Positive Volume Index

The Positive Volume Index (PVI) was first introduced by Norman Fosback. PVI changes on the periods in which the volume has increased compared to the previous period. The belief behind this indicator is that as volume increases, the investment community is unified with the current direction of the market. No user input is required. This indicator’s definition is further expressed in the condensed code given in the calculation below.
