Websocket Connectivity

Websocket connectivity provides a full-duplex communication channel over a single TCP connection, allowing for real-time, bidirectional data transfer between an exchange and a trader's application. Unlike REST APIs, which require the client to poll for updates, websockets push data to the client as soon as it becomes available.

This is essential for high-frequency trading and live market monitoring, as it drastically reduces the time between a price change and the trader's awareness. Websockets allow for instantaneous updates on order book changes, trade executions, and account balances.

Maintaining a stable websocket connection is a key technical challenge, as disconnects can lead to data gaps and missed opportunities. Robust systems implement automatic reconnection logic and heartbeats to ensure constant uptime.

It is the backbone of modern, reactive trading architectures. The speed and reliability of this connection directly impact the effectiveness of any real-time trading strategy.
