the best five-level module 24 is based on a single financial commodity (the illustration is "TSMC") After generating the best five-level view 30 of the best five-level information, the order mark module 28 generates the order mark 32 according to the order information for downloading the corresponding financial product, and displays it at the position corresponding to the order price. Assume that "the purchase price of TSMC's order is 200 yuan", so "the position corresponding to the order price" is the first level of the buyer with the best five levels of information. The display position of the order mark 32 in the illustration is the first-grade price of the buyer, and the order mark 32 in this embodiment is represented by a combination of a symbol (small bracket) and a word ("committee"). The order mark 32 of the present invention allows the user to know at a glance whether the order price is within the current best five levels and at what level. This information can help users decide whether to change the order price to adjust The grade. In addition, the present invention also eliminates the need for user operation The learning technique requires the complicated operation steps of switching back and forth in the best five-level view and the order query view, and comparing information (the order price and the best five-level price).

Referring to FIG. 4, a schematic diagram of the screen 16 of the best fifth-level view 30 and the order mark 32 in the second embodiment of the present invention. Assuming that “the purchase price of TSMC's order is 200 yuan”, the order mark 32 in this embodiment is displayed. The number of positions at the buyer's first level.

Referring to FIG. 5, a schematic diagram of the screen 16 of the best fifth-level view 30 and the order mark 32 in the third embodiment of the present invention. Assume that “the order price of TSMC order is 200 yuan, and the order amount is 3”. The order mark 32 in the embodiment shows the number of positions in the first grade of the buyer, and the number “3” displayed in the order mark 32 in the illustration represents the quantity ordered. In this embodiment, because the number of orders is directly displayed in the order mark 32, the user can easily recognize the relationship between the number of orders and the number of pending orders of the grade. For example: "the number of orders is less than the number of pending orders of this grade" (ie, the case of the legend), or "the number of orders is greater than the number of pending orders of this grade". This information is helpful to assist investors in deciding whether to change the number of orders, and the order mark 32 of the present invention directly displays the number of orders. It also eliminates the need for users to learn the technology in the best five-level view and order query view. The complicated operation steps of switching back and forth and comparing information (the number of orders and the best five files).

Step S104: Download the order information of the corresponding financial commodity. The order marking module 28 downloads from the server (transaction server) the "unfilled valid order" of all "TSMC" (that is, corresponding financial products) in the account of the logged-in user. This example assumes " TSMC has 1 commission order, with a purchase price of 200 yuan and a quantity of 3 ". In some embodiments, step S104 is performed in synchronization with step S103; in some embodiments, step S104 is performed after completion of step S103. In some embodiments, the order marking module 28 can download the order information of "corresponding to all financial commodities in the user account" at one time, and store it in the memory 14 first, and then filter out the information from step S105 later. Corresponding financial commodities are required (ie, "TSMC" in this example).

Step S105: Generate an order ticket mark 32. After downloading the order information of the corresponding financial commodity, the order mark module 28 generates an order mark 32 based on the "TSMC" order information. Taking the order mark 32 in the third embodiment (as shown in FIG. 5) as an example, it is "small brackets plus text plus numbers" (the text indicates the order, and the number indicates the number of orders), that is, "(Committee 3)" .

Step S106: Check the best five files and display the order mark 32 at the corresponding position. After the generation of the order mark 32, the order mark module 28 checks and filters whether the current best-five bid price of "TSMC" covers the price of the order. If "the price of the order is covered", the order is marked. 32 is displayed at the position corresponding to the order price (the order price in this figure is "buy 200 yuan"), as shown in FIG. 5.

Step S107: Click on the order mark 32. When the user views the order mark 32 in the best fifth-level view 30, in some embodiments, the user can directly click the order mark 32 (generate an open instruction) to switch to the order view. The order mark 32 is set to the button mode here, and it is an open instruction for switching to the order view.

Step S108: Switch to the order view. After the order marking module 28 receives the opening instruction of the order marking 32, it switches from the trading module 26 to the order view (this view is a conventional technology, not depicted) to display the order corresponding to the order marking. Allows users to quickly change the price, quantity, or delete orders.
