I've only been trading options for a few months (comsec) now but I think I have a reasonable grasp of what's going on. My issue is, and as has been mentioned here before, the fairly large amount of margin comsec wants lodged versus OCH. In particular, it makes it nearly impossible to open up written put positions (17% intervals ????). On the other hand, I don't think I've seen any online brokers that didn't want 50% of the entire exposure and optionsxpress want you to maintain a balance of $100K+ before they'll let you even write a put. Who do you guys (gals?) recommend, especially for naked written positions. And why the extra paranoia with respect to written puts?
