It was pointed out to me that the prior CAT tool is really making a plot of On Balance Volume. I called it Advance / Decline, but it’s not really doing that in the official sense of the term. Anyway, it was also pointed out to me that 5 million shares of a biotech bomb move this indicator just as much as 5 million shares of GOOG, which is right, of course. So I added another file in my CAT tool release, called “CAT_DollarWOVB.xls”. It’s a dollar-weighted On Balance Volume calculation. This way, the 5 million shares of biotech bomb at $1.20 isn’t as important as the 5 million shares of GOOG at $525.
