Is it possible creating own indicators like in TV?

I wonder if I can create my indicators using a pine script panel as on trading view, or whatever system do you use in Tradovate

You can create custom indicators using JavaScript. To do so, add the Code Explorer module to your workspace. To add a module, click the ‘+’ sign in the top left hand corner of the Trader application. Drag and drop the Code Explorer into your workspace. Then you can treat the Code Explorer like any code editor. You will want to have a look at the documentation here.
