Release Notes

15.3.0
Enhancements
Model Snapshot Storage for On-the-Fly Scheduler Updates: Model snapshots are now stored in the database, allowing the report scheduler to be updated at runtime without requiring a redeployment.
Deal Time Model – Reported Transaction Legs: Legs of reported transactions are now included in the Deal Time model, improving detection accuracy for related order activity.
Influencing the Open Model – Stop Order Exclusion: Stop orders are now excluded from the Influencing the Open model, reducing false positives caused by non-aggressive order types.
Aggressor and Manual Indicator in Ledger Data: The system now accurately determines whether the aggressor indicator and manual indicator are present in ledger data, improving data quality for downstream models.
Pre-configured Comments in Bulk Updates: Users can now select from pre-configured comment templates when performing bulk updates, improving consistency and efficiency in cluster processing workflows.
Apply/Reset Controls for Column Search & Time Formatting: A unified Apply/Reset control has been added to column search filters, and time column formatting has been corrected for consistency across the surveillance views.
Active Row Highlighting on Quick View: The active table row is now visually highlighted when the Quick View panel is toggled, making it easier to track which cluster is being previewed.
Improved Selection Handling with Global Selection: Shortcut selections are now properly disabled when a global (Select All Across Pages) selection is active, preventing conflicting selection states.
Wider Model Filter Dialog: The Model Filter dialog on the Surveillance page has been widened to better accommodate model names and improve readability.
Dataviewer Instruments Filtering: The Dataviewer instruments endpoint now returns only instruments from the processed folder, ensuring users see accurate and relevant instrument data.
Deselect Clusters After "Select All" in Case Details: Users can now properly deselect individual clusters after using "Select All" in the Associated Clusters tab within Case Details.

Request IDs are now included in all Score API calls from the UI, improving traceability for support and debugging

You can now upload Routing Rules via CSV files, similar to the process for uploading Order Profiles.

(Ref 205366)

The TT front end application now reads and adheres to the company-level Soft Limits preference in Setup.

(Ref 205371)

We have added the ability to pause and resume FX Bank Algos.

(Ref 205377)

Added support within the Product Grid for the ability to seed the BidQtyAccum and AskQtyAccum values to the Order Ticket. Note, users with existing Product Grid widgets will need to populate a new one to be able to seed these values.

(Ref 205408)

We have modified the fill reporting when a locked care order has fills at multiple prices. Releasing the fills now defaults to reporting a single fill with the average price of those fills. Previously our release function released all of the individual fills separately. As part of this change, the Order Book toolbar Release button is now a two-function button, similar to the Bulk and Stitch buttons. The main button displays “Release”, and when clicked, reports one fill with the average price of the unreleased fills. The dropdown displays “Release Fills" and operates as before, releasing all of the unreleased fills on the care order individually.

(Ref 210092)

When creating a manual fill on a care spread order, the leg price seeding waterfall logic can sometimes fail, resulting in one leg being seeded with a blank price of zero (0). The end result is an error or at worst, the creation of a zero (0) leg price that deviates significantly from actual prices. To improve this, we now highlight leg input prices of zero (0) with a red, invalid background color. If the highlight warning is ignored, submitting that manual fill returns an error.

(Ref 210094)

In the Position Manager widget, when creating an Admin Fill on an exchange listed spread (ETS) instrument, we now ensure that leg manual fills are always created along with the spread (head) manual fill. To ensure this, when the instrument is an ETS, the “Create leg fills” checkbox is automatically checked ON and prevented from being unchecked.

(Ref 210095)

By default, the Order Book sorts records by fill time, but includes logic to group order types and status types in a specific order. For example, working orders are always sorted to the top, with care orders at the very top. Both of these are above filled orders, and held and stopped orders are sorted to the bottom. Some customers have requested to sort the records directly on the time column without any TT applied overrides. To provide this, a new "Ignore TT sorting by status" checkbox is now available in the Order Book and OFW settings. When enabled, sorting on a time-based column (Time, OrigTime, ExchTime, Date, OrigDate, ExchDate) bypasses TT's logic for a purely chronological sort result.

(Ref 210097)

The Orders and Fills widget (OFW) tabs are now independent of each other regarding columns, order/fills/position pane heights, etc. Included in these changes are fixes to overall OFW widget resizing issues.

(Ref 210132)

You can now drag the instrument currently seeded in the Order Ticket and drop into other grid widgets, such as Market Grid, MD Trader, Chart, Strategy Creation, etc.

(Ref 210133)

When the originator of a care order requests a modification to the order, the notification popup dialog now includes a button to "Approve and apply changes to child orders". Previously selecting this combination of approval and application was only available via the right click context menu on the care order.

(Ref 210136)

You can now close multiple care order notification popups all at once by holding down the ALT key while left-clicking on the "X". Previously you had to close them individually. Also, as part of this change, you can apply the same action (e.g., Claim, Reject, Execute) to multiple care notification popups while holding down the ALT key.

(Ref 210138)

The allocation percentages and portion sizes now support up to ten (10) decimal digits of precision.

(Ref 210143)

Routing Rules now allows defining non-integer portions, supporting decimal inputs up to ten (10) decimal places, and derives percentages from these portion values.

(Ref 210144)

Fixed an issue that prevented resizing technical indicator panels in charts.

