Fibonacci Fan tool for NT8?

[chrille]

Hi!

I could really use the Fibonacci Fan tool for NT8. Maybe possible to make on from the existing Fib tools or is there something available already?

[NinjaTrader_PatrickG]

This tool is not currently available in NinjaTrader 8, however, this would be possible through custom programming.

Allright. I'll see if I can find someone to help me. My C# skills isn't good enough.

Write in to PlatformSupport[AT]NinjaTrader[DOT]com and one of my colleagues on the NinjaScript Team should be able to provide some examples.

Thanks NinjaTrader_PatrickG, I'll do that!

Hello chrille,

My name is Jess and I will be happy to answer any questions that come up while you develop this indicator. As a first step, I would recommend creating a "stock" indicator by visiting New -> NinjaScript Editor, right-clicking Indicator on the right, selecting "New Indicator", following along in the wizard long enough to give your Indicator a name, then clicking "Generate". I would then recommend putting bare minimum code for each of the Fibo drawing tools documented here in your OnBarUpdate method :

Fibo Retracements

I would recommend starting off with retracements as those are going to be the kinds of Fibo fans that you are probably familiar with.

If you would like the services of a certified NinjaScript consultant, please let us know and I will be happy to ask a more community savvy colleague to weigh in.

Happy coding and happy trading!

Extending IDrawObject

Hi Jess,
Is it possible / "officially supported by NT" to extend IDrawObject and add a new/custom function DrawGannFann? Something similar to custom bars.

If yes, please provide links to sample code.

Thanks in advance.

Regards

Vivek

[NinjaTrader_JessicaP]

Thank you for asking, AnkaS.

We do now directly support creating custom drawing tools, including Fibo fans, in NinjaTrader 8. You will want to investigate this link

http://ninjatrader.com/support/helpGuides/nt8/en-us/drawing_tools.htm

I am attaching a script which contains code that comes with NinjaTrader 8 and a dummied out DrawGannFann method for you to fill in

[AnkaS]

Hi Jess.
Thanks for your response and dummy code.

However clicking on "ExampleFan.cs" leads to message "Invalid Attachment specified. If you followed a valid link, please notify the administrator".

If you are on a company or public terminal it may be that your systems administrator is not allowing you to download source code files from the internet. Otherwise you may want to review your browser configuration so that you are able to download code samples from the NinjaTrader forums and other places on the internet.

As a convenience, I have pasted the code into a block here. You will want to save it as (My) Documents\NinjaTrader 8\bin\Custom\DrawingTools\ExampleFan.cs
