TOptValue_bool

What Is It?

TOptValue_bool is a class used to define boolean (true/false) parameters in custom indicators. It allows users to enable or disable certain features through the indicator settings panel.

Use the createTOptValue_bool() method from the api object inside Init() method to create an instance.

When to Use

Use TOptValue_bool when you want to let the user:

• Toggle a feature on or off

• Show or hide additional elements

• Enable conditional behavior in your indicator

---

Syntax

public MyFlag!: TOptValue_bool;

public Init(): void {
    // Create the parameter
    this.MyFlag = this.api.createTOptValue_bool(defaultValue);

    // Register the parameter
    this.api.RegOption("MyFlag", TOptionType.BOOLEAN, this.MyFlag);
}

---

Example

export default class CustomIndicator extends IndicatorImplementation {
  public IsEnabled!: TOptValue_bool;

  public Init(): void {
    this.IsEnabled = this.api.createTOptValue_bool(true);

    this.api.RegOption("IsEnabled", TOptionType.BOOLEAN, this.IsEnabled);
  }

  public Calculate(index: number): void {
    if (!this.IsEnabled.value) {
      return;
    }

    // Perform calculations only if enabled
  }
}

In this example:

• IsEnabled allows the user to toggle indicator logic on or off.

• Inside Calculate(), the logic runs only if the toggle is true.

---

Notes

• Don't forget to register string parameters using this.RegOption inside the Init method.
• You can use the value directly in Calculate, OnShow, or other methods as needed.
• Access the value with this.MyFlag.value.
