Percentage Price Oscillator — the EMA difference as a percentage of the slow EMA.
The Percentage Price Oscillator (PPO) expresses the difference between the fast and slow EMA as a percentage of the slow EMA. Unlike the MACD (absolute values), the PPO lets you compare assets with different prices. Its structure is similar to the MACD: a PPO line, a signal line and a histogram.
PPO = (EMA(fast) - EMA(slow)) / EMA(slow) * 100
Signal = EMA(PPO, signal)
Parameter Type Default Range / Values Fast Lengthint 12 1-100 Signal Lengthint 9 1-50 Slow Lengthint 26 1-200
Trigger Direction Condition Description Signal line cross up 🟢 Buy The main line crossed the signal line from below to above — a buy signal. The PPO line crosses the signal line from below to above — a bullish crossover. Signal line cross down 🔴 Sell The main line crossed the signal line from above to below — a sell signal. The PPO line crosses the signal line from above to below — a bearish crossover. Zero cross up 🟢 Buy The indicator line crossed zero from below to above — a buy signal. The PPO line crosses the zero level from below to above. Zero cross down 🔴 Sell The indicator line crossed zero from above to below — a sell signal. The PPO line crosses the zero level from above to below. Histogram crosses zero up 🟢 Buy The histogram crossed zero from below to above — a buy signal. The histogram (PPO) crosses the zero level from below to above — a bullish signal. Histogram crosses zero down 🔴 Sell The histogram crossed zero from above to below — a sell signal. The histogram (PPO) crosses the zero level from above to below — a bearish signal. Slope turns positive 🟢 Buy The indicator’s slope turned positive — an upward reversal. The PPO line changes its slope from falling to rising — the indicator stopped falling and started rising. Slope turns negative 🔴 Sell The indicator’s slope turned negative — a downward reversal. The PPO line changes its slope from rising to falling — the indicator stopped rising and started falling. Line diverges from signal ↕️ Both The distance between the main line and the signal line increased by the specified amount. The PPO line moves away from the signal line — momentum is strengthening. Line converges to signal ↕️ Both The distance between the main line and the signal line decreased by the specified amount. The PPO line converges to the signal line: the distance shrinks, a crossover may be brewing.
