Exponential Moving Average (EMA) is one of the sorts of simple moving average and is one of the cases of weighted moving average, because not only price values, but weight values as well as used in its measurement. The difference is that price for entire period of observation are accounted, whereas weight is exponentially decreased and is never equal to 0, thereby assigning more weight to new prices. Upon that, exponential smoothing formula is used rather than linear arithmetical or another progression. This exponential smoothing is applied in forecasting number series.
