ADXR

Summary

Smoothed variant of ADX: the average of the current ADX value and the ADX value from (period-1) bars earlier. Further damps ADX to gauge trend strength. Higher values mean a stronger trend; smoother and more lagging than ADX.

Formula

ADXR[i] = (ADX[i] + ADX[i-(period-1)]) / 2

Notes

• Wilder's original integer rounding is not applied (unreliable when values are near 1).

Inputs

• inHigh — High price of each bar
• inLow — Low price of each bar
• inClose — Close price of each bar

Outputs

• outReal — ADXR line (averaged ADX)

Parameters

Parameter	Type	Default	Accepted values	Description
optInTimePeriod	integer	14	2–100000	Smoothing period, also the bar gap between the two averaged ADX values

Properties

Numerical Stability: Initial Unstable Period — Inherited from ADX, which ADXR computes internally; tunable via ADX's unstable period.
