Advanced MQL5 EA Generator

Create an advanced MetaTrader 5 Expert Advisor (MQL5) with a target win rate of 89% or higher, implementing Smart Money Concepts (SMC), Price Action, Spha Strength Strategy, Order Blocks, Fair Value Gaps, Break of Structure, session filtering, adaptive risk management, and continuous trade cycling (close and reopen logic). The EA must be modular, well-commented, cleanly coded in MQL5, and designed to be manually extended later. --- ## Core Requirements - Trade only high-probability setups with multiple stacked confirmations before entry. - Dynamically adapt lot size based on market conditions and recent trade results. - Close trades early upon change in conditions and reopen if logic remains valid. - Strictly limit overtrading, enforce daily trade loss limits, and protect from high drawdowns. - The EA must only trade the following symbols: XAUUSD, US30, BTCUSD, USDJPY, and GBPUSD; it must not trade any others. ## Strategy Components 1. Indicators (Filters only, no standalone signals): - EMA 9 & EMA 20 (trend direction and pullbacks) - ADX (minimum threshold for trend strength) - ATR (volatility filter and stop loss/take profit scaling) - RSI (momentum and divergence confirmation) - Optional MACD histogram for directional bias 2. Smart Money Concepts Primary Logic: - Break of Structure (BoS): Require candle close beyond structural levels, filtering minor noise. - Order Blocks (OB): Detect last bullish/bearish candle before impulsive moves; entry only when price returns to OB aligned with higher timeframe bias. - Fair Value Gaps (FVG): Identify 3-candle imbalance zones; entries only allowed on price retracement into these zones; visually draw FVG boxes on chart. 3. Price Action Rules: - Trade only on strong impulsive candles with minimum candle body-to-wick ratio. - Avoid entries during choppy or low-volume periods. - Prefer rejection candles at OB/FVG zones. 4. Spha Strength Strategy: - Implement a scoring system (0.0 to 1.0) incorporating trend strength, volatility, structure clarity, and momentum. - Only trade setups with strength score ≥ 0.89 for enhanced win probability. ## Session & Trading Time Filters - Allow trades exclusively during London, New York, and London-New York overlap sessions. - Block trades during Asian sessions (except BTCUSD), low volatility times, and spread spikes. ## Order Lock & Overtrading Protection - Limit to one open trade per symbol. - Implement cooldown periods between trades per symbol. - Lock trading after reaching max daily loss threshold; unlock at start of the next trading day. ## Risk and Money Management - Dynamic lot sizing based on a user-defined base lot. - Increase lot size after wins (with controlled multiplier), decrease after losses. - Scale lot size factoring ATR, volatility, and Spha Strength score. - Enforce configurable max risk per trade (default 1-2%). - Enforce hard limit on max trades per day and max daily drawdown with shutdown. ## Trade Cycling & Management - If a trade closes early in profit and original conditions remain valid, reopen a new trade immediately with adjusted lot size. - Close trades early if conditions weaken. - Do not perform revenge trading. ## Code Structure (Approx. 400 lines total) - Section 1 (Lines 1–100): Core Setup — properties, metadata, input definitions (checkbox booleans for features), symbol validation, session filters, indicator initialization. - Section 2 (Lines 101–200): Market Analysis — structure detection, OB and FVG detection and chart drawing, trend & strength scoring (Spha logic). - Section 3 (Lines 201–300): Trade Logic — buy/sell entry conditions, risk and lot size calculations, order execution, stop loss and take profit placement. - Section 4 (Lines 301–400): Management & Safety — trade monitoring, early close logic, re-entry logic, daily limits enforcement, logging and debugging. ## Feature Checklist - Implement boolean flags for: - Structure confirmation - Valid Order Block - FVG tapped - Valid trading session - Spha Strength score >= threshold Only execute trades when all flags are true. ## Constraints - No repainting or future candle access. - Do not include unrealistic win-rate claims in comments. - Must compile without errors on MQL5 platform. - Fully commented for manual expansion. ## Output Format - Provide the complete, syntactically correct MQL5 Expert Advisor source code file. - Include comprehensive comments explaining each major block and logic component. - The code must be modular and well-structured according to the 4-section layout described. --- Follow all instructions carefully to produce a professional, institutional-style EA with a realistic high precision, low-frequency trading approach. The final code will serve as a master template for future manual customization and extensions.
