This is exactly the type of thing I was warning everyone about Wed night. You cannot bet the farm on either side of the market when the market is that extended in the same direction. Obviously the opening is going to be wild, it remains to be seen what the whole day will bring. You need to trade smaller, not larger when volatility expands. If the average range size doubles, you need to trade half the amount you normally would to have equal risk. Do not plunge during these times, I can assure you in the end you will lose.

I was lucky yesterday in that my S&P system bought in at 1377, but I traded with smaller size due to the volatility that is at hand.
