Al,
If you used a ATR(1) and then plotted a 10 day simple moving average
of this ATR(1)..... it should calculate the same value as an ATR(10).
Now if you needed an "Exponential ATR" you could plot a 10 exponential
moving average of ATR(1).
I believe this is what the previous ( Mike) e-mail was trying to show.
