SubscribeKLine, SubscribeDepth, SubscribeTradeDetail, SubscribeMarketDetail, SubscribeMarketOverview, SubscribeBBO cover the spot market surface.
Huobi compresses every WebSocket frame with gzip — the component decompresses on the way in and answers ping frames on the way out automatically.
v2-auth handshake with HMAC signing exposes accounts.update#v2, orders#$symbol and trade.clearing#$symbol private channels.
The TsgcWSAPI_HTX sibling is the same component re-exported under the new HTX brand — pick whichever name matches your codebase.
Point the underlying TsgcWebSocketClient at api.huobi.pro or api.huobi.com depending on your jurisdiction — the protocol is identical.
Huobi sends {"ping":...} at the application layer — the component answers each automatically so the connection stays open through proxies.
