MCDX Smart Money

// This Pine Script® code is subject to the terms of the Mozilla Public License 2.0
// © MCDX Smart Money Indicator - Pine Script v6 Recreation
// Based on the open-source MCDX formula (RSI-based momentum classifier)
// Credits: Original concept by Mango2Juice / kgiap123 on TradingView
//
// HOW TO READ:
//   🔴 RED   = Banker (Smart Money / Institutional) → BULLISH signal
//   🟡 YELLOW = Hot Money (Short-term / Fast traders) → NEUTRAL / cautious
//   🟢 GREEN  = Retailer (Retail traders) → BEARISH signal (avoid going long)
//
//   ✅ Best to go LONG when: RED bars dominate (>50%) and GREEN is low
//   ❌ Avoid LONG when: GREEN bars dominate (retailers stuck / trapped)
