Critical Updates

TTFIX.crt Update Notice 

July 18 

For customers whose FIX engine natively supports SSL encryption, or who have implemented FIX session encryption using STunnel, TT provides a TTFIX.crt file with the public certificates used by the TT platform FIX endpoint. These certificates expire on an annual basis and must periodically be refreshed to continue functioning. 

On June 13, TT updated the stunnel.zip file located in the Download Center in order to update the soon-to-be-expired certs in the TTFIX.crt bundle. All TT customers who use STunnel must download the new zip file and apply it at any time before the new zip file update is applied in each TT environment, which will be: 

• UAT: 2025/06/20 – COMPLETED
• SIM: 2025/06/27 – COMPLETED
• Production – New York only: 2025/07/11 – COMPLETED
• Production – All data centers: 2025/07/18

Customers still using the old stunnel.zip file after the dates listed above will not be able to connect to the respective TT environments. 

Added TT Platform STAR.TRADE.TT; valid from 2025/06/01 – 2026/06/01 

Please download the updated stunnel.zip here after June 13: https://library.tradingtechnologies.com/tt-fix/general/stunnel.zip 

Directions for downloading the updated stunnel.zip and configuring a stunnel FIX session with TTFIX.crt can be found on the TT FIX Help Site here: https://library.tradingtechnologies.com/tt-fix/general/Managing_FIX_Sessions.html

Introducing the New TT Customer Portal

The TT Customer Portal will launch in September with a modern and intuitive experience that will allow you to access essential TT applications, support tools, documentation and training resources from a single, centralized location.

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.

HKEX : Possible disruption in UAT availability

Aug 2025 

As part of the HKEX Data Center migration, new HSN network connections between TT and HKEX are being set up. This activity is expected to be completed by 1 Aug. While there is no impact to any live trading, there is a possibility of the TT UAT environment for HKEX to be unavailable for 5-10 business days from Aug 1. Customers will be kept informed of the UAT availability during this period through our customer service teams.

Eurex / EEX : New field for PartyIDLocationID

Aug 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 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 Manual Operator ID is configured:
  • Manual orders will be accepted
  • Automated orders will be rejected by CFE (Tag 25004 not sent)
• If only 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.
