Up/Dn Volume Ratio

[bigtee]

I'm requesting an Up/Down volume ratio indicator. This is an indicator invented by Bill O'Neill and used by Larry McMillan.

1. - Study Title = Up/Dn Vol, cursor label = Up/Dn Vol
2. - Non-price Study
3. - Regular Study (Indicator)
4. - Detailed description

*plot study as histogram
*fixed line at 1.0
*Periods should be a user input variable, default = 50.
*For each period,
UpVol= if Close>= previous close then UpVol=Vol for that bar, otherwise UpVol=0;
DnVol = if Close<previous close then DnVol = Vol for that bar, otherwise DnVol=1 (actually would be 0, but if 0 can get a divide/0 error).

* Up/Dn Vol = sum of UpVol for input periods/sum of DnVol for input periods.
This is what gets plotted

* should work on all intraday intervals, daily and weekly
* can test on any symbol with volume

interpretation.
if indicator is above 1.0 accumulation is taking place, below 1.0 distribution is taking place.

I put together your script and placed it in the File Share area. It is in the Specialty Scripts group in the Miscellaneous folder. Name is UpDnVol.efs

Thanks Chris. This works great. Also like the different colored bars above/below 1.0. Very nice touch!
