Called when the websocket succesfully connects to the server. You might want to include some initialization here and do the subscriptions.

Called when the websocket disconnects. The lambda parameter indicates, whether the connection was closed on demand by user, or by some external factors, like connection problems. You might want to use this for auto-reconnect logic, if the connection was closed unexpectedly.

Callback called when any error occurred. For finnhub error responses you will get FinnhubException with the received message. For all other errors the original exception will be emitted.

Flow of all trades the client is subscribed to. Each list contains only items of single symbol. If there are subscriptions for multiple symbols, each will emit in separate lists, you have to distinguish them by TradeItem.s of any item in the list.
