I know, when the turkeys start gobbling about margin, that the last idiot is long. say good bye to your accounts.
Why are they so bloody late??? Always the same thing. IB (as well as the exchanges) should have increased the margins on the way up, not after the crash. This is just another case of closing the barn door after the horse has escaped. IB is partially responsible for this silver bubble by allowing its clients to go long with silly leverage. And CME is even more responsible. Anything less than 10% margin is a total joke. And this applies to other commodities too.
