PVO (Percentage Volume Oscillator) — what it is and how to use it in trading
Definition
PVO (Percentage Volume Oscillator) uses the same formula as PPO, but applied to trading volume instead of price — the fast-minus-slow EMA difference of volume, expressed as a percentage.
How it works in the builder
The pvo operand takes fast/slow parameters (default 12 and 26), the same as ppo, except the data source is the volume column rather than the close.
What it looks like on the chart
Drawn as a separate panel, a line oscillating around zero — it rises when recent volume runs well above its own average and falls during quiet activity.
Typical use
Used as a "volume confirmation" filter for price signals, not a standalone directional signal on its own. Typical condition: pvo(12, 26) > 0 combined with a price breakout, confirming increased activity.
Common pitfalls
PVO says nothing about price direction — a volume increase confirms an up-move and a down-move equally, so it is almost always combined with a price or trend condition rather than used in isolation.
