Thanks everyone.
I was trying to perform something similar to "Market Profile" where
the bell curve would be one STD Dev from the center. But it just
occured to me that the center of the bar may not be where most of the
price action would be.
Esignal could do it intraday but you would lose your accumlated data
on the chart if you change symbols.
