The Financial Information eXchange (FIX) Protocol is a series of messaging specifications. It is a global language describing trade-related messages, and is used for automated trading of securities, derivative, and other financial instruments. For more information on the FIX protocol, see the FIX protocol Web site.
FIX messages can be modeled using the MRM Tagged/Delimited String Format (TDS).
A predefined message set solution for FIX can be purchased from IBM. See the WebSphere MQ SupportPacs Web page.
