Improvements

Trade Surveillance

Enhancements
Cross Trade Model (backup logic for TransactionID)
Currently, for whitelisted exchanges in the cross-trade model, we rely on the transaction IDs to score. We are introducing a new backup logic in the absence of transaction IDs. The backup logic is that if the Transaction ID codes don’t match the model will still capture the cross trades if it’s the same price and occurred in a < 1 millisecond time window.

Full list of Accounts and New Trader field in dropdown selection under Alerts
The account selection dropdown when setting alert conditions now displays the full list of available accounts. Additionally, the Trader ID field is now available as a condition for setting up alerts.

Updated Closing period for MIAX HRS Wheat

Ability to see multiple instruments in Audit Trail
Some of our newer models allow users to monitor across multiple instruments for the same product. This update allows users to see all the audit trail activity across these different instruments which was previously not available.

New Columns in DataLens
We have added algo_name and algo_id as two new columns in DataLens.

Improved visibility for IOP models
To improve visibility of influencing the Open and IOP Cross Models, we've enhanced the UI. Now, the IOP value is clearly visible at each order execution time. IOP changes are also added to the audit trail (highlighted in green) and charted as a line in the cluster chart, providing a clear visual of which order triggered a cross.
Bug Fixes
Fix for Review status not being updated on the Alert tab for the reviewed clusters. The Alerts tab now reflects the accurate review status for the cluster.

Fix for the issue where Datalens UI failed to retain saved column configuration after page reload
