OnHide

What is it?

The OnHide method is called automatically when the indicator is hidden from the chart — for example, when the user disables its visibility.

This gives you a place to clean up any visual elements or perform other logic when the indicator is no longer visible.

---

Syntax

public OnHide(): void {
    // logic after hiding the indicator
}

---

When and Why to Use It

Use OnHide when you want to:

• Remove custom chart objects (labels, lines, shapes) added by the indicator

• Free resources or stop background logic tied to visualization

• Prepare for a clean re-render when the indicator is shown again

---

Example

public OnHide(): void {
    // Custom method to remove a label created when the indicator was shown
    this.DeleteObject("InfoLabel")
}

Important Notes

• OnHide only runs when the indicator becomes hidden — not when it is removed completely.

• It pairs naturally with OnShow, helping you manage custom visual elements.
