hi Brian, plotting is a good idea.
Users Guide says: Barcount vs BarIndex() There is a fundamental difference between BarCount and BarIndex(). BarCount is a numeric variable that holds just one number (the count of elements in array). On the other hand BarIndex() is a function that returns ARRAY representing consecutive index of each bar. Seems i misunderstood. Let's see what the plot shows.
