Well, I was uncovered and had just added to my long position, and I saw the market and V finally ticking up.  It looked like a nice trend, but to be safe I sold and covered half of my long position.  I was greedy, yeah, bad move, but was hoping the trend would continue. Didn't happen, so at least I was half covered which is much better than waiting the extra day and then being completely uncovered on the long.
