B3: Binary Protocol

B3 has rolled out new low latency binary protocols for market data via the Binary Unified Market Data Feed (UMDF) and for Order entry (Simple Binary Encoding (SBE).

TT has already migrated its Market Data to the binary UMDF protocol and, for order entry, currently supports both the legacy FIX API and the new binary API.

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- Completed: TT upgraded its Market Data feed to use the new Binary UMDF protocol.
• Phase 2- In Progress: Customers can continue using their existing FIX order connections while also having the option to configure new binary API connections. 
• Phase 3- Future: TT will discontinue support for the legacy FIX order entry API, requiring all customers to use the Binary Order Entry API connections. Any GTC/GTDate orders resting on legacy FIX connections will be canceled when the cut-off occurs.

NOTE: B3 has set the length of the “Entering Trader” value to five on the Binary Order Entry API.

TT will announce the deprecation date for the FIX order entry API later in 2025.

CFE: Upcoming ATS Operator ID Enforcement

Q4, 2025

To ensure compliance with CFE Rules 403(b) and 303A, TT will update system behavior related to the handling of Operator IDs (OEOID – FIX Tag 25004) for manual and automated orders.

As part of this update, TT will:

• No longer substitute the Manual Operator ID when the ATS Operator ID is not configured
• Omit Tag 25004 if the applicable Operator ID is missing, which will result in order rejection by CFE

TT plans to deploy this update in Q4 2025. A specific effective date will be announced in a future notice.

Required Action in TT Setup

To ensure compliance with CFE rules, and to avoid order rejections once software changes are implemented later this year, customers should review the User configuration in TT Setup and verify that the following fields are populated as needed:

• Manual Operator ID: Used for manual order entry
• ATS Operator ID: Used for orders submitted via automated trading systems

These are separate fields and must be configured independently. 

Order behavior is as follows, based on TT Setup configuration:

• If only the Manual Operator ID is configured:
  • Manual orders will be accepted
  • Automated orders will be rejected by CFE (Tag 25004 not sent)
• If only the ATS Operator ID is configured:
  • Manual orders will be rejected by CFE (Tag 25004 not sent)
  • Automated orders will be accepted
• If both Manual and ATS Operator IDs are configured:
  • Manual orders will be accepted
  • Automated orders will be accepted
• If neither field is configured:
  • All orders (manual and automated) will be rejected by CFE

If you are unsure of your current Operator ID configuration or need assistance updating Setup, please contact your TT Onboarding representative or TT Support.

Eurex: TLS Upgrade 1.3 

Q1, 2026

Eurex launched support for TLS 1.3 in October 2023 and has continued to support TLS 1.2 and TLS 1.3 in parallel. Support for TLS 1.2 will be decommissioned in Q1, 2026.

Currently, TT supports TLS 1.2 and will upgrade to TLS 1.3 in advance of the decommission date.

Customer Impact: There will be no impact on the customer experience, and no action is needed from customers.
