What does Percentage volume osc measure?
MACD applied to VOLUME instead of price. It shows when trading activity is picking up or dying off, independent of direction.
How is Percentage volume osc calculated?
Take a 12-candle exponential average of volume minus a 26-candle one, and divide by the slow average as a percentage. `signal` smooths that over 9 candles, and `hist` is the gap between them.
Written by reading the engine’s real computation, not a textbook — where the two differ, the page describes what actually runs.
How do I use Percentage volume osc in a bot?
In the builder, add an indicator of type pvo (parameters: fast, default 12; slow, default 26; signal, default 9). Its output series — line, signal, hist — become operands you can compare in any entry or exit rule. The engine grades the whole rule honestly: real fills, no look-ahead, half the history held back.
