Getting connected

From a signed agreement to live production sessions
in four steps, with a conformance test on the way.

Step 01

Sign the agreement

FIX access starts with a signed agreement on Match-Trader use.

Step 02

Configure your engine

Set up your FIX 4.4 engine as the initiator for both sessions.

Step 03

Conformance test

A conformance test is required before production access.

Step 04

Go live

Move your sessions to production once testing is complete.
