# anis solidscale - Elite Spot Trading Suite
# STRATEGIE : VolumeProfileAccumulation
# CATEGORIE : Volume-at-price — VWAP Rolling + Bandes
# ══════════════════════════════════════════════════════════════
#
# LOGIQUE :
# Les zones VWAP sont des "value areas" ou le prix revient.
# 1. Close < VWAP lower band (prix sous la valeur)
# 2. RSI < 50 (pas en surachat)
# 3. Volume > SMA (confirmation d'interet)
# 4. Sortie : close > VWAP + 2 ATR OU RSI > 70
