TFS Volume Oscillator

TFS Volume Oscillator was authored by Bryan Strain in Stocks and Commodities Magazine 06/2000. First, the bar volume for the period is tallied as a plus or minus dependant upon a predominant open (-) or closing (+) price. This tally is then divided by the period to produce the volume oscillator plot. The user may change the period length. This indicator’s definition is further expressed in the condensed code given in the calculation below.

Calculation

//period = user defined, default is 7
//index = current bar number

iclose = 0;
iopen = 0;
vol = 0;
totV = 0;
    for (i = index - period + 1; i lessOr= index; i++)
        iclose = close[i];
        iopen = open[i];
        vol = getVolume(i)/1000000; //volume in millions
        if (iclose lessThan ioepn) totV = totV - vol;
        if (iclose moreThan ioepn) totV = totV + vol;
    endFor
Plot: tfsVo = totV / period;
