  • Examples: This is all you need!
  • Tester: A very simple test suite to stress out any Session level implementation.
  • Session: All of the statemachines and message handling for the Fix Session. ie the business logic lives here.
  • Messages: Code generated Fix Messages for all versions of fix.
  • Common: The code generator and common classes - including all the code generated Fields.

What is this project?

SackFix is a Scala session layer fix implememtion. This project includes all of the generated Fix messages for every version of Fix.

They are all immutable, and can be rendered toString as human readable, or to Fix. They also have decoders to hook into the session layer which can turn incoming fix into the correct message.

Please visit for instructions on how to run the example initiator and acceptor.
