• The Directional Movement Index (DMI) is a technical indicator that measures both the strength and direction of price movement and is designed to reduce false signals.

  • DMI uses two standard indicators, one negative (-DM) and one positive (+DN), in combination with a third, the Average Directional Index (ADX), which is not directional but shows momentum.
  • The larger the spread between the two main lines, the stronger the price trend. If +DI is much higher than -DI, the price trend is strongly up. If -DI is much higher than +DI, then the price trend is strongly down.
  • ADX measures the strength of an uptrend or downtrend; a value above 25 indicates a strong trend.
