IMMU - I also traded this last week. I ectered with an increase in price/vol, but it dried up 0.12 later. It was still early, so I gave it a little time. It started looking even weaker, so I tried to sell half my position at+0.10. 20% sold before it pulled back. It fell to my mental stop and I sold half my position at -0.10 and let the last 30% ride. It perked up eod and I sold the last +0.05.
