Strartegy not visible

[Italy]

Good morning, I have written some codes but I do not see when I need to retrieve them on a chart or get backtest.
Attached the image.
What's the problem?

Hello Roberto,

Thanks for the post.

You are likely getting an error in the log tab of your Control Center describing what is happening.

When you open the menu to select an Indicator/Strategy, it will create an instance of all NinjaScript classes, and there is a custom strategy that is not instantiating properly due to an error in the StateChange method. The Strategy that is not showing up likely has an object in the class that is not getting initialized, please post a screenshot of any errors in your log so we can be certain of what the error is.

I look forward to your reply.

OK resolved.
Thank you.
Roberto
