CME: Mandatory Migration – iLink3 Binary Order Entry Protocol for CGW


CME has introduced support for iLink3 on Convenience Gateways (CGW) for trading Futures and Options on CME Globex. CME will decommission CGW iLink2 on Jan 31, 2025 however,  all customers must migrate by December 31 of this year to avoid penalties. 

Development of TT iLink3 Convenience Gateway support is now under way. Customers familiar with the MSGW iLink3 upgrade that occurred in 2019 will find the CGW iLink upgrade familiar.

TT’s plans for support of iLink 3.0 for CGW are as follows:

  • iLink 3.0 CGW On-Demand Order Entry
    • UAT – End of May: Support for On-Demand order entry on iLink 3.0 and the initial deployment to UAT is scheduled for the end of May, 2024. 
    • No FIX tag changes for Order Entry or Drop Copy are currently expected with this release
  • iLink 3.0 CGW Pre-Registration Support
    • UAT –  Summer, specific details to be published in the near future

Prior to Production launch on TT, we will provide customers with the ability to participate in Mock testing sessions which we will coordinate with the CME, details to be communicated at a later date. 

Further updates regarding timelines, migration, documentation, etc will be shared here in System News.

B3 Binary Protocol


B3 has introduced new, lower latency Binary protocols for Market Data via the Unified Market Data Feed (UMDF) and Order Entry via Simple Binary Encoding (SBE). 

On March 19, 2024, TT upgraded the B3 Binary market data protocol in UAT, the release note can be found here:

On April 02, 2024, TT deployed the new Binary Order Entry API in UAT. Customers should contact B3 for credentials to be used with the new API. The release note can be found here: 

* All clients are strongly encouraged to conduct testing in UAT and provide feedback.

Migration Documentation:

Please note that B3 continues to support the legacy protocols in parallel with the new Binary offering, and the TT migration will follow a phased approach:

  • Phase 1: TT will update its Market Data feed to use the new UMDF protocol, which is compatible with both the new SBE Order API and the legacy order entry protocol – no changes are expected for end users. This is completed and available in UAT.
  • Phase 2: TT will allow customers to continue using their existing order connections, and in parallel will allow customers to configure and use new connections using SBE. 
  • Phase 3: TT will discontinue support of the legacy orders API, and customers will need to utilize new SBE connections. Please note that any GTC/GTDate orders on legacy connections will be canceled when we cut off support for the old API.

The following are the anticipated milestones for this project:

SGX: Service Release 12

April 29

SGX has announced plans to deploy a new system update, “Titan DT/DC Service Release 12” which includes security improvements and fixes to SGX’s derivatives trading and clearing platform. 

There is no impact to the TT platform in SGX SR12. The exchange is adding a new field to their Fill/TradeCaptureReport message but it’s a message field which has no use or applicability on TT since it is specific to capturing  SGX_GIFT trades on SGX which is not possible on the TT Platform.

The other changes being put into place for SR12 are exclusive to SGX Derivatives Clearing Systems (PTRC, etc), and these are neither supported on nor accessible from the TT Platform.

For TT customers there are no steps to take or tests to complete. There will be no change in functionality or platform behavior as a result of SR12. Customers are welcome to conduct routine testing in the UAT environment to verify, but using the TT Platform there is no way to observe or access the SR12 changes directly.

April 29

TT platform requires no changes to support this improvement as it is simply an extension of the same implied / bait matching that already happens in production on other products such as EUR/CNH Futures (EC) and TSI Iron Ore CFR China 62% Futures (FEF).

TT has completed internal testing of the platform to ensure that TT Users are able to take advantage of the new arrangement starting immediately from day one.

HKEX: Self-Match Prevention Service Enhancements


HKEX has announced enhancements to their Self-Match Prevention Service which will expand the methods of utilizing and accessing the SMP feature. The exchange has tentatively scheduled the enhancements for a production launch in June, 2024. 

Presently, the estimated delivery timeline for UAT testing of the SMP Enhancements is during the last week of May, 2024. Prior to launch, all Participants planning to use the new features are required to complete a Readiness Test.

  • Self Match Prevention (SMP) IDs must be issued by the exchange
    • During SMP ID registration, the SMP Instruction / Behavior (passive or aggressive) is set and cannot be changed
    • Accessing both Passive and Aggressive requires two separate SMP IDs.
  • On TT, “Self Match Prevention ID” will be configured in Accounts → HKEX → Exchange Properties
  • FIX Impact:
    • SMP overrides will be available on FIX New Order (D /AB) , Cancel/Replace (G / AC) and TradeCaptureReport (AE) messages by sending Tag 7928 (SelfMatchPreventionID) on HKEX
    • SMP ID values will be reported in Tag 7928 for Execution Reports (8), TradeCaptureReportAcks (AR) and TradeCaptureReports (AE) when an SMP ID is specified on the order.

    • created during an auction state (such as Pre-Open) OR
    • matched due to it being created during Pre-Open and the product transitions into Open

Please note that the already-existing HKEX SMP implementation will continue to operate normally on TT, with no changes, both before and after the rollout of the exchange’s new enhancements.
