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. 

TT plans to support iLink 3 for CGW in UAT in Q2, 2024. Additional details on support for this migration will follow next week. 

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. 

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. At the present time TT has set July, 2024 as the tentative target for the start of testing in UAT. Further updates regarding timelines, migration, documentation, etc will be shared here in System News as the details become clearer.

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

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.
