Embodiment Construction

[0036] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0037] The present invention provides a method for data transmission of stock quotations. The data sender classifies the data fields of the quotation data provided by the data provider according to the size of the data field value bytes to form a coding list, and encodes the data fields. And send the encoded data to the data receiver; the data receiver uses the same classification encoding method and encoding list as the data sender to decode the received data. Among them, the data provider refers to information providers such as exchanges; the data sender refers to the market data processing center, and all the data provided by the data provider are processed and processed in a unified format at the data sender; the data receiver refers to the final data of the unified format. Use units.

Abstract

The present invention discloses a method for transmitting the data of the stock quotation. A data provider provides the quotation information to a data transmitter with a form of data field. The invention is characterized in that the method comprises the following procedures: decoding the received quotation data by the data transmitter according to a data format defied by the data provider; extracting a data field from the decoded quotation data by the data transmitter, sorting the data field according to the magnitude of the byte of the data field value to form an encoding list, and executing code number sorting to the data field; transmitting the coded data to the data receiver by the data transmitter; and decoding the received data with a data field sorting coding mode and a coding list which are same to the data transmitter by the data receiver. The invention also discloses a coding system of the stock quotation data. The invention increases the adaptability to the variation of the data format of the quotation data and increases the speed of the data updating of the user terminal.

Description

technical field [0001] The invention designs a data transmission technology, in particular a method and a system for transmitting securities market data. Background technique [0002] In the securities industry, market data is the basis of the data analysis system. Changes in the quotation information of each security reflect changes in the market and directly affect the investment behavior of investors. Therefore, the securities industry is constantly pursuing faster market data update speed . [0003] With the maturity of the securities market, the market data provided by various stock exchanges is more abundant, and the amount of data has also increased a lot. Usually, the stock exchange provides market data in the form of data fields, and one of the data fields includes at least the name of the market data category and the value of the market data category. The name of the market data category is the name of the data field, such as: opening price, closing price; the va...
