As far as I can tell,  yesterday's  volume on the S&P 500 (~GSPC) was higher even that on the day where the S&P touched the 1862 level, and is the highest since.  The market rebound from the early day's trading has to be considered impressive and acknowledged as such.  If the market internals stay strong for the next week or so, the short term bottom set yesterday may prove strong enough that if another down draft happens in Sept or October, it may hold.  A successful test of that bottom would be the best possible outcome, IMO.  

Just thinking out loud. As I said yesterday I do woder if I am being overly negative, so I am looking for data that may prove me wrong.
