For AIX Trading Members

AIX Specifications
Mapping Difference

Notice #4

Dear Trading Members,

The updated testbed for AIX MCT FIX Proxy is available. We kindly request that you test your current connectors to avoid any issues after the AIX trading platform upgrade.

Despite the technical readiness, AIX has decided to postpone the trading platform upgrade due to several requests from members. The new tentative date for go-Live is 20-Feb-2026.

We believe that this delay will ultimately benefit all stakeholders as it gives us all more time to improve our readiness and ensure a smooth transition to the new trading platform.

The steps that you need to perform for the testing are as follows:

  1. Read the updated specifications of MCT FIX Proxy SP1 (attached) paying attention to the GAPs highlighted in red (also will be available at https://aix.kz/for-aix-trading-members)
  2. Write to AIX Market Operations and On-boarding Department to get credentials for the updated Test environment
  3. Provide public IP addresses that will be used for testing the new Web Trader (https://test-webtrader.aix-kz.com) to AIX IT Operation
  4. Get Test scenario from AIX Market Operations and On-boarding Department and perform test cases. During this phase, please feel free to contact AIX IT Analytics for any technical questions.

We recommend testing the current system (test web-Trader and upgraded MCT FIX Proxy) to determine the impact and identify hidden errors and avoid operational downtime.

Upcoming AIX Trading Platform Upgrade to 4th Generation on December 26, 2025 – Notice #2 (22/10/2025)

A test environment for connecting to the new versions of FIX 5.0 SP2 and ITCH has been available since September 29th.
This is for participants modifying their systems to integrate with the new data sending/receiving channels.
These protocols differ from the current format and contain new fields/blocks to support the new functionality.
We recommend switching to implement for the new protocols and beginning the modification process promptly, as support for the current version will be discontinued in the second quarter of 2026.

Starting November 26th, the current (re-developed) MCT FIX 5.0 SP1 protocol will be available for testing, as it is also undergoing revisions and some format changes are possible. We strive to ensure a seamless transition for participants, but due to the significant differences between the formats of the current and new protocol versions, some changes are inevitable.

A list of identified issues is available on the website (https://aix.kz/for-aix-trading-members) and will be updated regularly. Therefore, we ask you to pay attention and thoroughly test the current system to determine the impact and identify hidden errors and avoid operational downtime.”

Upcoming AIX Trading Platform Upgrade to 4th Generation on December 26, 2025 – 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.
