# STRATEGIE : Github_assinscreedFC_trading_strategie__CCIMomentumTrend__20260321_144032
# CATEGORIE : Momentum — CCI Deviation Statistique
# ══════════════════════════════════════════════════════════════
#
# LOGIQUE :
# CCI mesure la deviation du prix par rapport a sa moyenne.
# 1. CCI crossover +100 (momentum fort)
# 2. CCI > +100 pendant 2 bougies (filtre persistence)
# 3. EMA trend filter + volume
# 4. Sortie : CCI < 0 (zero-crossing)
