Heartbeat

This page describes the heartbeat mechanism of AllTick’s stock WebSocket API, showing Ping-Pong message formats and how to keep connections alive, detect disconnects, and reconnect, so developers can maintain stable WebSocket streams for realtime tick and order book data.

Interface Description

The requester is required to send a heartbeat every 10 seconds. If no heartbeat request is received within 30 seconds, it will be considered timed out and the requester’s WebSocket connection will be disconnected.
