Between 400-410. Next day opened down almost 20k, but closed down less than 3k due to the monster rally.

Man--do you realize how lucky we all were with that one?  I went delta neutral, but was at 360/440. Was able to get out with a tiny (~15%) profit, but I was sweating hard.  
  
 On the other hand, I got completely fucked by CSX today. Couldve walked with a wash at open, but got greedy (and maybe got lulled into it by NFLX the day before), and ended up with 'only' a 150% loss.
