As the 9/28 is approaching, I'm considering to deposite more money into my IB account to qualify daytrader according to new margin rules. Yet I'm not confident enough to put 25K at a broker from whom I have never received a piece of paper. All my knowledge of IB is from internet. What if www.interactivebrokers.com doesn't exist any more when I wake up next moring? Does anyone here share the same concern?
