Release notes

View the history of B2PRIME API releases with key points and major updates highlighted

Improvements

Trading API: Stop orders for closed markets

The Trading API now accepts Stop orders for markets that are closed according to their trading calendar. 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.

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.

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.

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.

Added FIX API documentation

Added new FIX API section covering Market Data and Trading sessions via the FIX 4.4 protocol.

The publicAccountId field has been added to account-related API responses as a preview, ahead of the full rollout across all endpoints.

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.
