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.
Regards
Robert
