In statistics, a moving average (rolling average or running average) is a calculation to analyze data points by creating a series of averages of different subsets of the full data set. It is also called a moving mean (MM) or rolling mean and is a type of finite impulse response filter.he plot line connecting all the (fixed) averages is the moving average. A moving average is a set of numbers, each of which is the average of the corresponding subset of a larger set of datum points.
The Weighted Moving Average places more importance on recent price moves; therefore, the Weighted Moving Average reacts more quickly to price changes than the regular Simple Moving Average (see: Simple Moving Average). A basic example (3-period) of how the Weighted Moving Average is calculated is presented below: Prices for the past 3 days have been $5, $4, and $8. 2  Since there are 3 periods, the most recent day ($8) gets a weight of 3, the second recent day ($4) receives a weight of 2, and the last day of the 3-periods ($5) receives a weight of just one.
