ADX Forex Technical Analysis and ADX Forex Trading Signals

Developed by J. Welles Wilder


This a momentum indicator used to determine the strength of a 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.

Average Directional Movement Index (ADX)



The ADX is not a directional indicator but a measure of the strength of the 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 market is not trending but moving in a range.


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


Values above 30 signifies a strong trending market.


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



ADX combined with DMI - Directional Movement Index


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