# STRATÉGIE : MARibbonStack
# CATÉGORIE : Nouvelle — Trend Following avec MA Ribbon
# ══════════════════════════════════════════════════════════════
#
# LOGIQUE :
# 1. Toutes les EMAs empilées dans l'ordre (EMA1 > EMA2 > EMA3 > EMA4 > EMA5)
# 2. Close > EMA la plus rapide
# 3. Volume > multiplicateur * moyenne
# 4. Sortie : ribbon collapse (EMA1 < EMA2 OU EMA2 < EMA3) OU close < EMA5
