Problems solved by technology

However, for the securities service industry that needs to transmit a large amount of data to its many customers in the form of wireless communication, these uncompressed data will consume a large amount of its precious and limited wireless communication bandwidth, and cause its service efficiency and The quality is reduced and needs to be further improved

Abstract

The invention relates to a data processing method, comprising analyzing a plurality of fields of at least one data block, to respectively calculate out the distribution of the values of each field of each data block; according to the distribution, determining the group and coding method of the field and combining the group and coding methods of all fields into a coding rule; according to the coding rule, coding other data. The coding rule can effectively reduce data amount and comprises that: according to the codes of the data to group and code the data, thereby reducing the value of the transmission serial number; the price of the data is represented by a relative price; representing the data having business completion record in one minute via relative time difference value; according to the amount of each data block, representing the data via a suitable field width and coding method.

Description

technical field [0001] The present invention relates to a data processing method, in particular to a data processing method for encoding the characteristics of securities transaction data such as stocks, futures or options to reduce the amount of data. Background technique [0002] At present, most of the transaction data of securities such as stocks, futures, or options are provided by management institutions of securities, such as stock exchanges and the like. These securities data can be real-time data obtained from the management agency through a dedicated network during daily intraday trading, or downloaded from the management agency to obtain historical data or statistical data at any time. Traditionally, data provided by this governing body is transmitted in an uncompressed, standardized code. The data length of each field contained in each piece of data must be sufficient to contain the maximum possible value. Therefore, this existing uncompressed encoding method w...
