Class FibonacciExtension

Fibonacci Extensions are based on three chosen points on chart: the first two points determine the price move while the third point is the end of retracement against that move. Extension lines using Fibonacci ratios are then drawn based on the price moves. Fibonacci Extensions are used to estimate how far the price could move.

getPosition

  • Gets the current drawing tool position in axis values.

    Returns Point[]

    • Array containing all control point positions.

offDrawingToolMoved

  • Unsubscribes from the DrawingToolMoved event.

    Returns void

offPointerDown

  • Unsubscribes from the PointerDown event.

    Returns void

offPointerEnter

  • Unsubscribes from the PointerEnter event.

    Returns void

offPointerLeave

  • Unsubscribes from the PointerLeave event.

    Returns void

offPointerUp

  • Unsubscribes from the PointerUp event.

    Returns void

onDrawingToolMoved

  • Event that triggers when drawing tool's position has been changed either by dragging it or in code.

    Parameters

    • handler: Handler<DrawingToolMovedEvent>

      Event handler containing X- and Y-position parameters for each of the control points.

    Returns void

onPointerDown

  • Event that triggers when pointer is pressed down on top of the drawing tool.

    Parameters

    • handler: Handler<PointerDownEvent>

      Event handler containing the following parameters:

      -'xPosition' and 'yPosition' parameters return the current cursor position in axis values.

      -'xPositionClient' and 'yPositionClient' return the current cursor position in client coordinates (zero equals top-left corner).

      -'drawingTool' gets the drawing tool instance.

      -'isControlPoint' tells if the event was triggered by one of the drawing tool's control points.

      -'button' indicates the pressed mouse button.

    Returns void

onPointerEnter

  • Event that triggers when pointer is moved onto the drawing tool.

    Parameters

    • handler: Handler<PointerEnterEvent>

      Event handler containing the following parameters:

      -'xPosition' and 'yPosition' parameters return the current cursor position in axis values.

      -'xPositionClient' and 'yPositionClient' return the current cursor position in client coordinates (zero equals top-left corner).

      -'drawingTool' gets the drawing tool instance.

      -'isControlPoint' tells if the event was triggered by one of the drawing tool's control points.

    Returns void

onPointerLeave

  • Event that triggers when pointer is moved away from the drawing tool.

    Parameters

    • handler: Handler<PointerLeaveEvent>

      Event handler containing the following parameters:

      -'xPosition' and 'yPosition' parameters return the current cursor position in axis values.

      -'xPositionClient' and 'yPositionClient' return the current cursor position in client coordinates (zero equals top-left corner).

      -'drawingTool' gets the drawing tool instance.

      -'isControlPoint' tells if the event was triggered by one of the drawing tool's control points.

    Returns void

onPointerUp

  • Event that triggers when pointer is released on top of the drawing tool.

    Parameters

    • handler: Handler<PointerUpEvent>

      Event handler containing the following parameters:

      -'xPosition' and 'yPosition' parameters return the current cursor position in axis values.

      -'xPositionClient' and 'yPositionClient' return the current cursor position in client coordinates (zero equals top-left corner).

      -'drawingTool' gets the drawing tool instance.

      -'isControlPoint' tells if the event was triggered by one of the drawing tool's control points.

      -'button' indicates the released mouse button.

    Returns void

setExtendLines

  • Sets whether Fibonacci level lines extend to the edge of the chart.

    Parameters

    • extendLines: boolean

      Set true to extend the lines.

    Returns void

setFillEnabled

  • Sets whether areas between the Fibonacci levels are colored or not.

    Parameters

      Set true to enable the fill.

    Returns void

setLineColor

  • Sets the color of the Fibonacci Extension lines.

    Parameters

    Returns void

setShowPrices

  • Shows the price values of each Fibonacci level label.

    Parameters
