Average Directional Index ADX: Formula and Significance

adx indicator formula

The positive directional index(DI+) shows the strength of positive price moves. When it’s sloping upwards, it’s a sign that the uptrend is getting stronger. The ADX identifies a strong trend when the ADX is over 25 and a weak trend when the ADX is below 20. Crossovers of the -DI and +DI lines can be used to generate trade signals. For example, if the +DI line crosses above the -DI line and the ADX is above 20, or ideally above 25, then that is a potential signal to buy.
