Dom, It looks like the VPT is already in Metastock as a standard indicator. It's listed under PVT. See below: The Price Volume Trend (PVT) is similar in concept to On Balance Volume (see On Balance Volume) in that it is a cumulative total of volume that is adjusted depending on changes in closing prices. But whereas OBV adds all volume on days when prices close higher and subtracts all volume on days when prices close lower, the PVT adds only a portion of the daily volume. The amount of volume added to the PVT is a function of the amount by which prices rose or fell relative to the previous day's close. PVT = (((C-ref(C,-1)) / ref(C,-1)) * V) + I Where: C = Today's closing price ref(C,-1) = Yesterday's closing price V = Today's volume I = Yesterday's Price Volume Trend The PVT is calculated by multiplying the day's volume by the percentage change of the underlying security and adding this value to a cumulative total. For example, if the security closed up 0.5% and volume was 10,000 shares, we would add 50 (i.e., 0.005 * 10,000 = 50) to the PVT. If the security had closed down 0.5%, we would have subtracted 50 from the PVT. See Plotting an Indicator for more information on plotting indicators. See Price Volume Trend for more information on the PVT parameters. Lenny
