First time I used margin and tried taking a short position.  I wondered why the hell the stock was going up so much, so fast (no earnings, no news).  Locked in sell order of 200 shares at 1.40.  Freaked out the rest of the day as it went up and down but figured I'd leave it in over the weekend, I didn't want to take a 9 cent gain (greedy little me).  Fortunately, the stock opened 5/18 at 1.05 - I bought back at 1.065 and actually made a profit.  I'd like to say I can get used to this, but won't. I wish I bought more, but hindsight is always 20/20.  Thanks for the knowledge, Tim.
