Percentage Volume Oscillator (PVO) Indicator Explained

The Percentage Volume Oscillator (PVO) is MACD aimed at volume: (fast EMA − slow EMA) of volume, as a percentage of the slow EMA. Above zero, participation is expanding; below, the crowd is leaving. It's the momentum of attention itself.

How It Works

• ((EMA12 − EMA26) of volume) ÷ EMA26 × 100, with a signal line.
• Percent scale makes it comparable across symbols.
• Spikes mark participation events; sub-zero drifts mark disinterest.

How to Trade It

Breakouts with PVO surging above zero have crowd fuel; breakouts with PVO negative are running on vapor. In trends, PVO sagging while price grinds higher warns the audience is thinning — tighten stops before everyone notices.
