The indicator shows the width of the Central Pivot Range. Frank Ochoa call it It Pivot Range Histogram in his book.
Use it in conjunction with the Central Pivot Range indicator.

Below is the interpretation of the reading.

CPR Width > 0.5 - Sideways or Trading Range Day,
CPR Width > 0.75 - increases the likelihood of sideways trading behavior,
CPR Width < 0.5 - Trending type of day,
CPR Width < 0.25 - increases the likelihood of a trending market.

The above reading only increases the likely-hood of the possibility and not always right.
