Dear AIX Trading Members,

Further to our previous communications, please find below updated milestones for the upcoming system migration days.

Migration Timeline

• Saturday, 4 April: Trading Members are kindly requested to establish connectivity to the Production platform between 11:00 and 14:00 and confirm accordingly via the Teams channel or by email to [email protected] . Following this, AIX will make the final Go / No-Go decision and relay this decision to Trading Members by email. In the unlikely event of a roll-back decision, all relevant tasks will start immediately.
• Sunday, 5 April: No scheduled activity.
• Monday, 6 April: The pre-opening session will start at 09:30, giving Trading Members additional time to establish connectivity and re-submit their open Orders to the new AIX ME. For the avoidance of doubt, AIX will not migrate or re-enter any Orders on behalf of Trading Members. Trading Members are solely responsible for re-submission of these open Orders to the new AIX ME. Market-Makers are expected to submit quotes in accordance with their obligations.

In addition, please note that the Test environment of the new trading platform will be unavailable from Friday, 3 April, to Monday, 6 April (inclusive).

Important Notice and Disclaimer

Each Trading Member remains solely responsible for ensuring the adequacy of its systems, connectivity and overall operational readiness, as well as for compliance with all applicable requirements. Trading Members are reminded that, pursuant to Rule MR 2.1(4) of the AIX Membership Rules, they are required at all times to comply with the operational, procedural and technical requirements of AIX Trading Facilities and networks, as specified by AIX from time to time. All obligations of Trading Members shall continue in full force and effect throughout the migration period and thereafter, including those arising under the Membership Agreement and the AIX Business Rules.

AIX and its affiliates shall not be liable for any losses whatsoever, including but not limited to losses arising from any loss of connectivity to the AIX ME or other system failure, any errors, delays or interruptions in the transmission, processing or confirmation of Transactions or Information, or any failure by AIX to process or confirm any Transaction initiated by a Trading Member.

Trading Members are strongly encouraged to ensure that all internal testing and readiness checks are completed in advance of migration, that appropriate staffing and technical support are in place throughout the migration window, and that any issues encountered are promptly reported to AIX Market Operations.

AIX will continue to provide updates as necessary, and any queries should be directed to the AIX Market Operations team.

Notice #17 – System migration schedule for April 3 - April 6

The rollover is expected to be completed on Friday evening, and Trading Members will be requested to participate in some light connectivity testing on Saturday.

Please note that all open orders on the close on Friday 3 April will be deleted from the legacy platform at 17:20. It is recommended that Trading Members take a back-up copy of their open orders between 17:05 and 17:20. AIX Market Operations will also perform this same task for all open orders and redundancy purposes.

On Saturday 4 April, from 10:00 to 11:00, all Trading Participants are kindly requested to connect (“ping”) their Order Management System and / or WebTrader to the AIX Production platform and confirm that they have received a response from the server. While no mock-trading session will take place, this step will ensure that connectivity to the Production platform is successful.

For SP1 users: Check availability by pinging 10.20.73.7 (the primary should be available) and 10.20.73.28 (it will be unavailable by ping as it is a backup) and check the ports using the telnet command.

For SP2 users: Check availability by pinging 10.70.25 and 10.70.0.26 and check the ports using the telnet command.

Please note that this easy connectivity test can be undertaken at any time between now and the go-live date and any issue reported to us for prompt resolution.

Around 14:00 on Saturday 4 April, AIX will make a final Go / No-go decision and inform brokers accordingly. In the unlikely event where a rollback procedure is decided, it will be completed on that same day.

AIX will NOT re-inject open orders into the new platform on Monday 6 April. It will be the Trading Members’ responsibility to do so. For that reason, the pre-opening session (when orders may be entered but do not match) will start earlier at 09:30 on 6 April. The market will open at 11:30 as usual.

AIX also informs Trading Members of the following minor functional differences between the current legacy platform and the new system:

• Good-til-Cancel and Good-til-Date orders may be open-ended as opposed to the current 3-month time limit;
• Negotiated Deals (“block trades”) do not require approval from the Market Operations team anymore. Marketable orders will match automatically upon entry. However, the Market Operations team will conduct an intra-day post-facto review and will cancel Negotiated Deals that do not meet the minimum size and prices requirements (minimum size of $50k or currency equivalent for equities, $1m for bonds, the price must be within the high / lows of the day).

