| The Rate-of-Change (ROC) indicator, which is also referred to as simply Momentum, is a pure [[:technical_indicators:introduction_to_technical_indicators_and_oscillators#momentum_oscillators|momentum oscillator]] that measures the percent change in price from one period to the next. The ROC calculation compares the current price with the price "n" periods ago. The plot forms an oscillator that fluctuates above and below the zero line as the Rate-of-Change moves from positive to negative. As a momentum oscillator, ROC signals include centerline crossovers, divergences and overbought-oversold readings. Divergences fail to foreshadow reversals more often than not, so this article will forgo a detailed discussion on them. Even though centerline crossovers are prone to whipsaw, especially short-term, these crossovers can be used to identify the overall trend. Identifying overbought or oversold extremes comes naturally to the Rate-of-Change oscillator. | The Rate-of-Change (ROC) indicator, which is also referred to as simply Momentum, is a pure [[:technical_indicators:introduction_to_technical_indicators_and_oscillators#momentum_oscillators|momentum oscillator]] that measures the percent change in price from one period to the next.
