Just for clarity; I was attempting to add additional information, not
criticize Bruce's reply. Since the context of the original question
was in fact for Plotting, I have no argument with Bruce's suggestion.
I just wanted to point out that should you eventually turn this into
a backtest, you might want to avoid the ExRem. Especially if your
code ends up using manual looping code for anything.
