About ADX Technical Indicator Described
ADX Technical Analysis & ADX 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 2 lines.
+DI - Positive Directional Movement Index
–DI - Negative Directional Movement Index
ADX is calculated by subtracting these 2 values & applying a smoothing function.

The ADX is not a directional technical indicator but a measure of the strength of the trend which has a scale of Zero to 100.
Higher the technical indicator value the stronger the market trend.
A value of below 20 indicates that the market is not trending but heading in a range.
A value of above 20 confirms a buy or sell signal and indicates a new trend is emerging.
Values above 30 indicates a strong trending market.
When ADX indicator turns down from above 30, it signifies that the current trend is losing momentum.
ADX combined with DMI - Directional Movement Index Indicator
