Maintaining and Authenticating Deribit WebSocket Trading Connections
Summary
The tutorial explains how to use Deribit’s JSON-RPC WebSocket interface for streaming market data and sending exchange requests. It walks through creating API credentials, connecting from Python, and using a test environment before considering live trading. It advises limiting API permissions to those needed and protecting credentials, since authenticated access can enable account actions.
The connection flow establishes a heartbeat, responds to exchange heartbeat messages, authenticates with a client ID and secret, and refreshes authentication using a token. Once connected, a client can subscribe to trade channels for real-time updates, unsubscribe when needed, and send authenticated requests such as orders. The guide contrasts this event-driven stream with repeated REST requests and suggests applications including order book summaries, price alerts, balance monitoring, and automated orders. The document explains concepts and gives implementation guidance, but its example is explicitly illustrative; it provides no performance or reliability measurements and cautions that code errors can have consequences.
Key ideas
- WebSocket subscriptions deliver trade and other market updates as they occur.
- A persistent connection requires heartbeat setup and responses to server heartbeat messages.
- Authentication uses API credentials and can be refreshed with a token.
- Authenticated WebSocket connections can send trading requests as well as receive data.
- Testing on the exchange’s test environment and restricting API permissions reduce operational risk.
