brilliant idea, Jay -. I had the same some months ago <g>
I wanted to identify the 25th day back, for a daily 25-d momentum, so
I know what bar is the significant for the calculation next day.
one way is:
Create a PAINTBAR:
input:lookBACK(25); {or whatever your BO period is}
plot1[lookBACK] (high[lookBACK],"pbHI");
plot2[lookBACK] (low[lookBACK],"pbLO");
this will paint all bars BEFORE with a different colour - leaving
the ones inside the calculation with the normal colour....
(you might need to ADD 1 or subtract 1 from lookBACK, depending on
you update each tick or not - you will see)
hope it helps
