WebSocket Streams

WebSocket streams provide a persistent, full-duplex communication channel between a client and an exchange server over a single TCP connection. This technology is essential for receiving real-time market data, such as price updates, order book changes, and trade executions.

Unlike traditional REST requests, WebSockets allow for low-latency data delivery without the overhead of repeated HTTP requests. This makes them ideal for high-frequency trading and real-time monitoring applications.

The persistent nature of the connection ensures that traders receive information as soon as it is available. WebSocket streams are widely used in digital asset exchanges for their efficiency and speed.

Implementing them requires careful management of connection state and data parsing. They are a critical component of modern, high-performance trading architectures.

The use of WebSockets enables traders to react quickly to market events.
