Poloniex best fits to your description. There and support levels, resistance is. And Candlestick most conveniently displayed, unlike yobit.
But in contrast to poloniex ,on yobit more altcoins. Poloniex also has a "stop limit", which is not available on yobit.
so poloniex is better but not much of a coins right? but yobit got variety of coins but dont have proper trading equipments correct?
