Percentage Price Oscillator

What It Measures

• PPO calculates the percentage difference between a fast and slow exponential moving average.
• Unlike MACD, PPO is scale normalised, removing distortions caused by price level differences.
• PPO above zero indicates bullish momentum.
• PPO below zero indicates bearish momentum.
• Rising PPO indicates accelerating momentum and falling PPO indicates decelerating momentum.

Institutional Use

• PPO is used to evaluate momentum quality, trend persistence, and relative strength across markets.
• It is not used as a standalone signal generator.
• Its true edge lies in identifying when momentum is accelerating, decelerating, or diverging from price, which often precedes shifts in trend structure or volatility regimes.

Key Signals

• PPO crossing above zero signals shift to bullish momentum.
• Crossing below zero signals shift to bearish momentum.
• Divergence between PPO and price signals trend exhaustion.
• Flattening PPO at extremes indicates momentum exhaustion before price reacts.

Trading Playbook

• Trend continuation: enter when PPO is positive and rising, confirming momentum alignment.
• Divergence: identify PPO diverging from price at extremes and wait for price structure confirmation before fading.
• Exit when PPO crosses zero against position or divergence resolves.

When Not to Trade

• Avoid PPO crossover signals in choppy or range-bound markets.
• Do not use in isolation without structural and volatility context.
