Description:
This indicator is based on Using Volume to Detect Shifts In Power by Vadim Gimelfarb, which appeared in the November 2004 issue of Stocks & Commodities.

Formula Parameters:
ATR Length: 1
TRsV Thickness: 2
Volume Thickness: 3
TRsV Color: Color.red
Volume Color: Color.blue
Display Volume: true

Notes:
The background of the bar changes to light grey when the current TRsV value exceeds the prior bar's value by more than 1.5. The related article is copyrighted material. If you are not a subscriber of Stocks & Commodities, please visit www.traders.com.
