The order is stored and activates automatically when the market reopens, instead of being rejected at submission. ### Reports API: full account history Trading reports can now be generated for the entire account history. The previous **92-day** limit has been removed, and an **All data** range is now available for report generation. ### Trading API: market asset identifiers The `baseAssetId` and `quoteAssetId` fields have been added to the v6 `/markets` responses, allowing clients to resolve the base and quote assets of each market without additional lookups. ### Accurate unrealized PnL Unrealized PnL returned by the API is now calculated using the correct order book side for each position direction, improving the accuracy of PnL values in position and margin responses. *** ## Resolved issues * Resolved an issue where `WebhookAlert` order reason and position modifier values were returned as numeric codes instead of API enum strings in History API `/v2/orders` responses. {% endupdate %} {% update date="2026-04-09" %} ## New features ### Trading credit in API responses Broker-issued **trading credit** is now exposed through the API. The account margin data response and the real-time margin stream include the current credit amount in the Reference Asset (`creditInRAT`). Credit is included in the account equity and excluded from the withdrawable amount. *** ## Improvements ### Webhook Trading API: webhook URL in key listing The list webhook API keys response now includes the `webhookUrl` field, so the configured webhook endpoint can be retrieved for each key. {% endupdate %} {% update date="2026-03-16" %} ## New features ### Webhook Trading API A new **Webhook Trading API** has been added, enabling automated order creation via webhook alerts with API key authentication. **Key points:** * Create and manage webhook API keys for secure authentication * Receive trading alerts and create orders automatically * Idempotency supported via deduplication ID * Market type routing by symbol prefix (spot, CFD, perpetual) ### Public Account ID A new `publicAccountId` field has been added across all API endpoints, providing a human-readable account identifier as an alternative to internal UUIDs. **Affected APIs:** * Trading API — account-related responses and filters * Settings API — account configuration endpoints * History API — all REST endpoints and WebSocket streams * Reports API — report responses and filters ### Long-term trading data history Date range restrictions have been removed from **Order History** and **Closed Positions** endpoints, allowing access to full trading history without time-based limitations. *** ## Improvements ### Transfer subtype field A new `subtype` field has been added to transfer responses in the History API to distinguish **Negative Balance Protection** transfers from manual ones. ### Rounded position prices The `positionPriceInRAT` values are now properly rounded in closed position API responses according to the Reference Asset (RAT) scale. *** ## Resolved issues * Resolved an issue where `/total-swaps` requests returned HTTP 504 timeout errors. {% endupdate %} {% update date="2026-03-11" %} ## Added FIX API documentation Added new FIX API section covering Market Data and Trading sessions via the FIX 4.4 protocol. {% endupdate %} {% update date="2026-03-11" %} ## Initial version {% endupdate %} {% update date="2026-03-02" %} ## New features ### Trading Terminal AI assistant A new **AI assistant** has been added to the Trading Terminal, providing traders with an intelligent widget for market analysis and trading support. *** ## Improvements ### Public Account ID (preview) The `publicAccountId` field has been added to account-related API responses as a preview, ahead of the full rollout across all endpoints. {% endupdate %} {% update date="2026-02-25" %} ## New features ### Funding Rates API New API endpoints have been added for retrieving funding rate data synchronized from **B2CONNECT**, including funding rates, mark price, and funding interval for Perpetual Futures markets. **Key points:** * Funding rate values streamed in real time * Mark price used for position valuation when available from LP * Funding interval synchronized per market configuration * FIX API contract extended with funding data fields ### OHLC Candlestick API A new API endpoint has been added for retrieving OHLC (candlestick) data, supporting both **Spot** and **Perpetual Futures** markets. Minute-level candle data is now stored for up to 5 years. OHLC candle data streaming is also available via the WebSocket API using gRPC transport, providing real-time candlestick updates. ### Favorite markets A new **Favorite markets** feature has been added, allowing traders to manage personalized market lists via the Trading API. ### Comment field for orders and positions A new `comment` field has been added to order and position responses across REST, WebSocket, and History APIs. The comment can be set when placing an order and is propagated to the associated position and execution records. ### B2COPY Integration API New API endpoints have been added for **B2COPY** and IB (Introducing Broker) integrations, including special account types for copy trading. The `isCopyTradingAccount` field has been added to the `/api/v1/total-fundings` endpoint. *** ## Improvements ### FIX API: enhanced request throughput The FIX API trading request processing has been optimized to support up to 100 requests per second per connection. All `TimeInForce` types are now supported, including **GTD** (Good Till Date). ### Multilingual support Trading API, Settings API, and Reports API endpoints now support multilingual content with full Unicode character support, enabling localized responses for configurable fields, report names, and templates. ### Stop Market order calculation The **Value** and **Amount** calculation for **Stop Market** orders has been corrected for **Spot** markets. **Slippage Rate** has been removed from **CFD** and **Perpetual Futures** order calculations. ### Trading API: empty categories hidden Empty market categories are now automatically excluded from Trading API responses, reducing unnecessary data in category listings. ### Balance API: zero balance for all assets Assets without prior balance operations now return a zero balance in API responses instead of being omitted. ### Cross-rate market configuration Markets used exclusively for cross-rate calculations can now be disabled for trading while remaining active for rate conversion. ### History API: extended contracts Positions and Events API responses have been extended with additional fields. The `updatedAt` field is now available as a sorting and filtering parameter in History Server API endpoints. ### Settings API: market update endpoint The market update endpoint has been changed from `PATCH` to `PUT` semantics, requiring the full market object in the request body. ### Settings API: legacy endpoints removed Legacy commission and routing rule endpoints have been removed following the tier commission update. Use the current endpoints as documented in the API reference. *** ## Resolved issues * Resolved an issue where `takeProfitPrice` and `stopLossPrice` values were missing from the History Server `/v2/orders` endpoint responses. * Resolved an issue where bulk order cancellation returned a successful result for non-existing orders. * Resolved an issue where bulk order cancellation returned a successful result for orders that could not be cancelled. * Resolved incorrect error codes returned when `closePositionLotAmount` was set to `0`, a negative value, or an empty string. * Resolved an issue where the WebSocket Book stream continued sending prices with an outdated tick size after market parameter changes. * Resolved an issue where negative spreads in the **Market Data API** were not handled correctly. * Resolved an issue where orders could not be created when using the default 24/7 calendar. * Resolved an issue where the `/external-orders` API returned `null` for `rejectReason` although the Trading Server received a reason from the LP. {% endupdate %} {% endupdates %} --- # Agent Instructions This documentation is published with GitBook.
