zlma The ZLMA (Zero Lag Exponential Moving Average) indicator page covers the concept, usage, and parameters like n_length and n_offset. This indicator, developed by John Ehlers and Ric Way, is used for moving average calculation on de-lagged data. The page also provides a visual representation of the zlma method.

import HeadTitle from '@site/src/components/General/HeadTitle.tsx';

The zero lag exponential moving average (ZLEMA) indicator was created by John Ehlers and Ric Way. The idea is do a regular exponential moving average (EMA) calculation but on a de-lagged data instead of doing it on the regular data. Data is de-lagged by removing the data from "lag" days ago thus removing (or attempting to) the cumulative effect of the moving average.

Usage

zlma [-l N_LENGTH] [-o N_OFFSET]

Parameters

Name Description Default Optional Choices
n_length Window lengths. Multiple values indicated as comma separated values. 20 True None
n_offset offset 0 True None
