Any problem with sharing mq5 source code of tradingview pine scripts in codebase

[Yashar Seyyedin]

Hello everyone. Do you think it violates rules if one converts pine scripts and shares them in codebase with reference to the original pine coder name?

[Stanislav Korotky]

It looks normal to port publicly available source codes from other languages to MQL5, but you should keep attribution to the authors, if this is an original work. You can also check licences of the original scripts before conversion and publication.

If you have obtained the Pine source code legally (it was publicly posted online, for example), that Pine code was/is in the public domain. Writing code based on its logic entirely in MQL5 generally constitutes a new work that is substantially different─and therefore, not a copyright violation.

Even if you try to do the Pine coder a solid by citing her/him in the CodeBase as Source, the link may be removed by the System or someone. This happened to me with several "converted" indicators that I posted in the CodeBase. In contrast, credits posted in the body of the CodeBase submission tend to stay put.
