SMC Setup: Sweep + CHoCH + FVG v21.1

SMC Setup: Sweep + CHoCH + FVG v21.1 (Multi-Timeframe Execution Engine)
Introducing a complete, institutional-grade Smart Money Concepts (SMC) execution algorithm. This is not just a standard sweep indicator; it is a "3D" Top-Down Analysis Engine designed to flawlessly mimic how professional human traders track order flow across multiple timeframes, natively executing on your lower-timeframe charts.

Built to solve the common pitfalls of algorithmic SMC (such as repainting, MTF blindness, and zero-width visual crashes), this indicator tracks Major (External) and Minor (Internal) liquidity simultaneously and automates your entire entry and trade management visualization.

🔥 Core Features
Multi-Timeframe (MTF) "Time-Warp" Engine: Track 15-minute and 5-minute structural liquidity sweeps natively on the 1-minute execution chart. The script uses internal mathematical multipliers and a massive 5000-bar deep memory buffer to track HTF structure without relying on laggy or repainting request.security() calls.

Dual-Fractal Liquidity Tracking: * Solid Blue Lines: Tracks Major/External Higher Timeframe liquidity peaks.

Dotted Blue Lines: Tracks Minor/Internal Lower Timeframe pullbacks for aggressive continuation order flow.

Two Selectable Entry Models:

BOS Breakout: For aggressive momentum traders. Executes the exact millisecond the micro-structure BOS (Break of Structure/CHoCH) line is cracked.

FVG Pullback: For conservative traders. Waits for a Break of Structure, verifies a Fair Value Gap has formed, and sets a limit entry exactly at the FVG boundary.

Dynamic Visual Trade Management: The script automatically generates a physical Risk Zone Box (mimicking the native TradingView Short/Long Position tools) and projects dynamic, trailing lines for your Entry, Stop Loss, TP1, TP2, and Full Target based on customizable Risk:Reward settings.

Webhook-Ready Alerts: Generates highly detailed, once-per-bar-close alerts containing dynamic strings for Entry Price, Stop Loss, and all Take Profit targets, making it perfect for automated execution via 3Commas, PineConnector, etc.

⚙️ How It Works (The Logic Flow)
The Hunt: The algorithm maps higher timeframe peaks (e.g., 15m/5m) and local micro-peaks simultaneously.

The Sweep: When price sweeps a mapped liquidity line, the algorithm "arms" the setup and locks the Stop Loss to the highest point of the sweep.

The CHoCH/BOS: It tracks the immediate local pullback prior to the sweep. If price breaks this micro-structure support, the setup is confirmed.

The Execution: Depending on your selected model, it either triggers instantly on the BOS breakout or waits for a bearish FVG pullback.

The Management: Target lines trail alongside price action and automatically lock into place the moment the trade hits the Full Target or the Stop Loss.

💡 Best Practices
Optimal Use: Load this indicator on the 1-minute chart. Set the Major HTF Multiplier to 15 and the Minor HTF Multiplier to 5. This allows the script to see 15m and 5m market structure while leveraging the 1-minute candles for surgical entries.

Asset Classes: Highly effective on high-volume assets like Indices (NAS100, US30, SPX) and Forex (EURUSD, XAUUSD) during the London or New York sessions.
