Plots the NYSE, NASDAQ, AMEX UP Volume and DOWN Volume ratios as a histogram - and adds the index UVOL / DVOL ratios as a line graph.

DVOL is represented as negative - UVOL as positive. When either is above 2 its a good predictor of the day's outcome. At least - it tells you if the bulls or bears are winning the day.

I see, you are using the tickers DVOL. There are also another tickers available, e.g. DNVOL.NY

Do you maybe know the difference between DVOL and DNVOL.NY?
hello, looks interesting!
Is it possible to change the instrument? Or can you built it changeable?

@tomavientasmo, It uses fixed securities which measure up vol and down vol on the exchanges. Wouldn't make sense to change the instrument because then it wouldn't be measuring up vol and down vol? Little confused by your question.

The indicator will operate the same on all instruments viewed because its not using the current instrument only the specific UVOL and DVOL ones
@volak, ok ... will check this
thanks for your answer!
