This indicator can be used to identify overbought and oversold situations. As with most momentum oscillators, it is better to look for oversold situations over the short term and when the medium-term trend is up and vice versa for overbought. You should be looking for openings in the direction of the larger trend movements, such as a pullback within a bigger uptrend. The best use of this indicator is with a trending market.
