WebSocket Streaming

WebSocket Streaming is a communication protocol that provides full-duplex, persistent connection channels between a client and a cryptocurrency exchange server. Unlike traditional REST API requests, which require the client to constantly poll for updates, WebSockets allow the server to push real-time data to the client as soon as a market event occurs.

This significantly reduces latency and resource overhead, making it the preferred method for streaming order book updates, trade history, and account balance changes. Because the connection stays open, traders can react to market movements in milliseconds, which is vital for competitive trading strategies.

However, maintaining these persistent connections requires robust error handling to manage drops and reconnections seamlessly. It is the backbone of modern, high-performance digital asset trading interfaces and automated execution engines.
