Percentage Price Oscillator in Crypto: Why the Value Changes Before Candle Close

PPO is MACD expressed as a percentage of the slow EMA. It moves intrabar like MACD, but is comparable across coins with different prices.

Short answer

PPO = (EMA(12) − EMA(26)) ÷ EMA(26) × 100, with a signal line (EMA of PPO) and histogram. On the live bar, both EMAs move with price, so PPO, its signal and histogram change before the close; the histogram moves most. Because it's a percentage, PPO compares momentum across assets with different prices, which MACD can't. Use closed-bar crosses.

Which part of PPO uses the live bar

ComponentUses current bar?Effect intrabar
EMA(12), EMA(26)YesMove with price
PPOYesPercentage
Signal EMA(9)YesSmoother
HistogramYesMoves most

Same intrabar behaviour as MACD, but in percent, so a 0.2% PPO move means the same on a $1 coin and a $60,000 coin.
