Creating two Fibonacci Indicators at once

[BerndNT]

Hi All,

I got a request from a friend to create a Fibonacci Time Extension using the co-ordinates of a Fibonacci Extension.
Is there a way to create a CustomDrawingTool, or a way to modify the existing Fibonacci Extension (with maybe an on/off toggle) to draw the Fibonacci Time Extension when the Fibonacci Extension is drawn.

To break down the flow:
1. Select DrawingTool (Custom or Fibonacci Extension)
2. Select point 1, point2 and point 3
3. Fibonacci Extension is drawn as per usual
4. Fibonacci Time Extension is drawn using the previous points 1 and 2.

Thanks in advance.

Hello BerndNT,

Welcome to the NinjaTrader forums!

This is possible but is going to require some work to isolate the Fibonacci into a new drawing tool.
The existing fibonacci's are available to view the code of in the NinjaScript Editor in the DrawingTools folder in the FibonacciTools file.

I've made a basic example of isolating a line from the Lines file into a custom drawing tool as a starting point example.

Thanks,

I will have a look at it and see if I can get anything going.
Thanks for referring me in the right direction.

I actually came across that post already and have that downloaded.
I was playing around with it, and using static values to see if I could get it to plot, but couldn't get any luck.

public static CustomLine CustomLine(NinjaScriptBase owner, string tag, int startBarsAgo, double startY, int endBarsAgo, double endY, Brush brush)
{
      Draw.FibonacciExtensions(owner, tag+"fibtest", false, startBarsAgo, startY, endBarsAgo, endY, startBarsAgo, startY);
      return CustomLine(owner, false, tag, startBarsAgo, Core.Globals.MinDate, startY, endBarsAgo, Core.Globals.MinDate, endY, brush, DashStyleHelper.Solid, 1);
}

I assume this function is what gets called when you click on CustomLine in the DrawingTools drop down.

So I added the Draw.FibonacciExtension because to my understanding that should Draw it for me.

Hello BerndNT,

You will not be able to call a draw method from a drawingtool script.
You will need to create your own new drawingtool. Isolate the fibonacci extensions, then add the logic to render the time extensions.
