PPO: Percentage Price Oscillator
MACD expressed in per cent of the slow average, so it can be compared across tickers and over time.
الفكرة بكلمات بسيطة
MACD is measured in price units, so a $3,000 index and a $1 currency pair give very different numbers. PPO divides by the slow EMA and shows the gap in per cent.
طريقة الحساب
(EMA 12 − EMA 26) ÷ EMA 26 × 100; signal = EMA 9 of PPO; histogram = PPO − signal.
PPO = (EMA(12) − EMA(26)) ÷ EMA(26) × 100
Signal = EMA(PPO, 9), Histogram = PPO − Signalكيفية الاستخدام
- Same signals as MACD: signal-line crosses, zero-line crosses, divergences.
- Comparing momentum between tickers.
استخلاص النتائج
- The histogram shows whether momentum is speeding up or slowing down.
مثال
BTCUSD daily, PPO = +4.1%: the 12-day EMA is 4.1% above the 26-day EMA, a strong uptrend.

ما يجب الانتباه إليه
