Directional Movement Index (DMI)

Part of the ADX indicator, the Directional Movement Index (DMI) consists of two lines, the DMI plus line (DMI+) and the DMI minus line (DMI-), which generate buy and sell signals.

The chart below of the E-mini Russell 2000 Future shows an example of the DMI:

When the DMI+ crosses above the DMI-.

Sell Signal

When the DMI- crosses below the DMI+.

Note: The DMI crossovers can generate many false signals, other indicators should be used for confirmation of the DMI crossovers.

The Average Directional Movement Index (ADX) is an important addition to the DMI+ and DMI- indicators. In fact, the ADX is calculated using both DMI lines. Click ADX to go to the ADX webpage (see: ADX).
