License of published pinescripts and indicators

1) What is the default license of a published pine script / indicator?

2) Can I specify the license of a pine script I want to publish? If yes, how?

  • to specify a license, currently I add the following line on the top of my script. But a standardized solution would be better:

    //@license=MIT

  • The "Terms of Use" state: "Unless otherwise noted, all right, title and interest in and to TradingView, and all information made available through TradingView or its Services, in all languages, formats and media throughout the world, including all copyrights and trademarks therein, are the exclusive property of TradingView, its affiliates or its Data Providers." https://www.tradingview.com/policies/

    This would imply that every published indicator is a property of TradingView. Nevertheless the two questions above are still open. I would add the following additional questions:

    3) If I license my indicator code on another platform (e.g. GitHub) BEFORE I published it in TradingView, is the license on the other platform still valid?

    4) If I license my indicator code on another platform (e.g. GitHub) AFTER I published it in TradingView, is the license on the other platform still valid?

  • So far I have received the following answers from the TradingView support:

    Answer to questions 1 and 2: "according to developers team, Pine script is free software: you can redistribute it and/or modify it under the terms of a license of your choice."
    -> The support says "pine script" which is a programming language and not software. The support didn't answer my question about the source code I've shared.

    Then I quoted the TOS and asked "I cannot see anywhere an official statement about who owns/has the property of the indicators I share in TV. This implies by law that my source code is property of TradingView, correct?"
    Answer from support: "On that matter, please consult a solicitor."

    I asked again: "I make business with TradingView, so you have to help me. The questions are pretty simple and TradingView SHOULD know that. Please clarify:

    Does TradingView owns the source code I've shared in the TradingView website?
    Does TradingView have the copyright of the source code I've shared in the TradingView website?"
    Waiting for an answer.

  • Finally a clear answer from TV Support:

    "All the published Pine scripts are legally the property of TradingView and are subject to its terms of use."

    "We wish to highlight that that is rather a formality and many people who are doing business with TradingView have never had issues with legal rights/licenses for Pine script."

  • Then I asked the support "Can you confirm that if I open source a pine script that I have written outside of TradingView, the company TradingView will not sue me?"

    And they answered: "Sorry but we are not going to comment on this topic anymore. If you have any other questions or issues - please feel free to contact us again."

  • Well, I removed my open source pine scripts of my indicators from github, because I do not have the copyright for them. They are exclusively owned by TradingView.

  • With what you are describing to me, I personally believe this platform/service may not be conformant with what you are expecting to do from what I am reading and understanding from you. I'm not a legal expert, I'm not employed by TV, I'm just a member, so I'm not advising you on what to do in this situation. I just want to make that very clear. For instance, everything posted on "fakebuk" is members information voluntarily forfeited away from it's users to the corporation as property, all their emails, pictures, everything they type in on that service. It's their service, their legally binding terms and conditions, which includes copyright in their possession, and we all have a choice of whether to use it or not. Citizens too have rights "depending" on what country they live in, which include licensing, privacy, and others. I don't use "fakebuk". I will not be a member of that service with their extensive record of unethical abuse of it's members in every country, common knowledge now televised and published to the entire planet within seconds. History shows us businesses don't and will not survive very long over the course of time without respect to the people who use their product or services, simply put.

    Look, I can publish my code here publicly, privately, and or by invite only access, or "not at all", and that doesn't personally concern me. But then again, my interests are probably entirely different than yours. I believe TV is more worried about keeping their members happy with developing working features, than anything else. Other websites SHOULD NOT be html scraping our member ideas and code for their websites, which is I believe the intent of TVs copyright for the most part. I don't know what your intentions are, but any licensed legal advisor should be able to fully answer your questions properly regarding publishing, licensing, and copyright, so you can determine if a membership to TV suites your needs completely, especially if you're are operating a licensed business. I think I know what they might say, and you seem to possibly know much about the answer already.

    Licensing and copyright on every web site on the planet, I believe legally conflict with each other in the first place regarding planetary communications exchanges. Everything is a copy, of a copy, of a copy... from one router to millions of other routers, so mathematically speaking every court human and alien in the entire universe should be booked with copyright infringement cases until the end of universal time at current bandwidths of electron transference.

    I believe TV is a respectable company to me and most of my fellow member's, and should remain so, but if that should ever change, I will have no choice but immediately make an informative appropriate choice for myself, and whether to abort. I'm doubtful I shall ever see that day though, as long as everyone adheres to one universal law, RESPECT. Then there is privacy and publishing publicly... those last two words both having "publi" in them. I hope this spells it out for EVERYONE to consider, and I have no intention of revisiting this topic again for any comment.

  • TV updated their Terms of Service, allowing open source licenses!

    Quite from the ToS: "You can publish the script under any license. If you do not include the license in the comment section of a script, you agree that your script is licensed under the Mozilla Public License 2.0."

  • They updated that a while ago, July 26, 2019. There was this "What's New" notification:

    https://www.tradingview.com/blog/en/c...

    I believe they heard you loud and clear and took the time to address your concerns in an appropriate manner. I would have updated this if I hadn't forgotten about it, due to the one million variables in my head every day. In my opinion, I think TV made a wise and fair decision regarding publishing with licensing accommodations suitable on the planetary scale.
