SPX, VIX, and XSP may be traded in all sessions (GTH, RTH, and Curb), while all other products are limited to RTH only. - Session eligibility sets which trading sessions the account can trade in. This can be configured on TTUS -> Accounts Features supported: - Strategy creation - TT FIX API - Cancel on Disconnect (configured at the exchange) Clients are recommended to set the port attribute "Report Working Prices", "Cancel on Disconnect", "Carried Order Restatements", "Done for Day Restatements" with the exchange. Price Adjustment Due To NBBO: If the limit price of an order does not cross the NBBO, the order will be displayed at the price at which it is placed. If the limit price of an order crosses the NBBO, the limit price will be adjusted on entry to the locking price of the NBBO. This adjusted price is sent in WorkingPrice (tag 9690). TT will adjust the working price of the order in the order based on WorkingPrice. TT recommends that all users set the port level attribute ‘Report Working Price’ to Yes to receive the ‘WorkingPrice’ of the order in tag 9690. If the NBBO widens, the displayed price will be readjusted according to the new price band. When this happens, Cboe does not send restatements or notifications for the new adjusted price. The user on TT will continue to see the initial working price.

04/17/2025	04/17/2025	Improvements	Trade App on TT (desktop)	We have released a new TT Desktop installer package v25.0.0 that utilizes Chromium v131.

04/15/2025	04/15/2025	Improvements	Exchanges	A separate market of FMX_USTF is now available on TT. Trading on the US Treasury Futures that will be launched by FMX shortly, will be supported on TT through this market. Customers interested in trading on this market should contact their TT Onboarding representative. Functionally, this market will support the exact same features supported on the existing FMX market on TT, which will continue to support the SOFR futures traded on FMX. (Ref 180180)
04/11/2025	04/14/2025	Improvements	Exchanges	LSEG : Eurex - RIC rename for 2 digit year code - FIX Order Gateway On April 14, 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.

TT will deploy the required changes to Production after the close on Friday, April 11. Changes are available now for testing in UAT. The change is compatible with all currecntly deployed versions of TT FIX Order Gateway. TT customers using RICs for FIX Order Gateway are encouraged to test their FIX applications in UAT prior to go-live. (Ref 179793)
04/11/2025		Plan	Exchanges	Coinbase Derivatives (CDE) Primary Data Center Migration to Chicago-Cermak Coinbase Derivatives (CDE) exchange is relocating its Primary Data Center from Aurora to Chicago-Cermak, with a hard cut scheduled for April 25, 2025, in Production. GTC/GTDate orders are expected to continue working as usual after the migration. The endpoints (IPs and ports) for order entry will remain unchanged in Production. No action is required from clients for this migration. TT is planning to perform the migration on Apr 11, 2025 (Friday) end of the day. (Ref 179142)
04/09/2025	04/09/2025	Improvements	Exchanges	USTF instruments are now available on the FMX market for dress rehearsals testing. Since this mock trading on US Treasury Futures will happen in parallel to the live trading on SOFR futures, it is strongly recommended that a separate account be set up on TT for trading the USTF, so that the SOFR and USTF PnL can stay on separate accounts. TT also recommends that only the USTF test instruments (which will be indicated by TF in the instrument display name) be used for this testing. The USTF instruments will be tradable through the FMX market till EOD of 11 Apr. From 16 Apr, these will be available on the separate market of FMX_USTF on TT. (Ref 180038)
04/04/2025		Improvements	Score	New feature: Audit trail download for data reconciliation. Users will now see a new section under the report tab where a single day can be selected for an audit trail download. When the user selects the date and clicks ok, all data received by TT for that trade date will generate into a zip file that can be downloaded. This process may take a few minutes and users can navigate away and check on the progress. Once downloaded the user will extract from the zip and will 24 csv files within the new folder. Each file represents one hour of trading. The data will have every event, even those that are not considered at score processing such as implieds/legs of exchange spreads. Whether an event was considered in score processing will be noted in the column "valid record", with 1 meaning it was considered for Score processing, and 0 meaning it was not considered during score processing. If an event has a 0 in this field there will be a reason stated in the column next to it entitled "invalid reason". We recommend all admins use this report on a semi regular basis to ensure the all data expected to be surveilled is making it to TT. This will identify issues like accounts that are not being included in drop copies due to misconfigurations or other set up issues that cannot be detected on the TT side. (Ref 180282)
