Hi, Can I know what is the difference between FIX4.4 and FIX5.0?
Is it just unlock the application layer from session layer?
Seperation of Session and application layers is the biggest difference. There are two thing here:-
Transport Independence - This permits use of non-TCP Sessions
Application version independence - This permits multiple versions of FIX application messages to be carried over a single FIX session
Jim Northey is submitting a proposal to permit firms without the need for application version independence or transport independence to simply use 8=FIX.5.0, 8=FIX.5.0SP1, 8=FIX.5.0SP2, etc. refer http://fixprotocol.org/discuss/read/792b31ea
Also check the release notes / appendix of the specs to see differences between versions. In FIX repository, there is a “TOOLS AND SAMPLES” described as “Compare FIX Messages between versions (Sample Application.zip, 14KB) A simple XSLT that compares the Tags that make up each message in FIX to the Tags that make up the same message in another version. The results are displayed as a basic HTML document”. This XSLT tool is available at
http://fixprotocol.org/documents/874/Sample%20Application.zip
