BITTREX AND POLONIEX was good but, with their recent action I felt like they are doing a scam.
First POLO then REX.
both are lagging too.
Then I tried liqui and cryptopia, but not impressed.
Now i use BINANCE for sure it will surpass those major exchanges in near future.
Trading view doesn't provide BINANCE charts yet, but COINIGY does.There are rumors that Trading View is going to include BINANCE hopefully, it is the best I have used.
