01/29/2026	03/31/2026	05/28/2026	Improvements	Order Book	Added a feature within the Order Book widget, where if the last known status of an Order (native or child of synthetic parent) is “Working”, and exchange order connection goes down, the order row will be greyed out. Once exchange order connection is re-established, the order will be visible and not greyed out. (Ref 198147)
01/29/2026	03/31/2026	05/28/2026	Improvements	Orders	In the Product Grid and Depth widget, when an order is working in an instrument, the user shall be able to launch the Floating Order Book (FOB) directly on the bid or ask cell. The FOB will launch based on the method defined in the global Preferences > Orders page in the "Floating Order Book" section. (Ref 198146)
01/29/2026	03/31/2026	05/28/2026	Improvements	Orders	Added functionality within the Depth widget where the Depth widget right-click Settings dialog shall include a "Highlight my orders in depth" checkbox item, located immediately above the current "Show tabs" checkbox item. When enabled, this setting will highlight the BidQty or AskQty cells of orders that match the 'Current User' on each order. Default colors will be the same as the current yellow background color and black text used for the “Price update highlight background” setting. (Ref 198145)
01/29/2026	03/31/2026	05/28/2026	Improvements	Positions	Added an improvement to EPEX and Nordpool positions display within the MD Trader and Market Grid widgets to display quantity in MWh. This was previously displayed in KWh. (Ref 198144)
01/29/2026	03/31/2026	05/28/2026	Improvements	Orders	Added functionality within the Product Grid widget to "View my orders only" that is currently available in the Market Grid widget. The Product Grid right click Settings dialog shall include a "View my orders only" checkbox item, located immediately above the current "Highlight my own orders in depth" checkbox item. When enabled, the setting filters the Product Grid display for working orders based on the 'Current User' on each order. (Ref 198141)
01/29/2026	03/31/2026	05/28/2026	Improvements	Order Entry	Added functionality within the Floating Order Book specific to keyboard workflow and price focus. 1. The Floating Order Book (FOB) shall respond to keystroke presses, specifically: (i) Esc (Escape) = close the FOB (ii) Tab = navigate cells from left to right (iii) Enter = submit pending changes (iv) Up/Down Arrows = navigate up and down between multiple order rows 2. When the FOB is launched, focus shall be set on the price cell of the first order, with the value highlighted and ready to accept modifications from the keyboard. If the price column is not included as one of the default FOB columns, then no cell shall have focus upon FOB launch. (Ref 198139)
01/29/2026			Improvements	FIX Services	A new FIX session parameter 'Send Tag 60 in Nanoseconds' is now available in the TT FIX Session Setup for Order Routing and Drop Copy sessions, allowing higher granularity in tag 60 (TransactTime). 1. This parameter applies to Tag 60 in all outgoing messages for FIX Order Routing, Recovery, and Drop Copy sessions and will be unchecked by default. 2. If checked, tag 60 will be sent in nanoseconds `YYYYMMDD-HH:MM:SS.sssuuunnn`. If nanosecond precision is enabled but the exchange does not support it, the timestamp will be padded with zeros to maintain the nanosecond format. 3. If unchecked, tag 60 will be sent in microseconds `YYYYMMDD-HH:MM:SS.sssuuu`. 4. If the TrimTimestamp rule is set in the session, it will always take precedence over this new parameter and tag 60 will be sent in miliseconds `YYYYMMDD-HH:MM:SS.sss` based on the rule criteria. (Ref 198107) Version: v295
01/23/2026			Improvements	Settings	Added a new "Enable Exception Management" setting to the FIX Order Routing session configuration in TT Setup. When enabled, most inbound FIX care orders with errors will no longer result in immediate client rejections. Instead, these orders will be processed and displayed in the TT front-end within a new "Order Exceptions" widget. This widget provides "Repair" or "Reject" options for direct management of these error orders. Note that front-end users must have OMS Advanced features enabled in Setup to access this functionality. See our documentation for more details. (Ref 198101)
01/22/2026			Improvements	Order Entry	Enhancement #1 Eurex and EEX are enhancing their SMP feature to add 3 new SMP types , in addition to the setting for Market wide and industry wide testing . These new SMP types will be available as a new drop down on TTUS , and the following values will be allowed :- 1. Cancel Incoming Order 2. Cancel Resting Order 3. Reduce Greater These SMP types can be set on TTUS user configurations , and also overridable through FIX Enhancement #2 Eurex suggests that “If the Client Identifier field is not provided for agent orders, then they will be rejected. For orders sent with TradingCapacity Proprietary or Market Making, the Client Identifier field may remain empty “ . To support this feature, TT is adding an enhancement to reject orders internally under the below condition :- * When the “Trading Capacity” is set to “Any other Capacity” for user , then if the order is sent with "Client ID" as blank , then the order will be rejected. (Ref 191545)

(These native orders are considered "grandchildren" of the care order because they are actually placed and managed by the algo.) The price and quantity modifications abide by all current care order restrictions such as not exceeding the parent care order quantity and not exceeding price (when price is restricted). (Ref 194194)
01/13/2026	01/27/2026	03/19/2026	Improvements	Order Book	In the Order Book and Orders and Fills widget (OFW), the button that appears in the "Release" column when fills are received on a locked care order now displays the quantity of fills that have not yet been released. For example, for a locked care order that has twenty (20) unreleased fills, the button label displays as "Release (20)". After clicking the button and releasing the fills, the button disappears and the cell displays "Released" as per current behavior. (Ref 194193)
