Understanding the label.get_text() Function in Pine Script

In this tutorial, we’ll dive deep into understanding how to use the label.get_text() function, its syntax, and practical applications.

Syntax and Arguments

The syntax for the label.get_text() function is as follows:

label.get_text(id) → series string

Arguments:

• id (series label): This is the label object from which you want to get the text.

Practical Example

Let’s go through a detailed example to understand how to use the label.get_text() function in Pine Script.

//@version=5
indicator("label.get_text Demo")
demo_label = label.new(time, open, text="Open bar info", xloc=xloc.bar_time)
retrieved_text = label.get_text(demo_label)
label.new(time, close, text = retrieved_text + " updated", xloc=xloc.bar_time)

Walkthrough

1. Creating the Initial Label:
   • demo_label = label.new(time, open, text="Open bar info", xloc=xloc.bar_time): This line creates a new label at the opening price of the bar. The label displays the text “Open bar info”.
2. Retrieving Label Text:
   • retrieved_text = label.get_text(demo_label): This line uses the label.get_text() function to get the text of the demo_label. The retrieved text is stored in the variable retrieved_text.
3. Creating a New Label with Updated Text:
   • label.new(time, close, text = retrieved_text + " updated", xloc=xloc.bar_time): This line creates another label, this time at the closing price of the bar. The text for this label is the text retrieved from demo_label plus the string ” updated”.

Key Features

• Function Usability: The label.get_text() function is used to access the text of an existing label object. This is particularly useful for labels whose text changes dynamically based on script conditions.
• Syntax and Application: The function takes a single argument, the label ID, and returns the text of that label as a string. This makes it easy to retrieve and manipulate label text within your Pine Script indicator or strategy.
• Practical Use Cases: It can be used in scenarios where you need to create derivative labels based on existing ones or when you want to log or debug the text content of labels programmatically.

Conclusion and Takeaways

• The label.get_text() function is a versatile tool for retrieving the text from label objects in Pine Script.
• Its straightforward syntax allows for easy integration into your scripts, enhancing dynamic label management and creation.
• This function opens up possibilities for more interactive and responsive indicator and strategy designs by leveraging dynamic text content within labels.
