Frankly speaking, I've chose this brokerage only because it was No. 3 in a brokerage ranking (I can't even remember what what kind of rating it was). But for me it wasn't important, the only thing I was looking for was a respectable broker with a high rating.
Now, I'm trading for 4 years and I can say that rating was right, this brokerage deserves its place, at least I have 0 complaints, only positive vibes.
