Was short Crude OIL QM April future with IB and had to cover my short position due to silly expiration regulations from IB. But what really upsets me is the fact that I couldn't rollover to the next month, because it is not yet traded through IB. So I just watched Crude Oil falling like a stone after I was forced to cover. Still feel the pain of not making the money. What makes it even more painful is the fact that I was dreaming of such a price move a couple of times. Overall I think IB is OK, but after that I'm not so sure.
