Quote from Andy_Trade:
TOS seems the way to go for options trading.
Unless you're trading several thousand contracts a month, IB just costs way too much.
After looking on IB website, they have a minimum of 2,000 USD a month in commissions so If I'm only trading a couple hundred options a month, then that would be 1,500 (approx) down the drain for nothing. And IB wants a deposit of 10,000 for the first five months just to make sure they get their fee. Screw that.
