Release notes

Releases summary

Bug fixes

• We have fixed an issue in the Failover configuration UI where 24:00 could not be selected as the end of a time window. Users can now configure failover periods that span the full day (e.g., 00:00–24:00) by selecting the new End of day option on the To time picker, matching the behaviour supported by the Matching Engine API. The minimum Failover Timeout value has also been corrected to 1 second, aligning with the Matching Engine API requirement.

Bug fixes

• We have fixed a bug in streaming mode where the data grid could show an incorrect time range when calculating the streaming period, potentially leading to missed or duplicated rows.
• We have added advanced group filtering with wildcard support for Volume reports. Users can now filter by exact group names or use wildcards (*) to match multiple groups. Supports both inclusion and exclusion filters (e.g., live*, !demo*). Fixed critical bugs with filter combination logic and SQL query performance.
• We have fixed an issue where the Conversion Rate to USD and Conversion Rate to EUR columns in the Trade Blotter were displaying 0 for symbols with fewer than 5 decimal places.

What's new

• Close Bid/Ask (previous trading day last price) — Previous trading day closing prices (Bid Close and Ask Close) are now streamed via the WebSocket API, enabling clients to display daily change indicators. Values are persisted so they survive restarts.

Bug fixes

• Group markups on floating P/L — Group markups are now applied to floating (unrealised) profit/loss calculations, ensuring that unrealised P/L reflects the correct marked-up prices.
•  SL/TP double-trigger prevention — Fixed a race condition where Stop Loss and Take Profit service orders could trigger twice. The execution lifecycle for service orders has been corrected.
•  Group/client deletion with linked accounts — Fixed a bug that allowed deletion of groups or clients that still had linked trading accounts. The server now returns a "dependencies exist" error instead.
• Minor bug fixes and improvements

Misc

• API error codes documentation — Standardised error code enum (ApiErrorCode) added across all API specifications (REST and WebSocket). Updated password field requirements for trading account creation and group field clarifications.
•  3rd party dependencies have been updated to the latest versions
