Critical Updates

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 is available for testing in the TT UAT environment. 

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:

TT Impact Analysis and Go-Live Plan:

No customer action is required for this release. TT will perform required upgrades the weekend before November 10th and participate in exchange connection testing during the go-live weekend. We will closely monitor all services at startup on Monday, November 10th, and address any issues that may arise.

TT has submitted the Readiness Statement to Eurex as required. 

FMX and FMX_USTF: Optional order fields for Clearing Firm and Position Account

November 17

FMX has added support for specifying the Clearing Firm and Position Account on orders sent to the exchange. TT will add support for these fields in Production on November 17. 

These values are now configurable within Account settings in TT User Setup. FIX users can use FIX party blocks with party role 4 for Clearing Firm and 38 for Position Account.

This functionality is currently available in the TT UAT environment for customer testing.

Eurex/EEX: Self Match Prevention (SMP) and Other Enhancements

December 2025 

TT will provide support for the following Eurex/EEX exchange functionality. 

Enhancement to Self Match Prevention:

On December 1, Eurex and EEX are enhancing the Self Match Prevention (SMP) feature to add 3 new types in addition to the current offering. These new SMP types will be configurable via a new drop down at the Account level in TTUS, and the following values will be allowed:

• Cancel Aggressive and Passive  (Netting , existing model) 
• Cancel Passive (resting order will be cancelled) 
• Cancel Aggressive (Incoming order will be cancelled) 

Order Entry Rejection Based on Eurex Trading Capacity Requirements:

Eurex requires that, for Agency orders, the Client ID field must be populated, otherwise they will be rejected.

For Proprietary or Market Making orders, the Client ID field may remain empty.

TT will now reject orders prior to submission to the exchange under these conditions: 

• Trading Capacity  = Any other capacity (Agency)
• Account Type = A1 – A9 (Required when Trading Capacity is Any other capacity / Agency)
• Client ID = Blank

This change is being made to address reporting concerns from customers when orders are sent to the exchange and are rejected because they do not meet these conditions.

TT will deploy these changes for testing in UAT in late November. 

NZX : Dress Rehearsal / Streetwide tests

November 10 – 15 

During the week of November 10 – 15, NZX will conduct a Dress Rehearsal for customers in the UAT environment in preparation for the launch of the NZX20 Index Derivatives next year. 

During this test, customers may: 

• Test their connectivity to the  exchange
• Place orders and view execution reports for the NZX20 Index Futures contract (TT Contract Code: KIW)

The timing for this test will be from 8:00 AM – 05:00 PM NZT.

Customers who would like to participate in this testing should contact their TT Onboarding representative.

November 16

MIAX Futures has published updated Interface Specifications for the MIAX Futures Onyx trading platform to support enhancements expected to be implemented into production from the calendar date of November 16 (for a trade date of November 17).

JPX : Tick Change for Nikkei Options 

November 17

The tick size table for the Nikkei Options on JPX will be updated on November 17.

This change will be applicable for both – regular Nikkei 225 Options (Product Symbol = 225), as well as Nikkei 225 Mini Options (Product Symbol = 225M).

This change is available in the TT UAT environment for customer testing.

B3: Upcoming B3 FIX Order Entry Gateway Migration – Action Required

November 7 – December 12

B3 has announced a phased reduction of FIX Order Entry Gateways starting in November 2025, affecting certain Derivatives connections. Similar changes in the Equities segment will follow in early 2026. Clients may have already received a notice directly from B3 with the full schedule.

Customers who have received notice that their FIX order entry sessions are affected must ensure the new IPs, Ports, and Target Comp IDs are updated by the date listed in the notice they received from B3.

Customers who would prefer to make these changes before the exchange deadline can contact B3 to have their session IDs migrated to the new destination gateway and would then need to ensure the corresponding TT connections are updated.

NOTE: Customers who have received this notice must complete the required changes by the exchange deadline, otherwise connections will fail to login.

It is strongly recommended that clients perform these updates after the trading session ends and before the next session begins 

For questions, contact B3 at +55 11 2565-5021, [email protected]

Exchange Announcement

Updated: B3: Binary Protocol

March 2026

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 discontinue support for the FIX Order Entry API at the end of Q1, 2026. Customers that have not yet moved to the Binary Order Entry API are strongly encouraged to begin planning for this migration.

WSE: API Upgrade 

TBD

WSE has an upcoming upgrade to their trading system APIs for both market data and order entry. On the Go Live date of this new API, the current API will be decommissioned and the market will be fully migrated to the new versions.

• No functional changes are being implemented on the market data feed for display on TT
• New OTDs of Account Type and Trading Capacity will be introduced, which can be appropriately configured on TT
• TT will support the Self Match Prevention feature introduced along with this upgrade
• Customers are strongly advised to cancel any pending GTC/GTD/GTT orders before close of trading on the last day of the old API

While this upgrade in production was earlier planned for 10 Nov, this date has now been postponed by the exchange, and the announcement on the new date is awaited.

Further details regarding availability of testing in the TT UAT environment will be provided in the near future.

WSE conducted a connectivity test in the production environment on October 4, and TT participated successfully. 

CFE: Upcoming ATS Operator ID Enforcement

December 5, 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 intends to deploy this change to production at the end of the trading session on December 5, 2025. The update will take effect starting with the following trading session, December 7 (Sunday 5.00 pm).

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 the 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.

HKEX: Derivatives After Hours Trading (AHT) Enhancements

Q4, 2025

HKEX plans to introduce the below enhancements to their After Hours Trading (AHT) session in Q4 of 2025 –

• Equity index derivative product coverage expansion for US and UK Holidays
  • Currently, on Memorial Day (US) and Spring Bank Holiday (UK), in the AHT session on HKEX, only the Currency and Metals AHT products are enabled for trading. This will be modified to include all AHT eligible products for trading on these US/UK holidays.
  • On Christmas day, currently, only the Currency products are eligible for AHT session. This will be modified to include all MSCI and Currency products for trading on Christmas day.
  • There is no change to the products that will be available for trading during the Day session on any of the holidays.
• Shortening of the market break between the Day and AHT session
  • Currently, the market break between the Day and AHT session is of 45 mins. HKEX plans to start the AHT session 15 mins earlier, by reducing the market break to 30 mins.
• Widening of AHT Price Limits
  • Currently, the price limits on all futures contracts traded in the AHT session is + or – 5%, and orders outside these price limits are rejected.
  • The stock index futures traded on HKEX will be categorized into 2 baskets – flagship and non-flagship futures. While the initial price limits will be set at + or – 5% for both, those for the flagship products will be subject to a quarterly review, and can be periodically modified by HKEX.
• Index Option – Trade Resumption
  • For the options contracts that are halted due to HKEX’s Trade Halt Mechanism, trading will be automatically resumed based on a deterministic model built by HKEX.
• Enhancement to the reference price determination methodology
  • HKEX will modify their methodology used for determining the reference prices.
• Orders outside price limit boundary
  • For orders entered during the Day session, and which may be outside the AHT price limits (price limits apply only to AHT session) and are carried over to the AHT session, such orders will not be rejected or canceled and can get traded outside the AHT price limits.

None of these proposed changes by HKEX have any direct impact on TT, and will be supported on TT without requiring any additional changes on TT.
