    Article summary


    Average Directional Movement Index (ADX) is an indicator that measures the overall strength of a trend. Being a component of the Directional Movement System, ADX combines and smooths (by Moving Average) the result of two other indicators: the positive directional indicator (DMI+) and negative directional indicator (DMI-). The indicator line fluctuates in the range from 0 to +100, whereby the readings below 20 indicate trend's weakness, and readings above 40 indicate trend's strength.

    ADX = MAi x [ |DMI(+) - DMI(-)| / (DMI(+) + DMI(-)] x 100

    where:
    MAi – the Moving Average value calculated for the period
    DMI(+) – the positive Direction Movement Index value calculated for the period
    DMI(+) – the negative Direction Movement Index value calculated for the period
