Coolnapz,  I was watching today's action while sitting in traffic on the George Washington bridge in New York while on my home from the Thanksgiving break.  You must remember those days!  As I suspected and your analysis justifies;  it looked like a great start to the day with all buys but then the MM's started swapping spit; of course they can't let it look like everyone is buying since that would start the rally. IMO that EOD sell was an MM to MM trade just for the FUD factor.
