"""AD01 — Adaptive Squeeze Threshold.

Problema SQ02: sq_threshold fisso (0.8) non si adatta al regime di volatilità.
Soluzione: threshold adattivo basato su volatilità recente.

Logica:
  - Calcola volatilità rolling (std dei rendimenti su finestra 100 barre)
  - Confronta con percentile storico (rolling 500 barre)
  - Alta vol (>70° percentile) → soglia BASSA (0.65) — squeeze più "lenti"
  - Bassa vol (<30° percentile) → soglia ALTA (0.90) — squeeze "stretti"
  - Vol media → soglia standard (0.80)

Razionale: in mercati calmi, il BB si stringe molto → sq_threshold alto cattura
segnali migliori. In mercati volatili, bastano squeeze minori per essere significativi.

Anti-overfitting: solo 3 parametri (low_thr, mid_thr, high_thr), logica deterministica.
Eredita antifakeout + volume da SQ02.
