# STRATEGIE : Github_assinscreedFC_trading_strategie__CumulativeRSI__20260321_144032
# CATEGORIE : Mean-Reversion — Cumulative RSI(2) de Larry Connors
# ══════════════════════════════════════════════════════════════
#
# LOGIQUE :
# Somme du RSI(2) sur N jours. Quand la somme est tres basse,
# le marche est en survente cumulee → rebond probable.
# 1. Cumulative RSI(2) sur cum_days < cum_threshold + prix > SMA(200) → long
# 2. Sortie : Close > SMA(5) (rebond court terme)
