Weighted Moving Average

An average in which some values count for more than others, and in which less recent values are dropped off the average. For example, if an index is weighted for prices over the previous 20 days, this means that the average price of the stocks will move more when the values with higher price move and values are removed from the average after 20 days have elapsed. This helps correct for both outdated information and the fact that averages tend to be affected by extreme values.
