Fortunately and not fortunately the only times that I have had problems with IB is when I am in a position and trying to get out...I say fortunately because at least I KNEW my status...I had not even considered the possibility that some traders not only were locked out of the market, but locked out of the market without knowing whether long, short, flat...That is a scenario which has no solution...If that happens, I just quit the IB thing altogether and go to a clearing firm because I know that my trading psyche will be shattered...
As it currently stands, I found myself on Thursday and Friday thinking twice about entering trades...This is NOT good...Instead of considering the risk of the trade, I was thinking of the secondary risk of being in the position and not being able to offset or even the thought of having to offset...Regardless of whether or not you have the secondary broker, the actual hassle of trying to cover your trades does not make all the problems go away...You still have the problems of giving back profits and not being able to manage positions the way you had planned...
As far as finding a second broker is concerned, I do not even think it is too important about all the details...So long as you are going to use IB for 95% of your trading, your cost concerns are minimal...I think the one thing you should look for is one of those high leverage brokers that will give you $750-$1k daytrade margin so you can cover your position intra-day...With 13k, if you put 2k up with the other broker you should be able to offset a 2 lot...So even if you have a 4-5 lot with IB, you should be able to cover 1/2 off of it in a worst case scenario...
