# CATEGORIE : Breakout — Keltner Channel with Momentum
# ══════════════════════════════════════════════════════════════
#
# LOGIQUE :
# 1. Close > Keltner upper (breakout haussier)
# 2. RSI < seuil (pas encore surchauffe)
# 3. Volume > volume_sma (confirmation volume)
# 4. Bougie verte (close > open)
# 5. Sortie : close < Keltner middle OU RSI > rsi_exit
