regarding closeouts. the rules are you will need to show a maximum width IF you want the ability to trade on your prices. i think there are a lot of people who would pay a great deal of money for that so its not a great risk. options are then fine since they move less than the spot, the risk has to go to zero at a fixed equity to margin pct above zero so every trade must be in the right direcition DELTA-wise. the vega would follow once the delta is zero and is less discontinous than all the underlyers where this rule applies. the problems are imaginary and mainly because of the crookedness. otherwise we will be fannying around with option widths etc
I'm sure they'd be thrilled to be "martyrs"!!! hahaha
