Directional Movement Index (DMI)

Description
The Directional Movement Index (DMI) assists in determining if a security is trending and attempts to measure the strength of the trend.
The DMI disregards the direction of the security. It only attempts to determine if there is a trend and that trends strength.

The indicator is made up of four indicator lines:

1. Positive Directional Indicator (+DMI) shows the difference between today’s high price and yesterday’s high price.
These values are then added up from the past 14 periods and then plotted.

2. Negative Directional Indicator (–DMI) shows the difference between today’s low price and yesterday’s low price.
These values are then summed up from the past 14 periods and plotted.

3. Average Directional Movement Index (ADX). ADX is a smoothing of the DX.

4. Average Directional Movement Index Rating (ADXR) is a simple average of today’s ADX value and the ADX from 14 periods ago.


How this indicator works:

High and rising levels of the ADX and ADXR indicate a strong trend, either up or down, signifying a trend following system may be appropriate.
Typically if the ADX is above 25 it indicates a strong trend.

Low and falling levels of the ADX and ADXR indicate a trendless market.
Typically if the ADX is below 20 it indicates a trendless market.

A buy signal is given when DMI+ crosses above DMI-. A sell signal is given when DMI- crosses above DMI+.
The ADX and ADXR lines are then used to measure the strength of these signals.
