Bollinger Bands Width Index

[malexe]

Does anyone have any idea how to write the code (using the wizard) for the Bollinger bands width Index with a 3-5 periods MA attached?

The BBW Index is the difference between +2 and -2SD from an average DIVIDED by the average, or 4 SD/MA

any help would be appreciated

You already have the Bandwidth indicator [albeit not written using the Formula Wizard] in the Bollinger folder of Formulas.

Thx a lot
but how do I add a moving average to the band width indicator
and how do I adjust the parameters for the values I want (MA and number of SD?)

thx again for your help
cheers

Try running a Search using the keyword bandwidth as both these topics have been covered before in the specific context of this indicator