(Ref 210146)

Care order notification popups can now only be closed by either clicking on the "X" or selecting a button action. Previously clicking anywhere in the notification background would close the popup.

(Ref 210147)

Fixed an issue that sometimes prevented modifying a care order from Limit to Market.

(Ref 210148)

The Order Book toolbar "Combine" button now functions as a toggle that opens and closes the adjacent Combine panel.

(Ref 210149)

Fixed an issue that prevented the "Company" parameter from being included in a risk request update when a new account is added to a user.

(Ref 210161)

Fixed an issue that prevented properly supporting Euronext evening sessions.

(Ref 210162)

Fixed an issue that sometimes caused the Product Grid to incorrectly display positions.

(Ref 210211)

The Depth widget now supports modifying working orders using the Floating Order Book (FOB) via new WrkBuys and WrkSells columns.

(Ref 210212)

You can now navigate multiple order rows in the Floating Order Book (FOB) using the up and down arrow keys by enabling a new global Preferences > Orders > Floating Order Book (FOB) checkbox named “Use Up/Down arrow keys to navigate orders”.

(Ref 210234)

Fixed incorrect Strategy Creation issues within Option Chain (New).

(Ref 210238)

Fixed an issue that prevented a Position In Queue value of zero (0) from displaying correctly in the Order Book and Floating Order Book (FOB).

(Ref 210239)

Fixed an issue that caused the "Conditional" algo to not correctly populate the "algo_name" in user params.

(Ref 210242)

Fixed an issue that sometimes caused the Positions widget to display an incorrect P/L Open value.

(Ref 210244)

Fixed an issue where the Options Chain (New) widget incorrectly displayed an “expired instrument” error message when the option’s underlying instrument expires before the options themselves.

(Ref 210251)

Fixed an issue where editing an Autospreader configuration reverts the account and quantity fields to defaults.

(Ref 210253)

Fixed an issue that prevented the Order Book from displaying an order from a previous session.

(Ref 210254)

You can now select your style of floating order entry widget on-the-fly via a new global Preference on the Orders page named "Select on click". With this preference set, when you click a bid/ask price or quantity in Market Grid or Market Depth, or click the B/S button on a care order in the Order Book to enter a child order, a menu will appear allowing you to choose to use either MD Trader or Order Ticket.

(Ref 210373)

The Depth widget supports the setting "View my orders only". Sets whether or not to hide orders from other traders sharing an account.

(Ref 204625)

The Product Grid and Depth Widget now have the same color settings that are available in the Market Grid.

(Ref 205383)

In order routing widgets, the order quantity field now supports using a comma instead of a decimal point as the integer decimal point separator. This setting can be configured on the global Preferences > General page.

(Ref 205388)

In the Market Grid and Product Grid, when depth rows are expanded, the "Last" and "LastQty" columns now display up to the ten (10) most recent traded prices and quantities in sequential order (most recent on top), immediately below the current Last and LastQty values. The values update in real time as new trades arrive, and historical values populate when the instrument subscription is established. This helps traders understand recent trading activity and gauge trend direction.

(Ref 212832)

Fixed an issue where "Only Allow Price Improvements on Child Orders" settings were inconsistently applied when the execution trader and order originator had different configurations. This update ensures uniform restriction enforcement across the platform, preventing unauthorized price handling and improving order submission reliability.

(Ref 213184)

The Instrument Search menu now displays the bonds icon for all TTFI Fixed Income product types (GOVT, CORP, SECPRO, MMKT, and MUNI).

(Ref 213347)

The Product Grid widget title now displays the number of products currently loaded, e.g., "Product Grid (3)", so you can see at a glance how many products a widget contains. When the widget has multiple tabs, the title reflects the product count for the active tab only.

(Ref 213475)

Time and Sales now includes an optional "Side" column that displays the aggressor side of each trade: "B" for a buy (blue), "S" for a sell (red), or blank when none (black). The Side value is also included in data exported from the Time and Sales widget.

(Ref 213476)

Blocktrader now includes a "Swap Clearer" field, located beneath the Open/Close dropdown, for Eurex EFS orders. This lets you specify how the swap leg is cleared: Eurex Clearing or Non-Eurex Clearing. The field defaults to Eurex Clearing, so orders submitted without changing it are cleared as they are today.

(Ref 213479)

In the Market Grid widget , LME TAS contracts now appear immediately below their related rolling contracts (CASH, TOM, 3M) rather than elsewhere in the grid. For example, NIDF 3M TC now displays directly beneath NIDF 3M. This applies to all current and future LME TAS contracts (e.g., AHDF, ZSDF, CADF, PBDF, SNDF, NIDF).

(Ref 213481)

The Order Book and Orders and Fills widget (OFW) now include an optional grouping panel alongside the left side of the widget. This panel lets you organize Order Book records into a nested, grouped hierarchy based on the fields you choose, making it easier to navigate and manage large numbers of orders. Click any group in the tree to view and organize the orders for that group. The panel is hidden by default; you can enable it via the widget's show/hide option. Groups are created and defined using a new "Grouping Manager" widget that is available from the main Edit menu. See our documentation for more details.

(Ref 213543)

The Product Grid widget now has a new color setting to highlight orders received via FIX messages.

(Ref 213575)
