How to create a line object in MQL5

Introduction and Objective:
- The tutorial discusses the creation of a horizontal line object in MQL5. This line moves to the highest candle within the last one hundred candles on the chart. Such a line can be useful for defining a trading range or measuring the difference between the highest and lowest candles.
Initial Setup in MetaEditor:
- Users are instructed to open the MetaEditor by clicking a specific icon or pressing the F4 key.
- A new file is initiated within the MetaEditor, named “simple object line”.
Array Creation and Initialization:
- Two arrays, “mypricearray0” and “mypricearray1”, are created to store price data for the last three candles.
- The copyrates function populates these arrays with the necessary data.
Object Creation and Movement:
- The tutorial guides users on how to create a horizontal line object using the object create function. This line is then moved to the highest candle using the object move function.
Testing and Visualization:
- After coding, users are advised to compile the code.
- The functionality is then tested in MetaTrader using the strategy tester, providing a real-time view of the expert advisor in action.
Conclusion and Further Learning:
- The tutorial demonstrates how to create and manipulate a simple object-oriented line in MQL5. This can be a valuable tool for traders looking to visually represent specific data points or ranges on their charts.

By following this tutorial, users can effectively create and manipulate a horizontal line object in MQL5, providing a visual representation of specific data points on their trading charts.
