I get your idea...the trouble is we can't earn interest at FXCM...it must be arbed between the pos and the neg...neg must be the interest free position...Ignored
Account 1 is in my name: Interest Free (I fill out the interest-free form)
Account 2 is in my whoever's name: Interest Paying. (Doesn't fill out the interest-free form)
My name is not on both of them. They are 2 totally separate accounts. One pays interest and the other doesn't.
This would obviously require some trust/contract between the 2 parties, but as far as FXCM is concerned, there is no relation between the 2 of them.
