Advanced MQL5 Forex EA
Prompt
Create a comprehensive MQL5 Expert Advisor (EA) script for MetaTrader 5 that implements an advanced Forex trading bot integrating multiple technical indicators, adaptive risk management, and time-based trading restrictions as specified below. --- ### Core Requirements: - **Market Sensing Indicators:** Implement EMA (Exponential Moving Average), RSI (Relative Strength Index), MACD (Moving Average Convergence Divergence), Stochastic Oscillator, and Volume analysis. - **Adaptive Trade Execution:** Automated buy and sell order placement based on indicator signals, with dynamic lot sizing at 1% of the current account balance. - **Time-Restricted Trading:** Limit all trade executions strictly to the specified New York session hours, defined by customizable start and end hours. - **News Event Avoidance:** Detect and avoid trading during scheduled news events for the symbol using SymbolInfo() functions or alternative MQL5 news APIs. - **TP/SL Management:** Implement tailored Take Profit (TP) and Stop Loss (SL) levels appropriate for minimum account balances as low as $20. - **Automatic Reversal Handling:** Detect market reversals via divergence and indicator signals; close existing positions upon reversal detection and open reverse trades accordingly. --- ### Global Variables (to be declared in the Global section of mql5\headers\StrategyTester.mqh): - `EMA_PERIOD` (e.g., 20) - `RSI_PERIOD` (e.g., 14) - `OVERBOUGHT_THRESHOLD` (RSI or Stochastic upper bound) - `OVERSOLD_THRESHOLD` (RSI or Stochastic lower bound) - `START_HOUR` (New York session start) - `END_HOUR` (New York session end) - `MIN_ACCOUNT_BALANCE` (minimum account balance to enable trading) --- ### EA Lifecycle Functions: **1. `Init()` Function:** - Validate all input parameters for acceptable ranges. - Initialize and attach all required indicators (EMA, RSI, MACD, Stochastic). - Calculate adaptive lot size as 1% of the current account balance. **2. `DeInit()` Function:** - Clean up and detach indicators. - Free any allocated resources. **3. Custom News Detection Indicator/Module:** - Create or integrate a module that identifies upcoming or current news events affecting the traded symbol within the trading session hours. - Prevent trade opening during detected news events. **4. `Calculate()` Function (Main Trading Logic):** - Calculate current values of EMA, RSI, MACD, Stochastic Oscillator, and analyze volume data. - Confirm current time is within `START_HOUR` and `END_HOUR`, and no news events are detected. - Identify trade signals based on combined indicators: - **Buy Signal:** Price > EMA and RSI < oversold threshold AND confirm bullish divergences (MACD, RSI), Stochastic %K crossing %D in oversold zone, and supportive volume trends. - **Sell Signal:** Price < EMA and RSI > overbought threshold AND confirm bearish divergences (MACD, RSI), Stochastic %K crossing %D in overbought zone, and volume confirmation. - Execute trades: - Open new trades with calculated lot size, setting SL and TP levels appropriately considering minimum balance. - Modify existing orders if necessary. - Detect reversals: - If reversal signals occur, close existing open positions and initiate reverse trades. **5. Order Management Functions:** - Implement `OrderSend()` wrapper that handles order opening/modification including SL/TP setting. - Implement `OrderDelete()` to close existing orders safely by ticket. --- ### Testing and Optimization: - Include inline code comments explaining logic and parameters. - Provide notes on optimizing parameters such as EMA/RSI periods and thresholds. - Support backtesting on historical data specifically within New York session hours and optionally on demo accounts for live strategy validation. --- # Output Format - Deliver a full, well-commented MQL5 EA source code file (.mq5) implementing all above components. - Ensure clear modular structure separating initialization, indicator calculation, signal generation, order execution, and cleanup. - Document global variables and input parameter usage. --- # Example Behavior (conceptual): - On receiving a price bar, EA calculates EMA(20), RSI(14), MACD histogram, Stochastic %K and %D, and analyzes volume. - If price > EMA(20) and RSI < 30 with bullish MACD divergence and Stochastic %K crosses above %D in the oversold region, and volume confirms upward momentum within New York session hours (e.g., 14:30 to 21:00 EST), EA opens a buy order with lot size = 1% balance. - If price reverses or bearish divergence is detected, EA closes buy order and opens a corresponding sell order. - All trades have SL and TP set respecting the minimum account balance constraints. --- Ensure robust error handling, parameter validation, and compliance with MQL5 programming standards throughout. The final product should serve as a ready-to-use, optimized Forex trading EA designed by an expert with a deep understanding of the MQL5 language and Forex trading strategies.
