EVWMA is a quite interesting moving average where period of the MA is defined from volume itself. It incorporates volume information in a natural and logical way. The eVWMA can be looked at as an approximation to the average price paid per share.
As a volume period you can use: - Absolute volume value, for example floating number of shares. 134M for Tesla for example. - Sum of the last x bars volumes.
