Options can't be bought on margin. They lose value over time and thus can't be used as any form of collateral.

Cool if true - the one thing you want to make sure of when using the IB interface is that you don't accidentally end up on margin - which is easy fairly easy to do by accident.

(It's not that they try to get you there - it's just a trading platform for pros. A friend once told me how part if portfolio was sold automatically because of an automatic margin call when he didn't even realize hew as on margin)
