Moving Average - Exponential (EMA)

 Print this Topic Previous pageReturn to chapter overviewNext page

Description

The exponential moving average is but one type of a moving average. In a simple moving average, all price data has an equal weight in the computation of the average with the oldest value removed as each new value is added. In the exponential moving average equation the most recent market action is assigned greater importance as the average is calculated. The oldest pricing data in the exponential moving average is however never removed.
