There are many exchanges which are going well even after many issues by the other exchanges during the bitcoin panic movement during the time of correction, like Hitbtc, Etherdelta, Zebpay, Unocoin, Bittrex, Binance. All these exchanges are been used by me personally and these exchanges are good in their services and in customer support specially Zebpay, Bittrex, Binance these three are my favourite exchanges and I am trading my big portfolios with them even today and I am quite satisfied with their services.
