Modified volume profile indicator and copyright

[jigitmax]

Hello!
I modified original volume profile indicator in NT8 to 3 versions: daily, weekly and intraday.
Can I sell it to others?
Am I violating copyright?

Hello jigitmax,

You are free to use any of the existing open source code as a basis for a start in your own scripts. If there is a note at the top of the file in comments and you plan to export the file as source code I would suggest to leave that and add an additional note that you made edits. That simply helps anyone later on know the source of the original code in case they need a reference for a fix. You are otherwise able to use any of the existing code you find inside the platforms default files to create new scripts that are different.

If I understood correctly, I can sell my indicator on Ninjatrader Ecosystem.
