Smoothed Rate of Change
Smoothed Rate of Change was first introduced by Fred G Schutzman in Futures magazine, April 1991. The oscillator performs a similar function to the Momentum and Rate Of Change indicators but avoids some of the weaknesses:
- Because of the smoothing the indicator is less erratic and gives fewer false signals;
- The exponential moving average ensures that the indicator only "barks" once. See Momentum for more detail.

First, identify the trend direction using a trend indicator. Smoothed Rate of Change tends to stay above zero during an up-trend and below zero during a down-trend.
Only take signals in the direction of the trend.
- In an up-trend, go long if SROC turns upwards when below zero.
- In a down-trend, go short if SROC turns downward when above zero.
Divergences add strength to buy and sell signals.

Use trailing buy and sell stops to time your entry and exit.
