- Initial Setup in MetaEditor:
- Users are directed to open the MetaEditor either by clicking a specific icon or pressing the F4 key.
- A new file is initiated within the MetaEditor, named “simple object label”.
- Array Creation and Initialization:
- Two arrays, “mypricearray0” and “mypricearray1”, are established to store price data for the last three candles.
- The
copyrates
function is utilized to populate these arrays with the necessary price data.
- Label Creation and Customization:
- The label object is created using the
objectcreate
function, specifying the type asobjlabel
. - Various properties of the label, such as font, font size, text, and position, are set using the
objectsetstring
andobjectsetinteger
functions.
- The label object is created using the
- Displaying the Ask Price:
- The ask price is retrieved using the
symbolinfodouble
function. - The retrieved ask price is then displayed on the label, which is positioned on the MetaTrader chart.
- The ask price is retrieved using the
- Testing and Visualization:
- After the coding process, users are prompted to compile the code.
- The created label’s functionality is then tested in MetaTrader using the strategy tester, offering a real-time visualization of the label displaying the ask price.
- Conclusion and Further Learning:
- The tutorial provides a step-by-step guide on creating a dynamic label object in MQL5. This label can be customized and used to display various data, such as the ask price, on the MetaTrader chart.
