learn ADX in trading

Average Directional Index or ADX is a technical analysis indicator that can determine if a market trend is strong or weak. It provides values between 0 to 100 for the same. A value between 0-25 indicates a weak trend. A value between 25-50 indicates a fairly strong trend.

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.
