Definitions
In plain terms
It creates the smoothed comparison line used by the PPO histogram and crossover events.
Technical
Its seed starts from valid PPO values and therefore has a second-stage readiness delay.
Scope
The signal line remains in percentage units and is not an independently normalized price series.
Formula
PPO signal = EMA_signal(PPO line)Q_t=EMA_q(P)_t| Symbol | Meaning | Unit |
|---|---|---|
P | PPO line series | percent |
q | signal EMA period | observations |
Output unit: percent
Examples
- A governed lesson calculates or identifies PPO Signal Line only after its parameters, state, timing, and edge cases are declared.
Common misconceptions
- The signal line remains in percentage units and is not an independently normalized price series.
