Takes Tradingviews Upside Volume for NYSE and divides it by Total Volume on NYSE.
Tradingview's data source generally has different volume figures than say the Wall Street Journal. Therefore, this indicator is an estimate.
10% upside volume shows extreme panic and is consistent with market sell offs.
90% upside days, following a decline, are often occur within...
Calculating NYSE Up Volume (UPVOL.NY) vs NYSE Down Volume (DNVOL.NY). The triangles appear when the ratio exceeds 90% in either direction.
Also has the option to switch to NQ, US, DJ, AM, or AX tickers.
Credit to @MagicEins for the original script:
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.
Really simple to use / edit to your needs
