WebSocket Heartbeats

WebSocket Heartbeats are periodic signals sent between the client and the server to maintain an active connection and detect if the connection has been dropped. If a heartbeat is not received within a specified time, the system assumes the connection is broken and initiates a reconnection.

This is vital for persistent WebSocket streams, as it ensures that the trader is always aware of the connection status and can react to disconnections immediately. Without heartbeats, a silent disconnection could lead to a loss of critical market data, which could be catastrophic for an automated trading strategy.
