The ADXR component is simply a special type of moving average
(WilderMA) applied to the ADX indicator. ADXR is sometimes used
as a signal line. A buy signal occurs when ADX crosses above
ADXR, and a sell occurs when ADX crosses below ADXR. The
ADXR differs from ADX in that the ADXR is less sensitive to short,
quick reversals because the ADXR results in a "smoother" calculation.
