This indicator (The "Volume-Volatility weighted Average Price" or "Double Vwap") gives an alternative to the well known standard VWAP line with some special sauce.
The standard VWAP sometimes lags on big price moves, when there's not much volume "underneath them".
This indicator tries to combat that by adding the option to weigh in large price moves in the calculation, even without large volume, and can give you faster targets after big "pumps" and "dumps".
