What is Exponential Moving Average (EMA)?

Exponential moving averages trace an asset’s average price over a preset number of periods, but unlike simple moving averages (SMA), EMA calculations give more weight to the most recent data. As a result EMAs react faster to changes in price than SMAs do. Two of the most popular EMAs in technical analysis are the 12 and 26 period moving averages.
