Tells me that AD data isn't reliable for making trading decisions. Oh wait, I tossed it out YEARS ago...
Looks like if you walked away from the markets during the last 20 minutes you missed a huge rally. Typical jam up in the futures, lets see how the AD like looks today, markets are going to gap open .50%
Same thing again, big jam up overnight gap open, AD line weakens all day long, at the end of the day declines take the lead with a negative AD line.
Bull are weak, and if were not for the easy manipulation in the futures overnight, this market might look quite different. Question is how long can the bulls keep this up, bears are not very confident either.
