Release notes

Releases summary

What's new

• We have added automatic recovery for market-data subscriptions in the Liquidity Manager: when a liquidity provider rejects a symbol subscription, the LM now resubscribes automatically using a configurable exponential backoff, instead
  of leaving that symbol without quotes until the next full session reconnect.
• We have added a new FXPrimus market-data (quotes) connector to the Liquidity Manager.

Bug fixes

• We have fixed a Liquidity Manager bug where a Trade session would refuse to connect if the ApiData_<N>_NewOrderSingleTag (or sibling GroupTag / HeaderTag / TimeInForce) parameter exceeded 1024 characters — for example on configurations with many trading groups. The session now loads parameters of any length.

Misc

• Minor logging changes

---

Bug fixes

• We have fixed an issue where, after a temporary floating-leverage margin rule expired, an affected position's margin could stay elevated — or even increase — instead of returning to its normal level. Margin now correctly reverts to
  the original rate when the rule's interval ends

---

What's new

• Release notes subscriptions are now managed in the Cloud. New users are subscribed automatically, you can opt out any time from Account → Settings, a Release Notes link is now in the top navigation, and every release notes email includes a one-click unsubscribe link.

• We have fixed an issue where dynamic (floating) leverage on MT4 could repeatedly increase the margin charged on an account even when its positions and exposure were unchanged, causing accounts to be over-charged margin that grew over
  time.

What's new

• We have added a new Total Profit (USD) column to the WinRate report. In addition to the existing total profit shown in the account currency, the report now also displays the cumulative profit converted to USD using the per-trade conversion rate captured at execution time. The new column is available in both the UI grid and the CSV/XLSX export.

Bug fixes

• We have fixed an issue where exported report files ignored the selected sort direction and always produced ascending-order output. Affected reports: Cappitech, Swaps, Daily Report, Trade Execution, and Maker Historical Position.

What's new

• Symbol margin parameters in Get Symbol — The public Get Symbol endpoint now returns each symbol's full margin configuration: margin and profit calculation modes, per-lot initial and maintenance margin, and the complete matrix of initial and maintenance margin rates by order type and side.
• Server timezone in health check — The health-check endpoint now reports the server's configured IANA timezone (e.g. Europe/Helsinki) alongside the current time and version. 
• Exchange-mode margin engine (WIP) — Continued the per-symbol margin build-out, adding a symbol-type-agnostic margin seam and Exchange exposure handling for order modifications, and began migrating OTC margin onto the same engine.

Bug fixes

• Trade History now reports the correct position price for partially filled orders. 
• Minor bug fixes and improvements.

What's new

• Percentage inputs added for commission and margin fields across Symbols, Groups, Commission Tiers, and Order Routing Rules - values are entered and displayed as percentages, with the decimal equivalent sent to the API automatically.
• The Groups page now shows an Id column in the table. The Group Overview drawer's Common tab also displays the group Id as a read-only field.

• The Symbols Sessions tab now supports bulk editing, select multiple weekdays and apply the same quote/trade session schedule to all of them at once. The "Enable Separate Trading Sessions" checkbox has been replaced with a "Copy Quote Sessions" button.

  
  

• A new Eligible for currency conversion checkbox has been added to the Symbol Currency tab. MT5 import automatically sets this flag for known FX pairs.

  

• The Margin Calculation Mode and Profit Calculation Mode dropdowns in the symbol editor now show a short formula hint beneath each option while the list is open.

  

• ExchangeStocks and ExchangeBonds are now available as margin calculation modes. When either is selected, the Price Corridor Threshold field becomes required.

  

Bug fixes

• Stop Loss and Take Profit fields no longer auto-fill with the current bid price on focus, they now start empty and require manual input.
• Order routing integer-only filter fields (By Spread, By Position Age, By Time Since Position Update, By Market Price Deviation) now correctly reject decimal values with a validation error.
• Quick search on the Managers and Trading Accounts pages now correctly filters server-side data.
• Pagination on large datasets no longer causes an infinite "Invalid nextToken" loop. The UI silently recovers on a stale cursor and only shows a retry prompt if the recovery also fails.
• Symbols with CFDINDEX or CFDLEVERAGE calculation modes now import correctly from MT5 — these modes previously caused the import to fail.
• Special characters (&, <, >, quotes) in free-text fields (symbol description, commission profile description, holiday description, trading account comment, client comment) are now stored and displayed correctly without HTML entities leaking into the UI.

Misc

• Versions 26.6.1-26.6.3 are also included in this release.

What's new

• We have introduced Virtual Groups — a new configuration concept that allows grouping individual accounts and native MT group patterns into named collections (e.g., @@VG_PREMIUM). Virtual Groups can be used in all existing group pattern fields across execution delay, hedging multiplier, slippage absorption, included/excluded groups, manual hedging, and virtual liquidity pool configurations, enabling flexible account targeting without restructuring native MT groups.
•  We have introduced an optional per-symbol setting that, when enabled, aggregates a partially-filled order's individual fills into a single volume-weighted execution before notifying the trading platform, instead of sending one notification per partial fill. 

Bug fixes

• We have also corrected the applied-markup calculation so it is accurate for orders filled in fractional-lot pieces.

---

Misc

• Internal release, no new functionality

---

Bug fixes

We have fixed 2regressions in the MT5 ExternalOrderListener plugin:

   - the build version is once again reported correctly in the startup log;

   - the Use32BitSettlementDate setting is now preserved across plugin restarts 

---

Misc

• We have made internal release (sending extra information to Gateway)

---

What's new

• We have added an opt-in performance diagnostics parameter to the MT5 DataWarehouse plugin that logs per-hook latency on demand, helping diagnose throughput issues without impacting normal operation when disabled.

---

Misc

• We have added performance monitoring feature to the plugin

---

Misc

• Saving artifacts to help with crash investigations
