Set Kucoin.ApiKey / Kucoin.ApiSecret / Kucoin.ApiPassPhrase, pair with a TsgcWebSocketClient, and let the component perform the public/private token bootstrap.

KuCoin requires a one-shot REST call to obtain a connect-token and endpoint before opening the WebSocket. The component performs that step transparently before connecting.
SubscribeTicker, SubscribeSnapshot, SubscribeLevel2, SubscribeLevel3, SubscribeMatch, SubscribeCandles cover every spot public channel.
Authenticated streams (balance, orderChange, tradeOrder) open after the private connect-token flow — signed with ApiKey, ApiSecret and ApiPassPhrase.
Incremental updates over the L2/L3 channels let you reconstruct the full book locally — the component exposes both snapshot and delta events separately.
KuCoin uses application-layer ping/pong; the component answers automatically and tracks the interval the gateway negotiates at connect time.
TsgcWSAPI_Kucoin_Futures targets the futures contract gateway with the same patterns — one component class per product family.
