Abstract

The invention discloses a market data access method and device. The method comprises the following steps: receiving a market data message pushed by a data source; determining an external code identifier type corresponding to an external code identifier in the market data message according to the external code identifier type corresponding to each external code identifier recorded in the transaction variety receiving configuration table; if the external code identifier in the market data message is a chained code identifier, obtaining a field processing rule corresponding to the chained code identifier from a preset chained code analysis rule table, reading a target field from the market data message according to the field processing rule, and initiating subscription to the data source by taking the target field as a single code. According to the invention, the access of the chain code can be realized, and the efficiency of accessing market data provided by a supplier is improved.

Description

technical field [0001] The present invention relates to the field of financial data processing, in particular to a market data access method and device. Background technique [0002] Currently, market data suppliers release market data in single code (also known as quote code) and chain code. Single code is the smallest unit for market data suppliers to release market data, and each single code corresponds to the most subdivided To quote, a chaincode contains one or more chain subcodes, and each chain subcode contains a plurality of individual codes. The market data access system in the prior art only supports the access of a single code, and does not support the access of chain codes. Because chain code access is not supported, when there are a large number of individual codes under a chain code, only individual quotation codes can be accessed separately, resulting in large access code parameter maintenance work, which is time-consuming and laborious. Contents of the inv...
