Multi BB Heat Vis - SMA/EMA/Breakout - r2

I don't expect to iterate any further on this script, unless any weird issue crops up.

Description and usage detailed in the comments at the top of the script. Cheers!

To repaint or not to repaint, all the relevant sources are exposed as inputs for customisation - so the choice is yours.


If you like what I do, consider buying me a nice fresh cup of tea :)

// @version=2

// Title:    "Multi BB Heat Vis - SMA/EMA/Breakout - r2".
// Revision: 2 (most likely final unless I find some serious issues)
// Author:   JayRogers
// Description / Usage:
//  - Three stacked SMA based Bollinger Bands designed just to give you a quick visual on the pressure/heat of movement.
//  - Set inner band as you would expect, then set your preferred multiplier increment for the additional outer 2 bands.
//  - Option to use EMA as alternative basis, rather than SMA.
//  - Breakout indication shapes, which have their own multiplier seperate from the BB's; but still tied to same length/period.
//  - Both high and low breakouts each have seperate selectable source options.
// r2 changes:
//  - cleaned and tightened up code a bit.
//  - revised title tags for customisation, to make things a little clearer.
//  - dropped [JR] tag, didn't realise someone else was using that.. less potential confusion between authors. Sorry other [JR]!
