# anis solidscale - Elite Spot Trading Suite
# STRATEGIE : ADOSCTrailing
# CATEGORIE : Trend+Volume — ADOSC + ATR Trailing Stop
# ══════════════════════════════════════════════════════════════
#
# LOGIQUE :
# L'ADOSC (Accumulation/Distribution Oscillator) mesure la pression
# acheteuse/vendeuse via le flux de volume. Quand il est positif ET
# croissant, les institutionnels accumulent.
# 1. ADOSC positif ET croissant + prix > EMA(50) → long
# 2. Sortie : ATR trailing stop (multiplicateur configurable)
# SOURCE : PyQuantLab — +65.8% annualise sur ETH
