For using websocket:

1. Create Callback implements WebSocketCallback that would process messages, like trade.wayruha.mexc.ws.PublicWSConnectionTest.Callback
2. Define config MexcConfig conf = new MexcConfig("apiKey", "apiSecret"); ApiClient apiClient = new ApiClient(conf); WSClientFactory factory = new WSClientFactory(apiClient);
3. Define properties and socket itself Set<String> symbols = Set.of("BTCUSDT", "ETHUSDT") WebSocketClient ws = factory.orderBookSubscription(symbols, TopLimit.TOP10, callback);
4. Enjoy the flow
