@cloud9trader/oanda-adapter

Node.js adapter for OANDA's v20 REST and streaming API, from Cloud9Trader.

• Provides a single interface for requesting data and streaming prices and account updates.

• Smooths over polling and streaming endpoints for account updates and pricing for consistent subscriber methods.

• Handles streaming connection loss and heartbeat timeout and retires connection.

• Manages multiple price subscriptions and changes to the subscribed instrument list over a single long polling request.

• Rate limits REST requests according to OANDA limit with automatic queuing for delayed execution and warning logs.

• Returns instances from OANDA's definitions library at https://github.com/oanda/v20-javascript for editor code hinting and content assist.

• OANDA endpoints return data specific to your account. Retrieves default account ID so client does not need to specify.

See also OANDA's v20 REST API documentation for reference.

API Compatibility

This is compatible with OANDA's v20 APIs. If your account ID contains only digits (eg. 2534253), you have a v1 account - please use version 1.0.0 of this module.
