So far so good, I can only tell of coinigy on web platforms and then tabtrader application on mobile platform if you want to make use of your API to trade as well as trade multiple exchanges with the use of the API on a single platform. I have fell in love with tabtrader for a while now as a long term trader anyway, so I packed out from coinigy since it is not free and the mobile on the go thrills I get from tabtrader. So in a way, it all depends on your own style of trading, but for use of few indicators with price action analysis, tab trader is great, but for an ENORMOUS level of analysis and more indicators, coinigy should be your best bet.
