I use Indodax, which is a trading platform in my country, there is a platform to trade and directly connect to our account, the interface there is very simple and Indodax also has ISO certification from the country. 
But now it looks like the exchange is getting a lot of bad talk due to their listings that don't pay attention to projects that are indeed strategic altcoin which in my opinion they are not good listings. I myself come from Indonesia already disappointed with the setbacks that occurred on the Indodax exchange
