Percent Price Oscillator (PPO) – What It Is & How to Trade with It

What is the Percent Price Oscillator (PPO)?

The Percent Price Oscillator (PPO) is a trend-following momentum indicator similar to the MACD but expressed as a percentage, making it more useful for comparing assets with different price scales. It measures the difference between two Exponential Moving Averages (EMAs) relative to the longer EMA.

The PPO formula is:
PPO = [(EMA(Short) – EMA(Long)) / EMA(Long)] × 100

Where:

• EMA(Short) = 12-period EMA (default setting).
• EMA(Long) = 26-period EMA (default setting).
• Signal Line: A 9-period EMA of the PPO line for trade confirmation.

Key Features of Percent Price Oscillator

• Identifies trend direction and momentum shifts.
• Works similarly to MACD but in percentage terms for better comparison.
• Helps detect overbought and oversold conditions.

How to Use PPO in Forex Trading

1. PPO Crossover Strategy

PPO generates trading signals when it crosses the signal line:

• Buy Signal: When the PPO line crosses above the signal line (bullish momentum).
• Sell Signal: When the PPO line crosses below the signal line (bearish momentum).

2. Zero Line Crossover Strategy

The zero line acts as a trend confirmation tool:

• Buy Signal: PPO crosses above zero, indicating an uptrend.
• Sell Signal: PPO crosses below zero, indicating a downtrend.

3. PPO Divergence Strategy

Divergence between price and PPO can indicate trend reversals:

• Bullish Divergence: Price forms a lower low, but PPO forms a higher low (buy signal).
• Bearish Divergence: Price forms a higher high, but PPO forms a lower high (sell signal).

4. PPO with Moving Averages

Pairing PPO with a moving average (e.g., 50 EMA) helps confirm trade signals:

• Buy when: PPO is above zero & price is above the 50 EMA.
• Sell when: PPO is below zero & price is below the 50 EMA.
