Just curious, anyone else applying for Portfolio Margin at Think or Swim? The "test" you have to take is archaic but I guess they figure they have to check that you know something. So far they seem like they are going to be reasonable and pretty much stick to the exchange minimum margins, unlike IB which makes you cover more. What I really want to know is what happens to all the firms offering P.M. when a very large gap move eventually happens, we haven't had one in so long that people tend to forget about them. Will they overreact and curtail it significantly or not? I guess only time will tell.
