Critical Updates
(Updated) CME: Mandatory Migration to iLink 3.0 – Available in Production
November 15, 2024
Update: In anticipation of the seasonal change freezes beginning in December, and the potential penalties imposed by CME for not migrating to iLink 3.0 by the end of 2024, TT has established a deadline of November 15, 2024, for all clients to complete their migration to CME iLink 3.0 on the platform. Support for CME iLink 2.0 will end after this date.
Summary: 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.
Convenience Gateway Migration from iLink 2.0 to iLink 3.0: Customers familiar with the MSGW iLink3 upgrade that occurred in 2019 will find the CGW iLink upgrade familiar. The steps for migrating are as follows:
- Coordinate with CME to apply for an iLink3 Convenience Gateway Session.
- When applying for a new iLink3 Session, Members should specify TT frontend name “TT CME iLink3 CGW”
- For each iLink Session, create NEW Connections in Setup
- Be sure to use a Session ID created by CME specifically for iLink3 (see #1 above).
- Be sure to set the Connection Type to “Convenience Gateway iLink3.”
- PLEASE NOTE: Modifying an existing connection’s “Type” (for example, changing a connection from “Convenience Gateway” to “Convenience Gateway iLink3” is not supported. All Customers migrating from iLink2 to iLink3 must create a new connection for iLink3.
- FIX configurations, Order Tag Defaults, etc. will all continue to function with no changes required since the functionality of TT CGW iLink3 is identical to TT MSGW iLink3.
- Throttle Limits
- For On-Demand order entry, TT recommends that customers set their Connection level Max Order Rate to 250 transactions per second in order to ensure CME iLink session throttle limits are not exceeded.
- This limit will be applied to New Order Single and Change messages, but Cancel messages will not be throttled by TT
- Note: Cancel messages are accounted for in the rolling transaction per second queue, but will not be rejected by TT
Access to Testing: Convenience Gateway for iLink 3.0 OnDemand Order entry is available now for testing in UAT. Members who have not yet started verifying iLink 3.0 are strongly encouraged to begin testing as soon as possible.
Access to Production: Convenience Gateway for iLink 3.0 OnDemand order routing is available now for Production Trading. Members are welcome to begin migrating as desired. User Acceptance Testing prior to migration is highly recommended.
Please note: GTC orders will not persist when moving from an iLink 2 connection to an iLink 3 connection. TT recommends that, where possible, customers place GTC orders via iLink 3 sessions as they prepare to fully migrate to iLink 3.
Documentation/ iLink3 Migration Guide: The TT CME iLink3 Migration Guide is now available at the link below.
Pre-Registration vs On Demand Order Support: At this time, TT Support of CME iLink 3.0 is limited to OnDemand Orders only. However, TT Engineers are currently working to complete support for the exchange’s new “Pre-Registration” Order entry method. Details about TT handling of Pre-Registration, including implementation details, Max Order Rate settings and delivery schedules are provided in iLink3 Migration Guide.
Prior to TT’s Production launch of Pre-Registration Support, customers will have the opportunity to participate in Mock sessions which we will coordinate with the CME.
Further updates regarding timelines, migration, documentation, etc will be shared here in System News.

The following are the anticipated milestones for this project:
| Milestone | Expected Date | Delivered Date |
|---|---|---|
| Exchange Upgrade Announcement | 6/22/2024 | 5/27/2024 |
| Exchange Preliminary Release Notes | 7/22/2024 | 7/22/2024 |
| Exchange Preliminary Specifications | 8/6/2024 | 8/6/2024 |

| Exchange Go-Live | 11/18/2024 |
TT Impact Analysis and Go-Live Plan:
There is no action required on the part of customers as a result of this release. TT will perform the necessary upgrades the weekend prior to Nov 18, and will participate in exchange connection testing during the go-live weekend. We will closely monitor all services at startup on Monday, Nov 19, and take any action necessary to resolve any issues which may arise.
TT will submit its Readiness Statement to the exchange in due course, once testing is completed.
Additional notes on this upgrade:
- With T7 12.1, Eurex had announced an enhancement to Self-Match Prevention. TT will add support for SMP after T713.0 go-live.
- Additional details on this functionality may be found in the Eurex Functional Technical Release Notes
- TT will provide a more concrete timeline for release of this feature in the near future, and will communicate implementation details at that time
B3: Binary Protocol
Q4
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: https://library.tradingtechnologies.com/release_notes/uat-2024-03.html
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 in Q2, with the solution becoming available to ISVs in Q3. To address this in the new protocol, TT is implementing 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.
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: https://library.tradingtechnologies.com/release_notes/uat-2024-04.html
* All clients are strongly encouraged to conduct in UAT and provide feedback.
Migration Documentation: https://library.tradingtechnologies.com/downloads/B3_Binary_Protocol_Migration_Guide.pdf
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:
| Milestones | Expected date | Delivered date | Notes |
| TT conformance with B3 for Binary Market Data | February 21, 2024 | February 21, 2024 | |
| TT conformance with B3 for Binary Order Entry | February 29, 2024 | February 29, 2024 | |
| Deployment of Binary Market Data to UAT | March 19, 2024 | March 19, 2024 | |
| Deployment of Binary Order Entry to UAT | April 2, 2024 | April 2, 2024 | TT will provide support for both legacy FIX and Binary protocols |

| Phase 1: Deployment of Binary Market Data to Production | June 28, 2024 | June 28, 2024 | Phased deployment of the B3 product database will be carried out after Phase1. More details will be provided in the note below. |
| Phase 2: Deployment of Binary Order Entry to Production at the end of the trading session. | November 8, 2024 | TT will provide support for both legacy FIX and Binary protocols | |
