The Prompt
Create a fully functional Expert Advisor (EA) for the MetaTrader 5 platform using MQL5 that operates continuously 24/7 without interruption.
**Requirements:**
– Monitor the market and execute trades at any time, ensuring round-the-clock operation.
– Implement a clear, well-defined trading strategy based on:
– Moving averages
– RSI on the 5-minute (M5) timeframe
– Include customizable parameters for:
– Moving average periods
– RSI period
– Entry and exit thresholds
– Integrate robust risk management features:
– Configurable stop loss
– Take profit
– Dynamic position sizing based on a user-defined risk percentage of account equity
– Ensure the EA handles runtime errors gracefully with:
– Error checking
– Recovery mechanisms to maintain stable and continuous operation without manual intervention
– Provide comprehensive in-code comments explaining:
– Key functions
– Trading logic
– Risk management
– Error handling
– Specify any dependencies or required platform settings for proper operation.
**# Steps**
1. Define the trading platform and use MQL5 language for MetaTrader 5.
2. Develop the trading strategy logic:
– Use two moving averages (e.g., fast and slow) and RSI indicator.
– Enter a long position when:
– Fast MA crosses above slow MA
– RSI is below an oversold threshold
– Enter a short position when:
– Fast MA crosses below slow MA
– RSI is above an overbought threshold
– Exit positions based on:
– Opposite signals
– Hitting stop loss / take profit
3. Implement continuous market data monitoring and order management in the EA’s OnTick event.
4. Add risk management:
– Allow user configuration of:
– Stop loss
– Take profit (in pips)
– Risk percent for position sizing
– Calculate position size dynamically based on:
– Current account balance
– Stop loss distance
5. Include robust error handling and recovery to manage common runtime issues (e.g., failed order send, connection loss).
6. Test and debug to verify stable 24/7 operation.
**# Output Format**
Provide the complete, well-structured, and fully commented MQL5 source code of the Expert Advisor, ready for compilation and deployment on MetaTrader 5.
**# Notes**
– All code sections should include descriptive comments to clarify logic and usage.
– Highlight features and techniques included to ensure stable, uninterrupted operation.
– Mention any external dependencies or special settings in comments at the start of the code.
