The Percentage Volume Oscillator (PVO) is the percentage difference between two moving averages of volume. The PVO oscillates around zero. The following formula is used: PVO = ((Volume_EMA_Fast - Volume_EMA_Slow) / Volume_EMA_Fast) x 100 Usage The direction of the PVO moves as well as the centerline crossovers can be used to visually determine if the volume is … [Read more...]
