Live Inside Bar Coloring

Description
This script colors the current bar if it is inside the prior bar's high and low. Inside is defined as ≤ the high, and ≥ the low of the prior bar.

Utility
This gives a quick visual indication if the current bar is inside. This can indicate a choppier market. By definition, an inside bar is consolidating and not trending.

Function
Colors distinguish if the current price is above the opening price of the inside bar on a given timeframe. If you do not want to distinguish this, you can set both colors the same.
