the account closure form was created on 12/1/2012. in itself that is proof of sorts that ib capital had no accounts prior to this date. you lot were likely their only customers, and very nicely they've done too!
i believe ib capital knew full well what was going on. and when they got the windfall of your accounts being traded out, they modified the document. the date of the modification is 19/5/2012, 2 days after their windfall of your money!!
anyone got a pre 19/5/2012 doc saved?
