FIX 5.0 vs FIX 5.0 SP2: What Changed

FIX 5.0, 5.0 SP1 and 5.0 SP2 all run over FIXT.1.1, so the session layer does not change. The service packs add messages and a very large number of fields; SP2 also takes in the later extension packs.

BeginString: FIXT.1.1 and FIXT.1.1. Counts come from the standard data dictionaries; FIX 5.0 counts include the FIXT 1.1 session messages and fields.

Migrating from FIX 5.0 to FIX 5.0 SP2

  • Sessions stay on FIXT.1.1. The difference is the application version: DefaultApplVerID (1137) or ApplVerID (1128) = 7 for FIX 5.0 and 9 for FIX 5.0 SP2.
  • SP1 adds market structure messages such as Market Definition, and order mass actions. SP2 adds risk limits, party entitlements, stream assignment and many derivatives fields.
  • SessionRejectReason 373=18 (unsupported application version) and CxlRejReason codes 7 and 8 arrive in SP1.
  • SP2 adds BusinessRejectReason throttle codes 8 to 10, ExecType M and N, and OrdRejReason codes up to 29.
  • Twelve fields are renamed, for example SideQty (1009) becomes SideLastQty and UnitofMeasure (996) becomes UnitOfMeasure.
