Percentage Volume Oscillator (PVO)

Percentage Volume Oscillator — PPO applied to volume instead of price. The Percentage Volume Oscillator (PVO) shows the difference of two volume EMAs as a percentage of the slow EMA. It is used to detect volume trends: PVO above zero means volume is rising relative to the historical norm. Its structure is analogous to PPO/MACD.

Formula:

PVO       = (EMA(Volume, fast) - EMA(Volume, slow)) / EMA(Volume, slow) * 100
Signal    = EMA(PVO, signal)
Histogram = PVO - Signal

TriggerDirectionConditionDescription
Signal line cross up🟢 BuyThe main line crossed the signal line from below — a buy signal.The PVO line crosses the signal line from below — a bullish cross.
Signal line cross down🔴 SellThe main line crossed the signal line from above — a sell signal.The PVO line crosses the signal line from above — a bearish cross.
Zero cross up🟢 BuyThe indicator line crossed zero from below — a buy signal.The PVO line crosses the zero level from below.
Zero cross down🔴 SellThe indicator line crossed zero from above — a sell signal.The PVO line crosses the zero level from above.
Histogram crosses zero up🟢 BuyThe histogram crossed zero from below — a buy signal.The histogram (PVO) crosses the zero level from below — a bullish signal.
Histogram crosses zero down🔴 SellThe histogram crossed zero from above — a sell signal.The histogram (PVO) crosses the zero level from above — a bearish signal.
Slope turns positive🟢 BuyThe indicator’s slope turned positive — an upward reversal.The PVO line changes its slope from downward to upward — the indicator stopped falling and started rising.
Slope turns negative🔴 SellThe indicator’s slope turned negative — a downward reversal.The PVO line changes its slope from upward to downward — the indicator stopped rising and started falling.
Line diverges from signal↕️ BothThe distance between the main line and the signal line increased by the specified amount.The PVO line moves away from the signal line — momentum is strengthening.
Line converges to signal↕️ BothThe distance between the main line and the signal line decreased by the specified amount.The PVO line converges to the signal line: the distance narrows, a cross may be forming.
