Volume Rate of Change (VROC), is an important indicator of gauging an instrument's volume changes. It mathematically resembles Price ROC but indicates the ROC of the security's volume and not its closing price. The Volume ROC demonstrates the speed at which volume is shifting. This can turn out to be rather helpful as almost each essential chart formation, such as peaks, … [Read more...]
Volume Accumulation Oscillator
The Volume Accumulation Oscillator (VAO) is more sensitive to volume versus price than the On Balance Volume indicator. The formula for Volume Accumulation is: VAC = Volume * ( Close - High + Low / 2 ) A rising price trend will be confirmed by a rising VA line. An uptrend paired with a rising Volume Accumulation line is considered bullish while a Volume Accumulation … [Read more...]

Overview on Percentage Volume Oscillator (PVO)
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...]
On Balance Volume (OBV) : An Overview
Joe Granville introduced the On Balance Volume (OBV) indicator in his 1963 book, Granville's New Key to Stock Market Profits.A method used in technical analysis to detect momentum, the calculation of which relates volume to price change. OBV provides a running total of volume and shows whether this volume is flowing in or out of a given security.OBV attempts to detect when a … [Read more...]
