Hi Bruce,

I would like to know the parameters of Bollinger Band chan top and bottom.

My formula would be the average of top minus bottom in last 5 days

Thank you

Rory

The formulas for Bollinger Bands can be quite complicated.

Modelling Bollinger Bands (& Standard Deviation) in a TC PCF

The exact formula would depend on the settings of your Bollinger Bands. An Indicator Formula for a 5-period simple moving average of this might be too long and slow to be practical as a stand alone formula.

We might be able to get around this by using the Period and Average Type settings in a Custom PCF Indicator to apply a moving average to a formula for just the difference between the top and botom Bollinger Bands.
