• Introduction and Objective:
  • The tutorial is centered on creating an expert advisor that leverages the Parabolic SAR (Stop and Reverse) indicator. The Parabolic SAR is a popular technical analysis tool that provides potential entry and exit points based on price movements.
• Initial Setup in MetaEditor:
  • Users are guided to open the MetaEditor by clicking on a specific icon or pressing the F4 key.
  • A new file is initiated within the MetaEditor, named “simple sar”.
• Array Creation and Initialization:
  • An array, “price data”, is established to store price data for the last three candles.
  • The array is populated using the copyrates function.
• SAR Definition and Calculation:
  • The Parabolic SAR is defined using the built-in function and is calculated based on 14 candles using the close prices.
  • An array, “mypricearray”, is set up to store the SAR values.
• Signal Generation and Logic:
  • The expert advisor checks the SAR values. If the SAR is above the price, it indicates a potential downtrend, and if it’s below the price, it suggests a potential uptrend.
  • Depending on the SAR value and its position relative to the price, appropriate trading signals are generated.
• Displaying Results:
  • A comment function is utilized to display the current SAR value and its position (above or below the price) directly on the MetaTrader chart.
• Testing and Visualization:
  • After coding, users are advised to compile the code.
  • The functionality is then tested in MetaTrader using the strategy tester, with visualization providing a real-time view of the expert advisor in action.
• Conclusion and Further Learning:
  • The tutorial demonstrates the expert advisor’s capability to effectively trade based on the Parabolic SAR indicator in MQL5.
  • The Parabolic SAR can be a standalone tool, but it’s often combined with other indicators to enhance trading strategies.

By following this tutorial, users can effectively create an expert advisor that trades based on the Parabolic SAR, allowing for informed trading decisions based on real-time signals.
