# [JR] Multi Bollinger Heat Bands

Bollinger Bands , with incremented additional outer bands.

Set as you would normally, but with the addition of an incremental value for the added outer bands.

Defaults with Length 20, base multiplier of 2.0, and an Increment value of 0.5 for additional outer bands at 2.5 and 3.0. Adjust values to suite your needs.

All lines and zones have colour and formatting options available - because why not eh?
