Same base logic, prettier histogram :)
Green bars greater than zero by ratio of HHV up days over HHV down
days. Red bars less than zero by ratio of HHV down days over HHV up
days (multiplied by -1).
Periods = Param("Periods", 20, 1, 100, 1);
UpDayVolume = IIF(Close > Open, Volume, 0);
DownDayVolume = IIF(Close <= Open, Volume, 0);
HHVUpDayVolume = HHV(UpDayVolume, Periods);
HHVDownDayVolume = HHV(DownDayVolume, Periods);
ColorBars = IIF(HHVUpDayVolume > HHVDownDayVolume, colorGreen,
colorRed);
Plot(IIF(HHVUpDayVolume > HHVDownDayVolume,
HHVUpDayVolume/HHVDownDayVolume, IIF(HHVDownDayVolume >
HHVUpDayVolume, HHVDownDayVolume/HHVUpDayVolume * -1, 0)), "HHV
Ratio", ColorBars, styleHistogram);
