Indicator Formula

The formula for this indicator is:


If the volume is greater then the yesterday volume then:
PVI = Yesterday's PVI + (((Close - Yesterday's Close)/Yesterday's Close) *Yesterday's PVI)
If today's volume is less than or equal to yesterday's volume then:
PVI = Yesterday's PVI
Allways the first element of an financial array will be a value of the most recent period considered.
