In this tutorial, the exponentially weighted moving average (EWMA) is discussed. The EWMA is often used for smoothing irregular fluctuations (i.e., noise) in a time series to permit the data analyst to better reveal trend/cycle patterns over time. Additionally, the EWMA is frequently used to...
The Exponentially Weighted Moving Average (EWMA) is a quantitative or statistical measure used to model or describe a time series. The EWMA is widely used in finance, the main applications being technical analysis and volatility modeling. The moving average is designed as such that o...

The exponentially weighted moving average (EWMA) introduceslambda, which is called the smoothing parameter. Lambda must be less than one. Under that condition, instead of equal weights, each squared return is weighted by amultiplieras follows: ...
