Create a websocket infrastructure by implementing a connection proxy and a ws connection proxy with start, stop, send, on connect, on receive, on error, on close, and automatic reconnect.
Implement a trades channel subscription for a selected currency pair and unsubscribe others. Avoid race conditions with promises and timeouts; update the Redux Toolkit builder to include trades.
Learn to acknowledge subscriptions in the transport slice with subscribeToChannelAck, building a dynamic, id-keyed subscription map from channel and symbol data (trades and candles).
Add ticker handlers and a reducer to process real-time websocket data, including subscriptions and heartbeats. Wire a ticker slice that stores symbol and data and dispatches updates.
