TT has added support for the exchange implied prices on the MIAX_FUT_CH market on TT.
(1) Exchange supports implied prices only on the outright futures, and hence no implied prices will be displayed on the spread market.
(2) When a spread order trades with individual leg orders, market updates are sent by MIAX on the individual legs only, and no market update is sent on the spread. Hence, the market updates on the spreads are synthetically generated on TT. As confirmed by MIAX, this trading of spread order with individual leg orders will be supported only for calendar spreads, and hence, this logic to synthetically derive the spread market updates is applied by TT on the calendar spreads only.

LSEG : Eurex - RIC rename for 2 digit year code
In August or September this year, Refinitiv (LSEG) will rename Eurex RICs representing Futures and Spread Contracts on their Real-time and Reference Data Products to support two-digit year code. Underlying Futures contracts for Options on Futures contracts 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.
The change is compatible with all currently deployed versions of TT FIX services. 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.

Order Entry |
TT / ICE Authorized Trader Requirements [TTUS-> Users -> Exchanges -> ICE -> Authorized Trader]
Please be advised that, TT will implement a mandatory system update on June 9, requiring all customers to populate the Authorized Trader field for ICE and ICE_L user configurations. Currently, TT copies the Routing Trader value to this field if it is left blank. While this accommodates the use case where the Routing Trader and Authorized Trader should match, it can result in incorrect values when these two fields should not match.
Before close of business on June 6, 2025, customers must review their ICE configurations and populate the Authorized Trader field. TT will stop automatically copying the value, and the Authorized Trader fields will either be left blank or use the value specified by the user. This change is required for exchange compliance. Please refer to the attached instructions for updating this field.

TT has added support for the night session of KRX which has a go live date of 9 Jun.
The session time for the night session will be from 18:00 to 06:00 KST and will be held from Monday to Friday.
The products supported on the night session will be as follows:
KOSPI 200 Futures/Options (Symbol - K2I)
Mini-KOSPI 200 Futures/Options (Symbol - MKI)
KOSDAQ 150 Futures (Symbol - KQI)
KOSPI 200 Weekly Options (Symbol - WKI, WKM)
USD Futures (Symbol - USD)
3Y KTB Futures (Symbol - BM3)
10Y KTB Futures (Symbol - BMA)
Since the order entry exchange channels for the day and night sessions will be separate, customers will need to ensure they have appropriate logic at their end to route orders to the appropriate exchange channels / endpoints. There will not be any indicator on the TT FIX order gateway messages to indicate whether the order is for Day session or Night session.
