Averages - PineCoders FAQ

█ ORIGINAL DESCRIPTION


The need to calculate averages (arithmetic mean) comes up here and there in scripts. When you want the average of a value only when a given condition has occurred, you will often not be able to use the standard sma function in Pine because it will average all values in the series. Even if you take care to use your condition to set non-conforming values to zero, this ends up skewing your results with zero values.

This script calculates:
1. The running average of all up volumes,
2. The average of last x occurrences of up volume ,
3. The average up volume occurrences in last y bars.



Look first. Then leap.
