Automate your trading with OANDA’s REST API
Connect to our robust v20 trading engine. Use our API to build, test, and set up custom trading strategies and get programmatic access to OANDA’s pricing and execution.
How does OANDA’s API work?
Integrated market data
Get real-time rates for all tradeable pairs 24 hours a day, and access historical pricing information dating back to 2005. Our historical REST endpoints are highly customisable for pulling specific time bars (ranging from 5-second bars to monthly candlesticks).
WebSockets
We utilise stable, dedicated streaming sockets to separate real-time price delivery from order placement.
Streaming
Our architecture natively separates heavy data loads by streaming real-time ticks continuously rather than forcing developers to poll.
HTTP request/response cycle
This defines how we handle all transactional tasks (placing orders, modifying stops) reliably using standard JSON payloads.
Endpoint
Our developer portal provides highly distinct, well-isolated endpoints categorised clearly by function (Accounts, Orders, Trades, Pricing, Positions and Transactions).
Sandbox environments
Our API gives an excellent, completely unrestricted "FxTrade Practice" sandbox tier that exactly mirrors the production API endpoints for paper trading and backtesting.
Bid/Ask pricing fields
Our API passes full, independent Bid and Ask price objects across both REST and WebSocket feeds.
HTTP Persistent Connections (Keep-Alive)
The API servers actively support and require Keep-Alive configurations to minimise connection overhead.
Transaction system / TransactionID
The API relies on a highly rigorous, sequential transaction tracking engine (TransactionID) that makes state auditing incredibly stable.
Diff
Instead of downloading an entire portfolio block repeatedly, our transaction endpoint allows you to pass the last known transaction ID to fetch only the incremental changes ("diff") since your last call.
