Yes, I sorry if I have mistaken thanks for the link. I've tried to learn how to trade and I just want to know what are the best app should I probably used.
Try TabTrader if you have Android phones. It supports many popular exchanges such as Bittrex or Binance. Not only that, you can use a lot of tools to analyze the price, such as MACD, RSI, SMA, EMA, and a lot more. I've been using it for a while now.
If you wanted to learn about technical analysis, you can visit Babypips, Tradingforex and others sites. Even though they're teaching about forex technical analysis, you can apply the same to cryptocurrencies.
In simple words, tab trader is a very good app I use effectively on my mobile while I use coinigy on the PC. These are applications that have made trading the market on series of exchanges easy.
I do not have much to do than to integrate the API of these exchanges on these 2 apps and I can be trading on those exchanges without having to login to them every single day. However, if you are referring to exchanges to be trading on, then I would say bittrex and binance should be your best bet.
