What it measures
How far the typical price (high + low + close) ÷ 3 is from its moving average, measured in mean absolute deviations and scaled so that most readings fall between −100 and +100.
How traders use it
- Breakouts: a move above +100 can mark the start of a strong uptrend, below −100 a downtrend.
- Mean reversion: extreme readings (beyond ±200) are candidates to fade in a range.
- Zero-line crossings and divergence.
