Rate of Change
The Rate of Change (ROC) is a oscillator that compares the current closing price with the closing price N periods ago. The result is a line that oscillates above and below zero. The second line is an exponential moving average of the first line. The user may change only the period length. This indicator’s definition is further expressed in the condensed code given in the calculation below.
