Summary of licensing, third-party components, and trademarks for pineforge-codegen. Not legal advice; consult counsel for your use case.
pineforge-codegen is source-available, not OSI "open source." It is distributed under the PolyForm Noncommercial License 1.0.0 with two supplemental terms — see LICENSE, which is the controlling text:
- Personal Trading exception — free to research, backtest, and trade your own capital, for an individual acting on their own behalf.
- Commercial use — companies, funds, managing third-party capital, embedding in a product, or operating a hosted/public-facing service requires a commercial license (email luis@4pass.com.tw).
Describe this project as "source-available" rather than "open source." The runtime it targets, pineforge-engine, is separate and Apache-2.0.
A pure-Python PineScript v6 → C++ transpiler that emits source against the public PineForge engine C-ABI. It implements PineScript v6 from TradingView's publicly published language documentation; it does not incorporate TradingView proprietary source. Names like "PineScript v6" are used nominatively to describe the input language.
The transpiler has no runtime dependencies (one function, transpile()). Development/test extras declared in pyproject.toml (pytest, etc.) are under their own upstream licenses. The opt-in compile checks invoke a C++ compiler against the separately-licensed Apache-2.0 engine headers; they skip cleanly without an engine checkout.
TradingView and PineScript are trademarks of their respective owners. pineforge-codegen is not affiliated with, endorsed by, or certified by TradingView. References to "PineScript v6" and any compatibility/parity statements are nominative and factual — compatibility and technical testing only, not a partnership or certification.
Contributions are accepted under a Developer Certificate of Origin (Signed-off-by). Because this project is dual-licensed (source-available + a sold commercial license), material contributions require a Contributor License Agreement granting PineForge the right to include the contribution in the commercial license; otherwise it cannot be accepted. See CONTRIBUTING (or contact luis@4pass.com.tw) before opening a material PR.
Provided "AS IS", without warranty of any kind, per the LICENSE's no-warranty / no-liability terms. Transpiler output and any downstream backtest results are not investment advice and carry no warranty of trading outcomes.
