On average, how much of a available margin cushion do you keep in your trading account? Right now, I'm at about 34%. I'm itching so bad to enter more positions that expire this month, but I feel like I'd be being greedy. All of my current positions look as if they'll expire OTM, with a nice ROE, 4% for the month, which is just fine with me. A little voice in the back of my head says stay put, so that if things go wrong, I'll have enough to make some moves to avoid serious damage....but there's that 34% of available margin just sitting there... So as a percentage, how much do you think an average options guy like me should keep on the side?...my experience and knowledge have been made public on this forum for quite awhile.
