R.E.Signal: Incredibly useful script

I coded this one using Tim West's concept of range expansion bars.
It's a nice addition to switch back and forth when using his UDIO bars from the Key Hidden Levels indicator pack to analyze price action on a bar by bar basis.
The indicator plots a red or green bar signaling strong buying on selling, which almost always implies continuation, or a good chance to fade any retracements after said bars.
Cheers,
Ivan.
