Improvements

Trade Surveillance

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.
