You can look for vol spike , then i liked to see it "up close and personal" on Inet & levell II ...
the otherday when AAPL was pulling back and I mentioned those few large "buys" being jammed thru on the first pullback in the $79's i think after the MacWorld news of a $1Bil Qtr sales ....I jumped in right below them , and above .
Those guys usually know what they're doing ...and off mid $79's , they are now up "pretty large". Nice way to start the New Year.<G>
But even they will lock in profs after 5-6pts or so....lots of geopolitical goings on making many nervous in this rally , and still a slowing down of retails a bit into the winter/spring .
