Description

Wilder's Average Directional Index

Syntax

ADX(len)

Parameters

len - lookback period

Notes

Calculation uses the original Welles Wilder formula.

Wilder's exponential smoothing is equivalent to using 2*len-1 in a regular exponential moving average.

This indicator supports one-pass calculation when used in the Data Section with a non-variable length.

Example

TrendStrength: ADX(14)

ADX > 25 indicates a strong trend; values below 20 suggest a range-bound market.
