I know all about getting stuck, I tried some of the 2x and 3x ETF's on the long side and inverse. I didnt understand the contango (spell?) effect until it was too late, I took a beating on several 10's of thousands. I'm surprised I still try to play LOL. I will never play them again unless I put a tight stop, although I dont like stop's, i feel the MM's have access and will take you out when ever they feel like it.
I know you are a fellow fisherman, I will have to post up some of my pic's
