The Price Momentum Oscillator (PMO) is an ROC-based study developed by Carl Swenlin. PMO is essentially one-bar rate of change (relative momentum) consequently smoothed by two exponential moving averages. In addition to the main plot, the PMO study also shows a signal line: the PMO line smoothed again by a third exponential moving average. 

The main PMO line oscillates around the zero level. Extremely high readings of the PMO indicator may suggest that the stock or index is currently overbought. Vice versa, extremely low readings may signify that the stock or index is oversold. 

In addition, one may find beneficial looking for divergences between the price plot and the PMO line. These divergences may signify important changes in the trend.

Lastly, bullish and bearish crossovers of the main line and the signal line may be used as potential buy or sell signals.
