Average Directional Index Rating
The Average Directional Movement Index Rating measures momentum change in the ADX. ADXR is calculated by adding the current ADX value and an ADX value n periods back, then dividing the sum by two. This serves to smooth the ADX values. As with the ADX, a rising ADXR reflects a strong underlying trend and likely continuation while falling ADXR suggests a weakening trend and possible trend reversal.
