I've been trying to make a strategy based on Volumetric bars with ChatGPT for several hours but cannot get rid of this error.

Hello ShuyouHaYoiMonoDa,

Thank you for your post.

From our experience at this time, ChatGPT and other AI models are not adequate at generating valid NinjaScript code that function as the user has intended. We often find that these tools generate code that will call non-existent properties and methods, use improper classes or inheritance, and may have incorrect logic. Using these tools for general NinjaScript learning information may also provide incorrect responses. We highly encourage that you create a new NinjaScript yourself using the NinjaScript Editor and avoid any AI based coding tools.

While it would not be within our support model to assist with scripts generated or checked by AI tools, we would be happy to provide insight for any direct specific inquiries you may have if you would like to create this script yourself. Our support is able to assist with finding resources in our help guide as well as simple examples, and we are happy to provide guidance on how you can debug the script while running it on your machine.

To start learning NinjaScript I would suggest the following link as a starting point.
