IB won't let me trade options because I'm under 21. I can't believe this crap. I have a cash account on Ameritrade and they let me buy options. Before some wiseass says "then don't...", they STILL have no right to not let me trade options with them as long as I am 18 years of age. Or am I wrong? Also, is it true that you have to be at least 21 to open a margin account? And is it REQUIRED to have a margin account to trade options? Thanks.
