Pabst: great advice! you are right! In fact, this is another reason why I still would prefer daytrading margins, to keep as little money as possible tied with my broker... of course I wouldn't keep 100% of my trading capital with ANY broker. Let's do the numbers, let's say I have 100K to play with, broker 1 lets me trade with only 25K what broker 2 asks me the full 100K. Suppose everything else is the same (commish, etc). Then, I go with broker 1, and keep 75K somewhere "safe". So my "worst case scenario" in case of broker failure with broker 1 is a loss of 25K, with broker 2 would be 100%, and I'd be out of the game!! Of course I wouldn't leverage the full 100K... If that's what you are saying, yes you are 100% right leveraging (say) 50:1 the full trading account is probabilistic suicide.
