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

April 10 – May 15

B3 has announced a phased reduction of FIX Order Entry Gateways starting in April 2026, affecting certain Equities connections. Similar changes were done for the Derivatives segment in Q4 2025. 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]

HKEX: Derivatives After Hours Trading (AHT) Enhancements

Q2 2026

HKEX will introduce the below enhancements to their After Hours Trading (AHT) session in Q2 2026:

• 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 to the software. 

WSE: API Upgrade

Q2 2026

In Q2, 2026 (date TBD), WSE will upgrade the APIs used 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 Order Tag Defaults (OTDs) for Account Type and Trading Capacity will be introduced, and may be 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

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

LME : TVTIC mapping change 

Q2 2026

Currently, TT uses the TrdMatchID (Tag 880) published by LME to populate the TVTIC value for fills on both the spread and the individual legs. This value is also displayed in the “ExchTransID” column on TTW.

At LME’s direction, TT will modify this logic for leg fills only, so that if the trade is based on an implied TT will use the LegAllocID (Tag 1366) published by LME to populate the field mapped to TVTIC. The TVTIC values used for the spread will not change.

This is planned to be deployed in UAT by May for customer testing.

HKEX: OAPI RHEL library upgrade and recertification

September 2026

HKEX has announced an upgrade to its OAPI library from RHEL7 to RHEL8. While TT will need to make necessary changes to the software for this, this will be transparent to TT customers.
