Critical Updates

TTFIX.crt Update Notice 

July 11 

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
• SIM: 2025/06/27
• Production – New York only: 2025/07/11
• 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

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). 

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.

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.

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.

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 would be available for customers to test in the UAT environment in early July . 

LSEG : Eurex – RIC rename for 2 digit year code 

Q3 2025

In Aug / Sep 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. 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.

The TT platform currently works on TLS 1.2 . We are working actively to ensure that we upgrade to TLS 1.3 before decommissioning .

New Markets

Cboe Equity Index Options

May 9, 2025

On May 9, TT launched access to Cboe equity index options, including support for standard options on popular Cboe products such as the S&P 500 Index (SPX), Cboe Volatility Index (VIX), Russell 2000 Index (RUT), and Mini-SPX (XSP).

Support for complex instruments (strategies) and strategy creation via the TT platform will be introduced at a later stage. We will communicate the timeline for this enhanced functionality as soon as it is finalized.

Access to Cboe equity index options is currently available in TT UAT.

Supported features:

• Standard TTW, TT desktop order routing
• FIX API and .NET SDK
• Options only (Futures, Spreads, and Strategies are not included)

Currently unsupported features:

• Exchange created strategies
• Strategy creation from TT
• Auto tools (ASE, Aggregator, ADL)
• TT Order Types, TT Premium Order Types
• Charts
• Options chain and advanced options features

Support for option strategies and strategy creation will be introduced in the coming weeks.

Clients must configure the following settings for their FIX order entry ports with the Cboe:

• Report Working Price: Yes
• Carried Order Restatements: Yes
• Done For Day Restatements: Yes

With regard to the ‘Report Working Price’: TT recommends setting this to Yes so that if Cboe changes the order’s price due to NBBO rules, TT will receive the updated working price in tag 9690. The order book will then reflect this adjusted price. If this setting is not enabled and Cboe adjusts the price, the user will not see the updated price in the order book. When the NBBO widens, Cboe may update the price again but does not send any notifications or restatements. When this happens, TT users will continue to see the original working price instead of the adjusted one.

With regard to Carried Order Restatements and Done For Day Restatements: These attributes must be set to Yes for GTC and GTDate orders to persist across sessions.

NZX: NZX 20 Index Futures Relaunch Project

Q3, 2025
