ADX Stock Indices Technical Analysis and ADX Stock Indices Signals

Developed by J. Welles Wilder

This a momentum indicator used to determine the strength of a stock indices price trend; it is derived from the DMI - Directional Movement Index which has two lines.

+DI - Positive Directional Movement Index

–DI - Negative Directional Movement Index

ADX is calculated by subtracting these two values and applying a smoothing function.

The ADX is not a directional indicator but a measure of the strength of the stock indices trend which has a scale of Zero to 100.

The higher the indicator value the stronger the trend.

A value of below 20 indicates that the stock indices market is not trending but moving in a range.

A value of above 20 confirms a buy or sell stock indices signal and indicates a new stock indices trend is emerging.

Values above 30 signifies a strong trending market.

When ADX turns down from above 30, it signifies that the current stock indices trend is losing momentum.

Directional Movement Index

Since the ADX alone is a directionless indicator it is combined with the DMI index to determine the direction of the stock indices.
