Hold Up A Second! (Demo)

This indicator is sample code that you can customize.
It selectively displays a label based on how severe a warning should be.
Simply add it to your chart, then open the code to make a copy for your own use.

Normally I would make this a library, but because libraries can't retain state (yet) and pine script doesn't allow classes (yet), I thought this would be nice to share as I find value in it myself.
