Visible Range

A quick and easy "at a glance" display for the viewable candles. It does repaint, but that is a non-issue, as it is simply a quick and handy tool to visually see a quick peek at the visible range.

The highest, lowest, and average are displayed, with labels for the percentage distance from the current close value and total range.
Automatic color for each based on relative distance for consistency in stable or volatile conditions.
