Indicator coding

 

Hi everyone,

I have a indicator which I would like to attach a upper and lower bollinger bands to one of the three indicator's ma.

The Bollinger Band code is from Trade Navigator: MovingAvg (Expression , Bars used in average) - MovingStdDev (Expression , Bars used in average) * Num Std Dev.

I would like to attach the bands to the grey line ma as shown in the attachment.

Thank you very much.
