I like the variety of instruments on offer here. Not only 6 asset classets, but also so many platforms to choose from. So far I tried cTrader (very difficult), MT4 (I like it a lot) and their own trading platform (rather basic, no expert advisors allowed).
Each platform has their own account types, all for different traders. There is just SO much here.
What I feel constrained in is pretty much all the platforms, despite many options, dont allow scalping with algorithms. Seems like cTrader is best for that, however FXpro doesnt have ECN accounts. They seem to be against scalping in general :(
