Critical Updates

Clarification on ICE Authorized Trader ID Requirement and Behavior

On June 9, TT deployed the production update removing the legacy behavior on ICE and ICE_L markets where, if the Authorized Trader field was left blank, it automatically inherited the Routing Trader value configured in Setup.

ICE Tag 116, which is used to send both Routing and Authorized Trader values, is a mandatory field. Based on the exchange specifications, our understanding was that both the Routing Trader and Authorized Trader values must be populated; otherwise, the exchange would reject the order. Our initial communications reflected this. It subsequently came to light that this was not accurate. 

Within Tag 116, the Routing Trader portion of the field is required, while the Authorized Trader portion of the field is optional based on the user configuration, however this optionality was not evident in the exchange specification.

Additional details on TT’s implementation of this functionality can be found in the linked document below.

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). 

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 in Production.
• 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.

NOTE: B3 has set the length of the “Entering Trader” value to five.

TT will announce its schedule for the deprecation of support for the legacy FIX order protocol later in 2025.

Updated: HKEX : Disruption in UAT availability

August 2025 

As part of ongoing maintenance in the HKEX Data Center, new HSN network connections between TT and HKEX are being configured. Delivery is expected to be completed by August 1. 

There is no impact expected to Production trading. 

The TT UAT environment for HKEX is expected to be unavailable from August 4 – 8, however, service will be restored sooner if possible. 

Eurex / EEX : New field for PartyIDLocationID

August 2025 

TT will add support for a new tag, ‘PartyIDLocationID’ (Eurex tag 20075), on both Eurex and EEX. The new field will be “Client Branch Country”, and will allow a 2 digit country defined per the ISO definition. It will be used to capture client branch country code, and will be especially useful for EEX admitted members involved in daily transaction reporting . 

This feature will be available for customer testing in UAT in August. 

LSEG: Eurex – RIC rename for 2 digit year code 

Q3 2025

In August / September of this year, Refinitiv (LSEG) will rename Eurex RICs representing Futures and Spread contracts both on Real-time and Reference Data Products to support two-digit year codes. Underlying Futures contracts for Options on Futures will be displayed with a 2 digit year code. This change will also be applicable for Market by Price data, Level 2 RICs and delayed data. 

TT will deploy the required changes to Production before the Refinitiv planned changes in production. These changes are now available for testing in UAT.

All currently deployed versions of TT FIX services are compatible with this change. TT customers using RICs for FIX Order Routing, Drop Copy or Market Data are encouraged to test their FIX applications in UAT prior to go-live.

Eurex/EEX/NODAL : T7 14.0 Upgrade 

November 10

Deutsche Börse will release T7 14.0 to Production on November 10, 2025 across Eurex, EEX and NODAL. Simulation access for T7 Release 14.0 will be available from the exchange on September 1, and TT plans to provide access in UAT as soon as possible once internal testing is complete. 

Additional information from the exchange (including System documentation, circulars and timelines) is available on the T7 14.0 initiative page via the following link: www.eurex.com > Support > Initiatives & Releases > T7 Release 14.0

The following are the anticipated milestones for this project:

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.
