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 in upcoming System Updates. 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.

CFE: RIC symbol change

March 29

Effective 17 March 2024, Refinitiv has introduced a change to RICs for CFE VX and VXT products transitioning from single digit to two digit year codes for contracts expiring in January 2024 and beyond. Example: Old RIC: VXF4, New RIC: VXF24.

Please note that TT did not go live with these changes at the same time as Refinitiv. TT will support new RIC codes in Production starting April 1st. Until then, customers should continue to use the existing RIC codes. 

Once changes are implemented, TT will modify the RIC codes of existing contracts and any new contracts as they are added by the exchange. This will impact customers that trade CFE using FIX Order Routing, Drop Copy and FIX Order Gateway services, and will require that clients be ready to both send and receive the new RIC code format.

This change was made available in UAT for testing as of March 15, 2024.

All TT FIX Order Routing, Drop Copy and FIX Order Gateway clients using RICs on the CFE market are strongly encouraged to integration test their applications in UAT before the production go-live date.

Please contact with any questions or concerns.

IDEM: Migration to Euronext Go Live Weekend Test

March 23

In preparation for the migration of IDEM instruments to Euronext Optiq, Euronext will conduct a final dress rehearsal in their production environment on March 23. Customers can participate in this dress rehearsal by logging onto the link – using their production login credentials. 

  • Customers may use their existing Euronext connections / logical accesses to trade on the IDEM instruments. 
  • In Setup, Administrators will be required to permission users for access to IDEM market data on Euronext, as well as to allow trading.
    • In case the IDEM permissions are grayed out, administrators are requested to reach out to their TT Onboarding representatives to help grant permissions for editing the IDEM subscription for their company.
  • The OTDs and Risk Limits that are currently configured for the IDEM exchange were copied over to Euronext on 15 Mar. Customers are encouraged to verify this data, and to make any modifications necessary for trading

For the Go-Live Weekend, along with the IDEM instruments, TT will also make corrections to strike prices on legacy Euronext instruments. Hence, the upload will be done in 2 phases –

  • Instrument upload for IDEM instruments will be started first and expected to complete around 1100 CET. TT platform will then be available for market data and order entry.
  • Instrument updates for legacy instruments will be started post the above step, and expected to complete by 1300 CET.

 The schedule for this mock is expected to be as follows:

Time (CET)Activity
0900Euronext Optiq System will come up. TT will start instrument upload for both IDEM as well as legacy Euronext instruments
1030Call phase starts

IDEM: Migration to Euronext

March 25

On March 25, Euronext will complete the migration of Borsa Italiana (IDEM) products to the Euronext exchange. On TT, the IDEM market will be decommissioned and these products will be available to trade on the Euronext market. 

Details on TT customer impact, as well as TT’s plans for this migration may be found in the IDEM to Euronext Migration Guide, which will continue to be updated as needed:

NOTE: To reduce the manual effort required on the part of customers, on February 9, TT copied TTUS data in UAT from IDEM to Euronext. Customers are encouraged to verify this data, and to make any modifications necessary for trading. 

This risk migration was performed in Production after the close on Friday, March 15th. Please refer to the migration guide, page 9, for additional information on this data migration. Customers should validate any and all Risk setup for users as soon as possible prior to March 25.

Notable changes with this migration:

  • In addition to the currently supported Euronext order types of Market and Limit, Stop Market and Stop Limit will be enabled for IDEM Derivatives, and will be supported on TT. 
  • TT will introduce support for the Euronext Self-Trade Prevention (STP) functionality, which will be supported on both Euronext and IDEM products. 
  • In Setup, Administrators will be required to permission users for access to IDEM market data on Euronext, as well as to allow trading.

These changes are available in the TT UAT environment for testing.

The following are the anticipated milestones for this project:

Euronext: Support for Euronext’s Self Trade Prevention (STP) Functionality

March 25

TT will implement support for Euronext’s Self Trade Prevention (STP) functionality on March 25, 2024. This is now available in the TT UAT environment for testing. In TT User Setup, users can set the SMP ID and SMP Instruction for this functionality to take effect. SMP Instruction can be set to any of the below options –

  • Cancel Resting Order
  • Cancel Incoming Order
  • Cancel Both Orders

Customers trading on TT through FIX will need to use TT FIX Tags 7928 and 8000 for SMP ID and SMP Instruction respectively. Please refer to the TT FIX Tag Directory for further details on these two tags.

Please note that the Euronext Self Trade Prevention is not applicable for orders sent with an Account Type of Client.

TFEX: Extended Trading Hours

March 25

TFEX has announced plans for Phase 2 of their extension of trading hours for Non-Equity Products. The changes are scheduled to go into effect on March 25, 2024.

TT Platform Impact

There is no impact to the TT platform. Since TT TFEX services already stay connected to the exchange past the new Non-Equity Products‘ closing time, no changes are required. Furthermore all market updates like Trading Status updates, etc are detected by the TT platform automatically and do not require changes when schedules change.

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). 

TT upgraded the market data in UAT on March 20, 2024, to utilize the new binary price feed.

The exchange requires new credentials for order entry via the new API. We recommend that customers initiate the process of requesting these credentials from the exchange.

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

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

TT has completed the conformance with the exchange for Order Entry and Prices data. We will provide a milestone-based timeline detailing dates and deliverables for each of these phases in the upcoming week.

Please note that on the new binary SBE UMDF market data protocol, B3 does not send Settle and SettlePU prices. B3 plans to address this issue in Q2, with the solution becoming available to ISVs in Q3. These values are crucial for calculating PnL and working days to expiry for ADL. To address this issue in the new protocol, TT will implement an interim solution to retrieve Settle and SettlePU from the old protocol at the beginning and end of each trading session. These values will remain constant until the end of the trading session and won’t be updated in real-time. Once this feature becomes available via the new protocol, these values will once again be updated in real time.
