what it shows is the progressive historic average of volume as % of
the days volume in intraday time periods.
It would be quite easy to compare this to any other volume indicator,
although you might want to make the progressive average volume as
absolute volume rather than % of day.
Plot(Vcum/Vday*100, "Vavg Ratio", mycolor, styleArea);
becomes
Plot(Vcum, "Absolute Vavg", mycolor, styleArea);
then oif you wanted to add say the average over the past 30 days
MA(Vavg,30) you could. It might take careful definition so that you
can get meaningful results. But as with almost everything in AB yu are
only limited by your imagination, and of course level of knowledge of
writing AFL :)
