Barry,
BarCount is the number of cells loaded by Quick AFL. BarIndex() is the
actual bar number of ENTIRE array... therefore LastValue(BarIndex()) is the
total number of cells in data set.
if you define bi = BarIndex();
then LastValue(BarIndex()) = BarCount-1 + bi[0];
where bi[0] is the first cell loaded by Quick AFL
So if you want a particular cell number of the array that is loaded, then
ai = bi - b[0];
