MEXC WebSocket API
Subscribe to MEXC spot WebSocket streams (deals, kline, depth, bookTicker, miniTicker) and authenticated account channels with HMAC signing.
Subscribe to MEXC spot WebSocket streams (deals, kline, depth, bookTicker, miniTicker) and authenticated account channels with HMAC signing.
MEXC spot WebSocket client — deals, kline, depth, bookTicker and miniTicker plus the listenKey-based private account stream.

MEXC v3 ships market data as Protobuf-encoded binary frames; the component decodes them and surfaces typed events.
SubscribeDeals, SubscribeDepth, SubscribeKLine, SubscribeBookTicker, SubscribeMiniTicker cover the spot public surface.
StartUserDataStream returns a listenKey; SubscribeListenKey opens the account-data WebSocket for balance / order / position updates.
MEXC sends ping frames; the component answers automatically. WatchDog re-subscribes after reconnect.
One TsgcWSAPI_MEXC instance can handle hundreds of symbols by chaining subscribe calls — routing is internal.
TsgcWSAPI_MEXC_Futures targets the MEXC futures contract gateway with the same component surface.
