To be honest, this is something you need to work out for yourself.
You have to bear in mind that fxcm are classified as a t2w preferred broker and patner, so any comments from certain quarters are probably going to be less than honest. Conversely, they'll get slagged off from members in the employment of their competitors. You cant believe a word you read on a forum.
Its been a few years since I checked them out, but FWIW, I'd avoid them
Its also worth noting that they have a pretty poor record when it comes to shinnanagins, and they've been the recipients of some fairly heavy fines over the years. Check out the NFA website for further details as negative comments tend to get deleted on forums where they advertise.