Notice #16 – Go-live date confirmation

Dear AIX Participants, 

We are now happy to confirm that the go-live date for the new trading platform will be Monday 6 April. Migration tasks will take place from Friday 3rd April close-of-business until Sunday 5th April. More details will be provided after the Nauryz break. Your participation will most likely be requested on Saturday 4th April.  

Until then, we urge all participants that have access to the Production platform to test and confirm their connectivity via email and the dedicated Teams channel. 

---

Notice #15 – Expected go-live date

AIX hereby informs Trading Members that the go-live date for the new trading platform is set to Monday, April 6th with the system and telco migration taking place over the weekend of April 4-5. 

A final go / no-go decision will be made on March 20th and communicated to Trading Members. 

Further information regarding the detailed migration plan, including potential roll-back options, plan will be shared next week. 

This is why please retain your current version of the FIX software available for rollback. This will be discussed during the Teams meeting next Wednesday on 18-03-2026 where you can share your questions and feedback. 

The Teams meeting invite will be sent today and published via web portal. 

For additional information, please for any questions contact by Customer Portal and at [email protected]

Notice #14

Dear Members,

Please be informed that members acting as market makers for listed securities are required to configure their VPN tunnels to the new production system and check its accessibility by 20 March, if this has not yet been completed. Once the access to the new production system is available, please confirm it by sending an email to [email protected].

We encourage you to use this period to coordinate a convenient time with our IT engineers, who will be available to provide support and assist with VPN configuration, taking into account your specific technical setup.

Please note that if participants are unable to allocate the necessary resources to complete the VPN configuration within the specified timeframe, the go-live date, to be announced shortly, will not be postponed. In such cases, requests for VPN setup may only be considered after the launch of the new trading platform.

Kindly be advised that delays in configuring the VPN tunnel on the broker’s side may affect the ability to fulfil market maker obligations.

Thank you for your cooperation.

Notice #13 - System migration date update

Dear AIX Members,

Thank you for participating in the dry run on Saturday 28 February. It was, in our view, very successful as all participants were able to replicate the functional tasks that are undertaken daily on the current platform.

However, we have made the decision to postpone the migration to a week-end, to be confirmed, after Nauryz and no later than May 1st long week-end. The single reason for this postponement is to give sufficient time to a number of brokers using the FIX protocol to connect to the new production platform.

AIX priority is to ensure a smooth and seamless system transition for all the parties involved. Proceeding with production connectivity on an accelerated timeline could put undue pressure on the network and telecommunications teams of both the brokers and AIX, while not necessarily ensuring that all relevant brokers would be able to establish successfully connectivity. 

Taking a measured and coordinated approach will help safeguard operational stability and support a more reliable outcome for all participants.

We also encourage all Members to use this additional time to keep testing the functional features of the new platform and to report any issue to the Market Operations team.

We thank you for your understanding and will be back shortly with the new date for the go-live weekend.

Notice #12 - Second Dry Run

This approach is intended to assess system capacity and replicate production-level volumes under real-time conditions.

As outlined in Notice 10, if you experience major issues that may require a postponement of the trading platform upgrade, you are required to submit an official request by the end of the business day today.

Thank you for your cooperation.

Notice #10 - First Dry Run Takeaways

Dear Trading Members,

The Astana International Exchange (AIX) appreciates your participation in the initial mutual testing (dry run) conducted on 21 February 2026.

A summary of the key takeaways is provided below.

1. Testing Period
   There is no requirement to request an extension of the testing period for the second dry run. The testing environment remains available on all business days. Members who complete the required testing during business days and successfully finalize the full end-to-end scope may submit the completed checklist to the MKTOPS team via the Customer Portal or by email at [email protected].
2. Participation in Second Dry Run
   Members who successfully completed the full end-to-end testing cycle during the first dry run are not required to attend the second dry run.
3. Members with Outstanding Issues
   Members who encountered issues during the first dry run are required to participate in the second dry run. Please note that the testing environment has been fully available since the date of announcement, and issue resolution testing may be conducted during business days.
4. Connection Option Selection (SP1 / SP2)
   Members who test under SP1 and subsequently request to migrate to SP2 (or vice versa) should be advised that such requests may be queued and addressed after go-live. To ensure an orderly migration process, AIX expects Members to formally select one connection option—SP1 (Modernized) or SP2—and continue testing, configuration, and preparation using the selected option through to go-live. Members are therefore requested to conduct an internal assessment of the testing results and formally confirm their chosen connection option.

Timely confirmation will support structured implementation planning and enable efficient allocation of resources on both the Members’ and AIX’s sides.

