Institutional XAUUSD Multi-Timeframe Scalper (SMC/Liquidity Based) – No Grid/Martingale

I am seeking an experienced MQL5 developer to build a high-precision Gold (XAUUSD) scalping Expert Advisor. The objective is to achieve a Profit Factor (PF) of 2.0 or higher with a focus on institutional logic rather than retail lagging indicators.The EA must be designed to pass a "100% Real Ticks" backtest (Exness/Dukascopy data) over a 30-day period with a $500 initial deposit.Core Requirements & Strategy Logic:Market Structure & Liquidity: The EA must utilize Higher Timeframe (HTF) bias (M15 or H1) to identify liquidity pools (Session Highs/Lows).The Entry (M1/M5): Entry must be triggered by a "Liquidity Sweep" (Price piercing a structural level and rejecting) followed by a 1-Minute Market Structure Shift (MSS) or a VWAP rejection.No Lagging Indicators: Do not use traditional RSI/MACD/Stochastic for primary signals. I am looking for a Price Action/Volatility-based engine (Bollinger Band Deviations $\ge 3.0$ or ATR-based exhaustion).MTF Trend Filter: A hard 200 EMA filter on the M15 timeframe to ensure all scalps are aligned with the institutional trend.Strict Risk Management Rules:NO Martingale, NO Grid, NO Averaging: Every trade must have a hard, non-hidden Stop Loss.Asymmetric Risk/Reward: Aim for a 1:1.5 or 1:2 R:R ratio.The "Gross Loss" Shield: Implementation of a "Breakeven" function that triggers after a specific USD profit is reached, plus a "Trailing Stop" to lock in equity.Time-Decay Exit: A logic to close "stale" trades if they do not reach profit targets within a specific time window (e.g., 15 minutes).Spread/Slippage Protection: The EA must block entries if the live spread exceeds a user-defined threshold (Targeting $0.40 - $0.50 max for XAUUSD).Performance Targets (Backtest & Forward):Profit Factor: $\ge 2.0$.Max Relative Drawdown: $\le 15\% - 20\%$.Accuracy: High win rate based on institutional "Value Zone" entries.Account Growth: Optimized for $500 to $1,000 growth cycles.Deliverables:Clean, commented .mq5 source code.Optimized .set files for XAUUSD on M1/M5.Verification that the EA works on "Every Tick based on Real Ticks" in the MT5 Strategy Tester.Developer Requirements:Please provide examples of previous SMC or Volume-based EAs you have developed. Do not apply if you use "Recovery" or "Grid" systems. I am looking for a professional execution engine that respects market structure. If already have a file, please share a demo version.
