Indicator Formula

The formula for this indicator is:


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