For the spy, resistance seems to be at 390 and 410 on the way up. I'm not sure if we get that high, but those levels are good to watch for. If we hit and retreat then hit again, watch out for a big time pull back and sell off as you indicated. We may even see a scary 320 in the coming weeks.
In the good news horizon, demand for gas seems to be falling as people are definitely driving less and prices are reflecting at the pump. Here in Florida we have dropped significantly in my local area, going from $5.05 a gallon down to $4.69 today, and this is within a week.
