The DMI Oscillator is a technical indicator which uses values of DMI in order to predict miscellaneous sides of market behavior.

Two components of DMI are used in calculation: DI+ and DI-; the DMI oscillator calculates the difference between these components and represents it as both a line and a histogram.

According to the rules described by Barbara Star in her article "The DMI Stochastic", the following market conditions can be predicted:

  • When the oscillator is positive and decreasing, a consolidation or pullback might take place. When price is in uptrend and the oscillator is positive but makes lower highs, a bearish divergence might be identified.

  • Conversely, when price is in downtrend and the oscillator is negative but keeps moving up, a bullish divergence might take place.

  • Trend continuation might be identified when the oscillator moves to the zero line and then rebounds from it.

  • In quiet markets, oscillator values fluctuating near the zero line (approx. -10 to +10 range) might signify sideways or rangebound price action.
