Its fine as long as you understand that if you blow yourself up you have nobody to blame but yourself and you would have no recourse since you lied about your net worth.
It doesn't matter if you don't get caught. Of course, dealing with your conscience and your God are another matter.
Why would IB have anything to do with it if I blow up? It isn't much money, but then again I might catch some sort of bug and make a large deposit into the account.
I just realized you were referring to if I got blown up trading margins. I wasn't very clear in my post.
I have read one post where someone has said he was turned down by IB because he stated that he had less than 100 trades (it could have been 200 but I don't think so). I'm fairly sure that that post was on trade to win, not ET. Generally speaking, brokers are just covering themselves legally by asking how much trading experience you have. That said, some discount brokers that are tailored to experienced traders and have a minimum amount of trades/trading experience required. Cheers, TRADERguy
