Percentage Price Oscillator (PPO 12/26)Momentum

Timeframe M1 · unit %

What it measures

The PPO computes the difference between EMA(12) and EMA(26) of the close, expressed as a percentage of EMA(26). Unlike the MACD which gives an absolute price difference, the PPO normalizes by the price level, making it comparable across different instruments and different price regimes.

How Janira reads it (bullish vs bearish)

A PPO of +1% means the 12-bar EMA is 1% above the 26-bar EMA - short-term average price is 1% above the longer-term trend line. A PPO of −0.5% means the reverse. Zero means both EMAs are at the same level.

In plain language

The PPO is MACD expressed as a percentage instead of points. If EMA(12) is at 105 and EMA(26) is at 100, MACD says '+5' while PPO says '+5%'. The percentage version allows comparing fast-market days with slow ones on equal footing.

Scenarios

PPO positive and rising: the short-term EMA is climbing away from the long-term EMA - trend acceleration in the upward direction.
PPO positive but flattening: the two EMAs are both positive but converging - the trend is intact but losing velocity.
PPO crossing zero from positive to negative: EMA(12) has fallen below EMA(26) - the short-term trend has reversed relative to the medium-term.
PPO reaching unusually high absolute value (±2%+): the two EMAs are very far apart for this instrument and time frame - a stretched, high-momentum condition.
