FIX Session Layer

 

This page features FIX Protocol Session Layer specifications and presentations.
With the release of FIX Protocol Version 5.0 the session layer specification was separated from the application layer specification (aka Transport Independence).  "FIXT" is the label used to identify the separate session layer specification and to identify the FIX Session version being used.
