Fibonanci Retracement Tool

[Quant]

Hi All,

There is no event for FibonanciTool (other than Disposed) present in TeeChart .Net.
We need to select already drawn FibonanciTool using code. How can we achieve the same?

Hello Quant,

Yes, you are right. I have added your request to bugzilla (#1174). Does the bug description fit your needs?

Thanks for your collaboration.

Hello,

i am using latest version 4.1.2015.08061 but still not getting any event.

That's because no event was added; however, a Clicked method was added which can be used like this:

Code: Select all

    FibonacciTool tool;
    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;
      tool = new FibonacciTool(tChart1.Chart);

      Candle candle = new Candle(tChart1.Chart);

      candle.FillSampleValues(40);
      tool.StartX = candle.DateValues[0];
      tool.StartY = candle.CloseValues[0];
      tool.EndX = candle.DateValues[10];
      tool.EndY = candle.CloseValues[10];

      tool.Series = candle;

      tChart1.MouseDown += TChart1_MouseDown;
    }

    private void TChart1_MouseDown(object sender, MouseEventArgs e)
    {
      tChart1.Header.Text = "FibonacciTool clicked " + tool.Clicked(e.X, e.Y);
    }

by this way selection can not be highlighted.
I want selector tool to select fibonacci. same as we are selecting rectangle or line.

You could highlight the tool by changing the Pen colors, e.g.

Code: Select all

    private void TChart1_MouseDown(object sender, MouseEventArgs e)
    {
      bool clicked = tool.Clicked(e.X, e.Y);

      for (int i = 0; i < tool.Levels.Count; i++)
      {
        tool.Levels[i].Pen.Color = clicked ? Color.Fuchsia : Color.Black;
      }
      tool.TrendPen.Color = clicked ? Color.Fuchsia : Color.Black;
    }

we dont want this work around. we want same way as we select line or rectangle tool.

How do you select a line or a rectangle tool?

with selector tool

I see, thank you. This is quite a different request to the origin request in this thread, and as such has been added to our issue tracking software with id=1325.

Hello,

Selector marks can be client coded on the Fibonacci Trendline in this way:

Code: Select all

    bool isFiboClicked = false;

    private void TChart1_MouseDown(object sender, MouseEventArgs e)
    {
      if (fibonacciTool1.Clicked(e.X, e.Y))
        isFiboClicked = true;
      else
        isFiboClicked = false;

      tChart1.Invalidate();
    }

    private void tChart1_AfterDraw(object sender, Drawing.Graphics3D g)
    {
      if (isFiboClicked)
      {
        int startX = tChart1.Axes.Bottom.CalcPosValue(fibonacciTool1.StartX);
        int startY = tChart1.Axes.Left.CalcPosValue(fibonacciTool1.StartY);
        int endX = tChart1.Axes.Bottom.CalcPosValue(fibonacciTool1.EndX);
        int endY = tChart1.Axes.Left.CalcPosValue(fibonacciTool1.EndY);

        g.Brush.Solid = true;
        g.Brush.Color = Color.Black;
        g.Rectangle(startX - 4, startY - 4, startX + 4, startY + 4);
        g.Rectangle(endX - 4, endY - 4, endX + 4, endY + 4);
      }
    }

The Arcs or alternatively drawstyled lines can also have selector marks applied to them, it requires a little more work to extract the values from the Fibonacci class.