IMPORTANT NOTIFICATION, PLEASE READ ATTENTIVELY THE BELOW:

As we get closer to the March 3rd deadline for the go / no-go decision regarding the migration to the new platform, we now request that Trading Members who have an imperious reason to request a postponement of the scheduled migration date inform us by Friday 27/2 close-of-business with a detailed explanation for such request.

Thank you for your continued cooperation.

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.

Dear AIX members,

Please review the updated diagram with available connection options to the AIX test servers.

Depending on your connection settings, please follow these steps:

Brokers using Web Trader:

If you only use Web Trader to submit orders, please access the test Web Trader using the credentials provided by the AIX Market Operations and Connectivity team.

Brokers planning to install SP1 (Upgraded):

If you are using SP1 (Upgraded), please update the test server address to 10.30.253.86 and test market data and order management availability using your FIX SP1 credentials.

Brokers planning to install SP2 (FIX and ITCH):

If you are using SP2, where FIX and ITCH channels are available, please use the corresponding FIX and ITCH credentials. Order management and connectivity should be tested via FIX, and market data availability should be tested via ITCH.

All trading platform participants are required to complete testing of Web Trader (independently), FIX, and ITCH or SP1 (upgraded version) by February 20, 2026. Testing credentials are available upon request to [email protected] or through the client portal (New Web Trader request) at: https://aixops.atlassian.net/servicedesk/customer/portal/6.

Notice #4

Dear AIX Participants,

The test environment for the upgraded AIX MCT FIX Proxy is now available. We ask that you test your current connectors to avoid connection errors after the AIX trading platform upgrade.

Despite technical readiness, AIX has decided to postpone the trading platform upgrade due to participant requests. The new tentative launch date is February 20, 2026.

We believe this postponement will benefit both parties by allowing more time to improve readiness and ensure a smooth transition to the new trading platform.

To test, please complete the following steps:

1. Review the updated MCT FIX Proxy SP1 specifications, noting the gaps highlighted in red.
2. Contact [email protected] to obtain credentials for the updated platform test environment.
3. Provide AIX IT Operations with the IP addresses that will be used for testing the new web trader (https://test-webtrader.aix-kz.com).
4. Obtain test scripts from [email protected] and execute them.

We recommend testing the current system (test web trader and updated MCT FIX Proxy) to identify hidden errors and avoid delays when submitting orders.

---

Notice #3

Dear AIX members,

We are pleased to announce the readiness of the updated Web-Trader platform for testing. We encourage you to familiarize yourself with the Web-Trader platform during the testing period as soon as possible.

The updated FIX SP1 includes changes identified during the initial analysis. Below is an additional 5-point difference:

Difference between the 3rd and 4th generations:	Current: AIX 3rd generation trading platform	Planned AIX 4th generation trading platform
5	All firm-specific execution reports contain tag 11 (ClOrdID) and tag 41 (OrigClOrdID).	Execution reports for the Drop Copy connection do not contain tag 11 (ClOrdID) and tag 41 (OrigClOrdID).

Participants are advised to:

• Review the updated MCT FIX 5.0 SP1 specification and mapping differences (available on the website: https://aix.kz/for–aix–trading–members)
• Conduct testing starting November 26 to identify any impact.
• Make the necessary adjustments to the MCT FIX 5.0 SP1 proxy server on the broker's accounting system to ensure a smooth transition to the new version of the trading platform on December 26, 2025.

AIX MCT FIX proxy outages on 14-Nov-25 and 17-Nov-25	AIX web services unavailability on 18-Nov-25
Dear customers,  Due to internal network problems the AIX MCT FIX proxy service was unavailable from 15:02 till 15:09 on 14-Nov-25 and from 14:47 till 14:54 on 18-Nov-25.  AIX is performing internal investigation on the cause of the problems.	Dear customers,  Due to global outage of Cloudflare CDN service part of AIX web services were unavailable from 16:19 18-Nov-25 till 02:28 19-Nov-25.  All services are restored and fully available.

Should you have related enquiries please contact AIX Market Operations and On-boarding Department at [email protected].

We do apologize for any business disruption.

Notice #2 - Upcoming AIX Trading Platform Upgrade to 4th Generation on December 26, 2025 (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.”

---

Notice #1 - Upcoming AIX Trading Platform Upgrade to 4th Generation on December 26, 2025

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.

If you have any questions, feel free to reach out at [email protected].
