Definitions
In plain terms
It shows the signed separation between the normalized oscillator and its smoothed comparison.
Technical
It begins only after both PPO and signal stages are ready and aligned under the same missing-value policy.
Scope
A zero crossing describes line equality, not guaranteed future price direction.
Formula
PPO histogram = PPO line - PPO signalPH_t=P_t-Q_t| Symbol | Meaning | Unit |
|---|---|---|
P_t | PPO line | percent |
Q_t | PPO signal line | percent |
Output unit: percentage points
Examples
- A governed lesson calculates or identifies PPO Histogram only after its parameters, state, timing, and edge cases are declared.
Common misconceptions
- A zero crossing describes line equality, not guaranteed future price direction.
