Description

Device and method for stock selection analysis based on brokerage points

The present invention relates to a stock selection analysis technology for investment stocks, and in particular to a device and method for stock selection analysis based on brokerage points.

Stock investors need to open an account at a certain branch (i.e., branch) of a securities company before they can start buying and selling stocks. All stock trading information at each branch of the securities company will be collected by the Taiwan Stock Exchange on each transaction. Announced in the evening of the day, this is the brokerage point information. Investors can use the brokerage point data to find out how many shares of a certain stock were traded (bought or sold) at what time, at which brokerage point, and at what price. For example: Tuyin-Nangang bought 138 shares of TSMC for 424 yuan on August 14, 2020, as shown in Figure 1. Figure 1 is a schematic diagram of the previous technology showing the web version of the brokerage point information (data source: Taiwan stock exchange).

Currently, regardless of whether it is a prior technology running on a personal computer or a mobile device (for example, stock quotation software or stock trading software), brokerage point data are used to analyze the chip status of a single stock, and the user (i.e., When investors) operate the previous technology, they first lock in a specific stock and then check the brokerage point information. For example: the user clicks TSMC in the "optional stocks" of the previous technology, and then selects TSMC from In the menu of the previous technology, click "Chips" and then click "Broker Branches", and then you can learn from the downloaded data that "the brokerage branch that TSMC has bought the most in recent days is Thubank-Nangang." The chip data query method provided by the previous technology only allows users to query in a one-way manner (from individual stocks to brokerage points), and users cannot query data from more comprehensive and different perspectives. For example, users cannot compare the queried data horizontally (i.e., the same type of industry at the same branch) with the sales of other commodities, let alone other industries at the same branch.

In addition, when users use the previous technology to check the brokerage point data of a specific stock, they can only know the trading status of the specific stock at each point within a specific range, or click on a specific point to query the specific point. Users cannot query other information about the specific stock trading status of this specific point.
