Latest Trade Price (Real-time Tick Data) Batch Subscription

English / 中文

Interface Description

This API supports batch subscription to real-time trade prices (tick-by-tick data、Latest Price) but does not provide historical trade prices.

Each WebSocket connection allows one active subscription at a time. Sending a new subscription request overwrites the previous one. Example: If you initially subscribe to A, B, C and want to add E, F, G, you must resend A, B, C, E, F, G in a single request. Once subscribed, real-time data will be pushed automatically.

Important Notes： 1、Do not repeatedly send subscription requests. After a successful subscription, send a heartbeat every 10 seconds. If no heartbeat is received for 30 seconds, the server will assume a timeout and disconnect the WebSocket. 2、Implement automatic reconnection. To handle network disconnections, clients should implement an auto-reconnect mechanism.
