08/15/2025

Improvements

Trade Surveillance

The model identifies and scores potentially abusive market behavior related to the Indicative Opening Price (IOP) during the pre-market open period on CME. It specifically looks for instances where buy orders are placed above the current IOP or sell orders are placed below it ("crossing the IOP"). If such a crossing occurs and the order is subsequently canceled before market open, the model assigns a high score, with higher scores for multiple cancellations after an initial crossing.

08/11/2025

09/18/2025

Improvements

General

We have added more resiliency to handle network disruptions and failures when communicating with TT back end services. Specifically, improvements were made to better handle disruptions when creating manual fills, posting updates from the Position Manager widget, and using OMS features from the Order Book and Orders and Fills widget (OFW) such as care order locking, unlocking, bulking, stitching, splitting and releasing and allocating fills.

(Ref 182504)

09/18/2025

Fixes

Order Book

Fixed an issue that sometimes caused the Order Book to display rejected orders from previous sessions.

(Ref 182503)

08/11/2025

09/18/2025

Improvements

Order Entry

Currently, when launching an order entry widget, e.g., an Order Ticket and/or MD Trader, to configure an order, if a default account in Order Profiles is NOT populated for a market, TT software automatically seeds the order entry widget with the first account from the list of accounts available for that market. Some users feel that this "auto-seeding" behavior can potentially cause user errors trading into incorrect accounts, and instead would like TT to require selecting an account before placing an order. To achieve this, we have enhanced the current behavior when using the Preference > Orders > "Seed blank account for profile without associated account in Setup", to always force the user to select an account when (1) The selected Profile does not have an account assigned to it in TTUS, or (2) More than one account is available for the profile/market combination. As part of this work, we have also added a Company level setting in Setup (OFF by default) that controls that TTW Preference. When this new setting is enabled in Setup, TTW will enable the Preference and not allow the user to disable it. If disabled in Setup, TTW will allow the user to enable/disable the preference in TTW.

(Ref 182497)

09/18/2025

Improvements

General

We have improved the startup and initialization process of the TT front application to be more resilient to network disruptions and failures.

(Ref 182495)

08/11/2025

08/11/2025

Improvements

Orders

We now support "Soft Limit" pre-trade risk thresholds that can be set by administrators in Setup. This extends the current ability to set these locally by users in TTW Order Profiles. These limits provide notifications when certain risk levels are approached, but they do not automatically prevent trades. See our documentation for more details.

Fixes

Exchanges

TT has released a fix to display the Volume, LTP and LTQ on spreads as per the trade messages received from MIAX. These attributes will be updated as below - - For a spread vs spread trade, the Volume, LTP and LTQ will be updated on the spreads only. These will not be updated on the leg instruments - For a spread order that trades with the legs, the Volume, LTP and LTQ will be updated on the outright futures (legs) only. These will not be updated on the spreads

(Ref 184725 ) LME has recently launched TAS instruments for 6 products (Aluminium, Zinc, Copper, Lead, Tin and Nickel) in UAT. LME does not support creation of strategies on these instruments.
When using the Strategy Creation widget to create a new strategy for the non-TAS instruments, if the expiry for one of the legs is same as the expiry of the 3M instrument and a weekly instrument in that case the widget wrongly picks up the respective TAS instrument for that product. If the trader now clicks on the "Create" button , the strategy cannot be created and the Exchange returns an error saying "LME_NTP Exchange rejection : 5030 duplicate strategy.
Workaround : Instead of selecting the date for the 3M / Weekly contract, if a trader clicks on the "3M" button , then the correct instrument will be selected and the strategy can be created successfully
Solution : TT is currently working on a permanent solution and will communicate the deployment dates in the near future.
