Next important factor is whether 12600 holds. For the short-term bull a huge pennant/flag in the works so that would consist of a bounce off of bottom of cloud, up to around top of cloud over the next week. End of the pennant would be a good place for a big market move (much bigger than our Korea scare last night)
The chart history shows a lot of fakeouts when breaking the bottom of the cloud before a rise (March 25, July 16 for example). I'd be skeptical of shorting a big breakdown without solid confirmation.
