Standard deviation indicator

Hi everyone,

Im looking for an indicator that draws confidence intervals on charts based on the standard deviation. For example, price+2 standard deviations for a 95% confidence interval.

I know there is the standard deviation indicator in metatrader, but is there anything that converts lets you chart it?

Cheers
JC

just using bollinger bands ... it is stnd dev bands around MA value.
if wanting calc basing on "price", just use period=1

Have you tried this?

u r right ... it is restrict in mt4 bb indicater not use period=1. but another platform i use period=1 is ok.

in mt4, use period=2, then ... close enough.
