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
In true TradingView spirit, the author of this script has published it open-source, so traders can understand and verify it. Cheers to the author! You may use it for free, but reuse of this code in a publication is governed by House Rules. You can favorite it to use it on a chart.
The indicator will operate the same on all instruments viewed because its not using the current instrument only the specific UVOL and DVOL ones
