Production 06/05/2026 Improvements General

For certain Butterfly spreads from ICE, the legs are not defined in chronological (expiry) order in the instrument definition message by ICE. As part of this change, the alias/display name for certain Butterfly spreads will be updated. Going forward, TT will always display the earliest-expiring leg in the alias for ICE, ICE_L Butterfly spreads.

For example, "Oct27 1mo Butterfly" will now be displayed as "G Aug27 1mo Butterfly", since the earliest-expiring leg is Aug27.

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Order Entry

We have refined the current “Seed blank account when selecting a profile” feature to better meet the needs of global firms to default a specific account per region. Specifically, in order entry widgets, when the global Preference > Orders > "Seed blank Account for profile without…" is enabled and an account is already selected, the currently selected account will now persist when a trader selects a new profile. The selected account will only be overridden and seeded with a new one if one of the following two conditions is met: (1) the new profile has only one account assigned to it in Setup (seed that account), or (2) the new profile has one matching local profile rule for the user and specifies an account on that local rule (seed that account). This revised logic will always apply when using the ”seed blank” preference with no need to opt in via another setting.

(Ref 205683)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Order Entry

The Order Ticket now offers enhanced price transparency when inputting an order quantity without a specific price. It displays the average price for the proposed order and, optionally, the minimum/maximum aggressive price. These values assist users in determining whether to populate the price field with the aggressive price before submission. The minimum/maximum aggressive price is derived from the total available market depth for the entered quantity.

Both the "Average Order Price" and the "Min/Max aggressive price" automatically recalculate and update with changing market conditions, even after a maximum aggressive price has been chosen. This feature is functional regardless of where the Order Ticket was opened from within the market depth and is available on exchanges without a native Market order type (e.g., EPEX and Nord Pool).

Production 06/05/2026 07/23/2026 05/05/2026 Fixes Orders

Fixed a timezone conversion issue affecting session start times for CME and MIC markets, which caused some orders from previous sessions to appear incorrectly.

(Ref 205374)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Market Data

The Product Grid now includes an optional "OpenInterest" column.

(Ref 205313)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Market Data

(Ref 205285)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Order Entry

Child orders of care orders can now only be placed and/or modified with Time-In-Force (TIFs) that expire sooner than or at the same time as the TIF of the care order. This ensures that the child orders will expire along with the parent care order, preventing them from remaining active in the market longer than the care order's duration and potentially causing unwanted fills.

(Ref 205284)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Order Entry

You can now paste text from the system clipboard into any price input control in the TT front-end application using the standard Ctrl+V keyboard shortcut. The application validates pasted content against the same rules and behaviors as manually typed input.

(Ref 205283)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Algo Dashboard

The Algo Dashboard (AD) now automatically selects algo orders when opened from the Order Book or Orders and Fills widget (OFW), reducing manual actions. The parameters pane will automatically appear, and parameter values common to the selected orders will be pre-populated, making it easier to adjust settings on multiple algo orders simultaneously.

(Ref 205281)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Fills

In the Orders and Fills widget (OFW) you can now assign and unassign "head" fills of multileg spread orders, e.g., the spread fill itself, to care orders. The associated leg fills will also be included as part of the assign/unassign action.

(Ref 205280)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Order Entry

You can now open multiple order tickets (OTs) simultaneously, configure the orders separately in each, and submit them all at once with a customizable hotkey. This can be useful when preparing for a major economic news release, or when working care orders on multi-leg instruments.

(Ref 205279)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Fills

In the Orders and Fills widget (OFW) you can now assign "synthetic" fills, e.g., fill records generated by TT algos, to care orders. Previously only the native fills could be assigned.

(Ref 205275)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Order Entry

The Order Ticket now allows you to manually resize the width of custom action buttons and order parameter drop-down controls by dragging with the left mouse button. After adjusting the size to your preference, you can save it as your default setting. As part of this work, the buy/sell leg information for multi-leg instruments (when using single button broker mode) has been relocated to the top of the Order Ticket to utilize the available width more effectively for long instrument names

(Ref 205221)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Order Entry

The Order Ticket has a new right click setting that resizes the ticket to display all parameters when loading an order type that requires additional parameters. This setting offers three choices: (1) "Minimal auto-expand" which behaves the same as the previous behavior when the "Retain Order Ticket fixed size (do not auto-expand)" setting was unchecked, (2)  "Fully auto-expand" which resizes the OT when an order is selected to display all associated parameters; and (3) "Retain saved fixed size" which behaves the same as the previous behavior when the "Retain Order Ticket fixed size (do not auto-expand)" setting was checked.

(Ref 205209)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Order Entry

The Order Ticket (OT) now allows instrument selection via the Market Explorer, accessible from the upper left corner. Details of the current instrument are displayed with dynamic links for quick edits. Selecting a new instrument from a different Exchange, Product, or Product Type will re-seed the OT, just as opening an entirely new OT with that new instrument would. Selecting a new instrument from the same Exchange, Product, and Product Type (e.g., a different month or strike price) will re-seed the OT, but retain the order quantity, type, profile, account, and other seeded information. The Market Explorer and instrument details can optionally be hidden via the right-click "Show/Hide" menu and saved as the default view.

