HTX WebSocket API
The HTX WebSocket API provides a two-way real-time channel for subscribing to market data (klines, market depth, trade detail, best bid/offer) and to authenticated account and order update topics. Public market data streams over wss://api.huobi.pro/ws and authenticated account/order streams over wss://api.huobi.pro/ws/v2, with heartbeat and rate-limit controls.
