Opt789,
Thanks for taking the time to post your detailed answer. I will have to do some additional research on PM.
I have done a bunch of RCs in the past, some with great results, others so-so. The main plays I have done have been "event-related" ones (earnings, FDA announcements etc.) where I have only held the position a day or two.
Yep, you are correct, if we get aggressive and we are wrong (about timing of event, extent of volatility collapse, extent of move on underlying) it can be a novel way to lose our money very quickly. LOL
Thanks again.

AZD,
Portfolio Margin is a change in the rules that gives the retail broker the right to charge you the same haircut requirement as an option market maker. As we have seen from IB already, they are making you cover more than the minimum and have concentration limits. For specifics I would suggest you contact the broker, you can also use IB's demo system on their site. I am guessing every broker will do things a little different but it is still too early to tell. By the way, you have to maintain 100k so you shouldn't even think about it unless you have at least 150k.
If you do not understand the methodology of the OCC's TIMS Risk Based Haircut requirements then you should just stick to Reg-T because you will be looking for simple answers to your margin questions and there are no simple answers. Portfolio margin, with regard to many option positions, will change each and every day, sometimes it will change dramatically and you wont know why (unless you understand TIMS).
Yes you can do reverse calendars, yes it will appear that you can do a lot of them for not much margin, but then your margin will change more and more. I would not recommend using PM unless you have your own dynamic risk analysis software to show you every possible outcome of stock and vol movement over the life of the position. Otherwise you will find yourself constantly out of line with the new rules and your broker will be liquidating your position. Even if you have the software you still need to understand TIMS, you may be unpleasantly surprised when the TIMS system changes your requirements one day without your basic risk software anticipating it.
If you think that reverse calendars are some new strategy that can be exploited for easy gains then you need to do a little more studying. Every market maker and prop trader (that works at a firm that allows options) has been able to do them for a very long time. There are many possible outcomes that cause you to lose money, and if you try to maximize margin then you can just lose all your money that much faster.
