DMI (Directional Movement Index)

Example

Say a chart shows +DI at 30, −DI at 12 and ADX at 28. With +DI above −DI, upward moves have been larger than downward ones, and ADX near 28 says the move is strong, so the full DMI describes a strong uptrend. If −DI later crossed above +DI while ADX sat around 15, it would describe weak selling rather than a strong downtrend.

Hypothetical numbers, for illustration only.
