For those who are making custom indicators, what are you using as your editor?
You should consider using the built in Code Explorer. You can add it as a component of your workspace like any other Tradovate component. You can test your code live this way and view the results without doing anything special. There’s not a great reason not to use it in my opinion.
Other good option is VSCode.
The builtin editor is functional, but not if you are into longer more detailed indicators.
