Mike - thanks for the feedback.
I get 11,778 for this one using sbrAll bars. I guess I should subtract barnum or barnum-4 for similar? Will experiment.
Of course, there is probably a much easier way to do what I want: which is to pick out the higher highs between a low and high using Zig. The problem is how to eliminate all the Zig peaks not making new highs.

> Keep in mind that although you are creating your own array (y), the length of that array is dictated by the duration of the scan/exploration/backtest/optimization. In other words, if you explore a single bar from the AA window, your code will fail since you require at least 4 bars to populate your array. Also, array indexing is zero based. So, it would be cleaner to have your elements populated starting at [0] instead of [1].
