No one can say "no" unless he/she knows every strategy out there. So yes off course! IMO it depends on what kind of strategy you are using: I don't trust chart patterns, only indicators based on moving averages
From my personal experience, FxOpen was slow, IMO they don't want you to withdraw, while Alpari (Russia) was very fast.... I'll let you know how it goes with ATC.
FSCS , they want to cover their losses before covering people losses. If the law don't give them a time limit, they'll take forever....... maybe years !?!?
It's an automated process: they use software to read the Alpari database. There's absolutely no reason to manually check each account. The computer does the job.... I can do it in 2 minutes with my old P4 laptop, and for free.
