reference: https://binance-docs.github.io/apidocs/voptions/en/#websocket-market-streams streamName: you should collaborate stream names through official documentation or other function above defined, the legitimacy of parameters needs to be guaranteed by the caller handler: a map of handler function, its key needs to correspond to the handler of the incoming streamname, handler's key should be in ["trade", "index", "markPrice", "kline", "ticker", "openInterest", "option_pair", "depth"] for example: WsCombinedServe({"ETH-240927-5500-P@depth10"}, map[string]interface{}{"depth": func(*WsDepthEvent) {}}, func(error){}) WsCombinedServe({"ETH-240927-5500-P@depth10", "ETH-240927-5500-P@kline_1m"}, map[string]interface{}{"depth": func(*WsDepthEvent) {}, "kline": func(*WsKlineEvent){}}, func(error){}) note: the symbol(underlying) of streamName should be upper.
