For AIX Trading Members

Notice #7

AIX hereby recommends that brokers AND Independent Software Vendors intensify their efforts towards migration readiness as we approach the go-live date whose date will be confirmed shortly.

In particular, regarding:

Brokers using WebTrader. No re-certification will be required since the new OMS is similar in all aspects to the current one. However, we urge all brokers to conduct the self-certification process described in the summary at the end of this communication.
Market-makers. It is expected that Market-makers now plug their MM algo into the new matching engine and start sending quotes as if they were live.
FIX Users (SP1 & SP2). Increased participation is expected from all FIX users. In-house and third-party FIX-based OMS will require re-certification on the new platform. FIX brokers are kindly requested to contact the Market Operations team of AIX via the Jira portal to schedule a certification session.

Dear Trading members,

Kindly review the updated scheme outlining the available options for establishing connectivity to the AIX test servers.

Brokers using Web Trader
If you are using only the Web Trader to submit orders, please access the test Web Trader using the credentials provided by the AIX Market Operations and On-boarding Department
Brokers planning to set up SP1 (modernized)
If you are using SP1 (modernized), please update the test server address to 10.30.253.86 and perform testing of market data availability and order management using your FIX SP1 credentials.
Brokers planning to set up SP2 (FIX and ITCH)
If you are using SP2, where both FIX and ITCH channels are available, please use the respective FIX and ITCH credentials.
Order management and connectivity should be tested via FIX, while market data availability should be tested via ITCH.

All Trading Members are required to complete testing of the Web Trader, FIX and ITCH, or SP1(modernized) by 20 February 2026.

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:

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)
Write to AIX Market Operations and On-boarding Department to get credentials for the updated Test environment
Provide public IP addresses that will be used for testing the new Web Trader (https://test-webtrader.aix-kz.com) to AIX IT Operation
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.

Notice #3

Dear Trading Members,

We are informing that the upgraded Web-Trader platform is available for testing. We recommend you familiarize yourself with Web-Trader platform within testing period at your earliest convenience.

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.
