Price and Volume Trend (PVT)
The Price Volume Trend (PVT) is similar to the On Balance Volume (OBV). The OBV is a cumulative total of volume times +1/-1 based on whether the close is greater or less than the previous close. However, the PVT is a cumulative total of volume times the percentage change of the close from the previous close. So, it adds more of the volume to the total when the price makes greater moves. The PVT is interpreted in the same ways as the OBV.
