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

Interface Description

This interface supports batch subscription to the latest trade price of products (real-time tick-by-tick data, also the current price and latest price). It does not support historical trade prices (historical tick-by-tick data). For each WebSocket connection, every time this request is sent, the backend overwrites the previous subscription request by default. For example, if you initially subscribed to products A, B, and C, and want to add E, F, and G, you need to resend A, B, C, E, F, and G together. After the subscription succeeds, data will be pushed. Notes:

After a subscription succeeds once, you do not need to frequently initiate subscription requests again. You must send a heartbeat every 10 seconds, and the interface will push data in real time. If no heartbeat request is received within 30 seconds, it will be considered timed out and the requester’s WebSocket connection will be disconnected.
During integration, customers can add automatic reconnection logic to ensure the connection can automatically reconnect after disconnection caused by network or other reasons.
