Bittrex socket always showing connected on my side, I think you have slow internet connection with some downtime of few seconds in between. Also which browser you are using? I am using google chrome and 10 mbps internet connection here.
i probably have the slowest internet in the whole world and i am fine with bittrex socket. if my internet gets slower than it normally is, it just says "slow" in front of the socket connection.
there is a check box on top of the orderbook list saying "show all" uncheck that and things will become a lot faster because it will group the orders and won't update them as much so it will take a lot less traffic.
