Dear Mrtools

Could you please add a moving average into this Bollinger Bandwidth?

This Bollinger Bandwidth is in a seperate sub window.
Bollinger Bandwidth only has one line to indicate the Bollinger Bandwidth.
Pleae add an extra line to indicate the moving average of the Bollinger Bandwidth value. that'd make the Bollinger Bandwidth has two lines.
I know this can be done within the MT4 terminal by hand. I'm trying to make EA by FXDREEMA. this function cann't be done unless Bollinger Bandwidth with a MA line of itself is in the same indicator.

thank you very much.
