Range/ATR ratio flags compressed vs expansive regime. PM 14:30-18:00 only (W18 Edge Zone). Default 2.5 = palm-tuned.
Compares N-bar range (HH-LL) to N-bar ATR. Both in price units, so the ratio is dimensionless and stable across volatility regimes. **range/ATR ≤ 2.5** = compressed (RANGE), **range/ATR > 2.5** = expansive (TREND). Default threshold tuned for FCPO M5 PM (palm rarely trades >3× ATR in a 20-bar window during normal sessions). **FCPO-specific:** Regime call is only made inside the W18 PM Edge Zone (14:30-18:00 MYT). Outside that window, the indicator returns "Outside W18 window" — explicitly DOESN'T classify range/trend on AM or Night bars where research-edge is weak anyway. **Use as:** gate on trend-following systems (bb-pm-engine, trend-catcher-pm, wick-hunter-lite). When RANGE state, expect mean-reversion not breakout. **Combine with:** regime-meter (D1 EMA200 + ADX — different regime question), kc-lunch-squeeze (range during lunch is the tell for PM-open release).
