this thing has completely worn my ass out. I have been right about the direction of the mcclellan osc, not summation, 18 of the last 19 trading days, and you know what? There has been little correlation between the index movement and the osc fluctuation. I just realized this is why I am screwing up when I saw this today. The nas osc dropped as I knew it should, yet the friggin index went back up. nothing is going to work except going with the direction of the bp's and summations.
