OKCoin provides FIX API to enable user fast data access and trading through real time connection. The Financial Information eXchange(FIX) Protocol is a series of messaging specifications for the electronic communication of financial data, including trade-related massages. It is a globally accepted standard of messaging specifications developed through the collaboration of banks, brokers, exchanges, institutional investors and information technology providers from around the world.
OKCoin supports a minimal subset of the FIX protocol version 4.4. All tags required by FIX 4.4 are required by OKCoin. Optional tags are not required (and are often left out) in order to create the lowest common denominator in terms of functionality. However, a few optional tags have been made mandatory in order to facilitate better information flow. If an optional tag does not appear in a message definition, it is safe to assume that it is ignored by OKCoin. A list of custom tags and message specific can be found in http://www.onixs.biz/fix-dictionary/4.4/index.html
Furthermore, if user has any previous development experience of financial nature, the FIX API can also apply.
