Pair the component with a TsgcWebSocketClient, set Cex.ApiKey / Cex.ApiSecret if you need private channels, then SubscribeTicker / SubscribeOrderBook / SubscribeTrade.

Cex->SubscribeOrderBook("BTC", "USD", 30);Public market streams plus authenticated trading endpoints — one component, two channel sets.
SubscribeTicker, SubscribeOrderBook and SubscribeTrade deliver public market data for the chosen currency pair without authentication.
Set Cex.ApiKey and Cex.ApiSecret — the component HMAC-signs the auth payload and unlocks the private trading channels.
PlaceOrder, CancelOrder, OrderBook snapshot, and OpenOrders calls reach the authenticated side of the same WebSocket connection.
OrderBook subscriptions deliver an initial snapshot followed by incremental updates — the component exposes both events separately so you can sync a local book.
On WatchDog reconnect the component re-subscribes to every previously active channel and replays the auth handshake transparently.
TsgcWSAPI_CexPlus targets the institutional CEX.IO Aggregator endpoint — same component surface with extended trading actions.
