The Rate Of Change (ROC) is an oscillator calculating the percentage change of the security price relative to the price a specified number of periods before. The Rate Of Change acts like an overbought/oversold oscillator. The higher the ROC, the more overbought the security; when the ROC falls, a rally might occur.1.2 Average Rate of Change of a Function. To get the average rate of change of f f from x = a x = a to x = b x = b, we compute the following ratio: Avg. Rate of Change = f (b)− f (a) b− a or Δf Δx Avg. Rate of Change = f ( b) − f ( a) b − a or Δ f Δ x.