(Ref 205200)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Order Entry

The Custom Action Button (CAB) configuration dialog now allows you to customize the background color and text label color of each CAB.

(Ref 205113)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Order Entry

You can now change the vertical display order of custom action buttons via left mouse drag-n-drop in their configuration dialog. Previously you could not change the order and had to redo all the buttons just to have a new button appear at the top.

(Ref 205112)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Order Entry

Custom Action Buttons now use the same proportional font as adjacent dropdown controls, replacing the previous fixed width font that did not match the rest of the nearby controls.

(Ref 205111)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Options

In Market Grid the list of options products related to a future that is displayed via the "Related Contracts…" feature now includes the expiration date and the name of the option product. Previously the list displayed as symbols only (without the exp date and description).

(Ref 205110)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Order Entry

The Order Ticket is now available from the main widget menu as an option in the "Order Management" section.

(Ref 205057)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Order Entry

The Order Ticket now includes an optional RFQ button that submits an RFQ for the current instrument when clicked. The button visibility can be managed via the "Show/Hide" right click menu.

(Ref 205056)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Orders

When you assign a spread fill on a care order, TT now also assigns the leg fills.

(Ref 205055)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Order Entry

We now restrict child orders of care orders to have a Time-in-Force (TIF) that will expire along with the parent care order. This prevents creating child orders that could potentially work in the market for longer than the time of the care order and cause unwanted fills.

(Ref 205053)

Production 06/05/2026 07/23/2026 05/05/2026 Fixes Order Book

Fixed an issue that sometimes prevented the FillQty on a care order to not be updated correctly in the Order Book or Orders and Fills widget (OFW).

(Ref 205051)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements MD Trader

We have disabled the Manual fill order type from MD Trader for care orders on multi-leg instruments because unlike the Order Ticket, MD Trader does not support specifying the leg fill prices.

(Ref 205050)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Orders

In the Orders and Fills widget (OFW) you can view the fills of an order by clicking the "eyeball" icon on the order row. We have improved this feature to view all the fills of a combined care order, e.g., bulked or stitched order, to provide an aggregated view of the fills of all the constituent care orders. Now, when you click the eyeball on a combined (bulked, stitched) care order and the order is fully or partially filled, the eyeballs of all the constituent care orders will also be selected and disabled by default, and will display the fills of the constituent care orders. To view the fills for an individual constituent order, you can unselect the eyeball of the combined care order and select the desired child care order.

(Ref 205049)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Fills

To properly identify fills that were executed outside of TT, we have added two new columns in the Order Book, Fills widget, OFW, Audit Trail and Audit Query widget: (1) "ExchExecID" – assigned by the exchange as a unique identifier for a fill, and (2) "TrdMatchID" – assigned by the exchange as an identifier of the match event of a trade.

(Ref 205048)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Positions

We have extended the current Position Manager widget feature that supports upload of local fills via csv files to also support csv upload of Admin Fills and SOD records. As part of this work we also support including exchange-facing IDs in the csv files to properly identify fills that were executed outside of TT. These fields are ClOrderID, ExchOrderID, ExchExecID and TrdMatchID.

(Ref 205047)

Production 06/05/2026 07/23/2026 05/05/2026 Fixes Strategy Creation

Fixed a leg ordering issue that prevented stitching two Eurex option care orders into a user-defined strategy.

(Ref 205045)

Production 06/05/2026 07/23/2026 05/05/2026 Fixes Order Book

Fixed an issue when using the right click "Edit Order" functionality in the Order Book, with "Enable broker mode" setting set in the Order Ticket, submitting the change request submitted using the <Enter> button on your keyboard caused a new order to be placed, instead of updating the existing order.

(Ref 205043)

Production 06/05/2026 07/23/2026 05/05/2026 Improvements Fills

The current method to allocate a filled order in the Allocation pane of the Orders and Fills widget (OFW) is a multi-step process requiring numerous clicks. To simplify this, cells in the "Allocated" column of the OFW on fully filled order rows now display a button labeled "Allocate". This button enables only when a single fully filled row is selected and one or more routing rules have been defined. Left-clicking the button presents a drop-down list of user-configured routing rules. Select a routing rule, click "OK", and the fill will be allocated according to the chosen Routing Rule.

(Ref 205041)

Production 06/05/2026 05/04/2026 Improvements FIX Services

Euronext has added support for instrument Series Term of Half Year on their API messages. Correspondingly, TT has introduced a new value to tag 18211 (DeliveryTerm) and 18212 (LegDeliveryTerm) in the Instrument and the Instrument leg components in the FIX messages in Drop copy, Order Routing and market data sessions.
1. Z:Half Year
