Upcoming AIX Trading Platform Upgrade to 4th Generation on January 3, 2026 – Notice 1
This significant upgrade includes the launch of two new trade and market data distribution channels: new gateway for FIX 5.0 SP2 and a new gateway for the ITCH protocol.
- Testing: A test environment for these new protocols is already available, starting September 29, 2025.
- Training: In November 2025, AIX will host a series of training sessions focusing on the benefits of the new FIX 5.0 SP2 and ITCH protocols.
Action for Existing Users: Participants currently using the AIX MCT FIX Proxy (FIX version 5.0 SP1 and below) are not expected to require changes. However, any potential updates to the AIX MCT FIX Proxy will have their specifications available by November 26, 2025, and will require mandatory retesting by Trading members starting from the date of announcement.
We will continue to provide updates throughout the upgrade phase.
