Optimizer: Custom

[spottysallrite]

I'd like to build my own optimizer. Certainly looking at the code for your "DefaultOptimizer" helps. Are there any other such scripts that I could look at?

Hello spottysallrite,

Thanks for your post.

Unfortunately, there are no other reference samples available for creating a custom Optimizer other than the DefaultOptimizer script you mentioned.

That said, you could find methods and properties unique to custom Optimizer development on this help guide page: https://ninjatrader.com/support/help.../optimizer.htm

This forum thread will be open for other community members to share their insight on developing a custom Optimizer.

Let us know if we may assist further.

Ok, do you have any suggestions regarding debugging tools? eg, Print ("Stuff") doesn't seem to work, neither does StreamWriter.

Hello spottysallrite,

Thanks for your note.

Instead of Print(), you could use Output.Process() to write a message to the Output window.

See this help guide page for more information and sample code: https://ninjatrader.com/support/help...g_concepts.htm

That seems to work only within "OnStateChange()". I need this to happen within "Iterate()".

Hello spottysallrite,

Thanks for your note.

Output.Process() does work within the Iterate() method.

I have added the sample code from the help guide linked in my previous post to the top of the Iterate() method. When an optimization is run I see prints in the NinjaScript Output window.

See the attached example script demonstrating this. Also, see the attached image.
