The TT FIX service allows customers to receive real-time copies of all of their orders submitted through the TT platform, along with their corresponding fills. To use this service, customers must develop FIX clients capable of connecting to and communicating with the TT FIX.
TT FIX supports a subset of the FIX protocol (Version 4.2 with Errata 20010501) message types and tags within the message types. Refer to the website http://www.fixtradingcommunity.org/ for additional FIX tag descriptions and message definitions. If desired, you can download a copy of the TT FIX Data Dictionary, TT-FIX42.xml.
Note: TT FIX supports only those messages and tags described in this document. Do not submit other messages or tags to TT FIX, as doing so can produce unexpected results.
