Release Notes

TT will no longer provide or update the stunnel.zip file which customers had previously used to perform certificate pinning. The final certificate in the stunnel.zip file will expire on Oct 17, 2026.

Clients who previously download the stunnel.zip file from https://library.tradingtechnologies.com/tt-fix/general/stunnel.zip should migrate to their local machine’s certificate trust store as soon as possible. Digicert and AWS are both established Certificate Authorities and are available in the trust stores of modern operating systems.

Migration & Rollout Schedule:
1. September 22 (UAT): AWS trust store support is enabled in UAT. Clients connecting to UAT should ensure AWS is trusted within their certificate store.
2. September 23 -24 (Prod Sim): Staggered prod-sim rollout begins September 23 and completes on September 24.
3. September 25 – October 2 (Production): A 2-day staggered production deployment begins on September 25 in the NY data center, followed by a rollout to all remaining data centers completing on October 2.

Upon the deployment of the change to each environment, the Digicert certificate will be replaced with an AWS certificate, which is not included in the stunnel.zip. All impacted clients must add AWS to the local trust store.

For detailed configuration settings and OS-specific paths please refer the weekly TT System Admin News and Updates email newsletter here: [https://www.tradingtechnologies.com/support-updates/]

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)

15.4.0

Enhancements

Company Preferences Visibility Controls
Added controls under Company Preferences allowing firms to show or hide unused UI elements such as Classifications and specific Case and Cluster statuses across all UI pages.

Market Depth Chart Improvements (Insider Trading)
Eliminated blank data point gaps on non-trading days and weekends, and extended chart display up to the news trigger date for complete visual correlation.

Stop Limit Order Trigger Conversions
Stop Limit order trigger conversions (Triggered/Activated ExecType) are now treated as Modifies instead of New Single Orders, preventing stale ladder orders from being processed incorrectly.

RecordsSummaryStatsReports Performance
Optimised loading times and cache management for admin summary reports, backed by a DynamoDB companyId-subkey index.

Bug Fixes
User Preferences Reset Fix
Fixed an issue where Reset to Defaults was mutating the default user preferences object by reference, causing subsequent resets to retain previously edited values.

Date Range Picker Hour Drift
Fixed a UTC/local moment conversion offset drift in the Surveillance Cluster Filters dialog that occurred when reopening the date/time picker.

Aggressor Indicator Defaulting
Fixed an issue where missing Aggressor Indicator values from WFE were defaulting to false. These now correctly render as empty.

Collusive Spoofing False Positives
Refined Spoofing and Collusive Spoofing detection logic to ignore exchange-automated cancellations executed immediately after market close, reducing false-positive alerts.

GTC Dominance at Open False Positives
Resolved false-positive Dominance at Open alerts triggered by Good Till Cancelled orders that had been resting in the book for two or more days prior to market open.
