License Notes

Previous

This repository uses mixed licensing because it extends NautilusTrader, which is licensed under the GNU Lesser General Public License v3.0 or later (LGPL-3.0-or-later).

Scope

Scope License File
prediction_market_extensions/ NautilusTrader extension package LGPL-3.0-or-later NOTICE, COPYING.LESSER, COPYING
Root files with a "Derived from NautilusTrader" or "Modified by Evan Kolberg" notice LGPL-3.0-or-later COPYING.LESSER, COPYING
Everything else such as main.py, Makefile, docs, and repo metadata MIT LICENSE-MIT

The full LGPL and GPL texts are in COPYING.LESSER and COPYING. The NOTICE file lists every LGPL-covered file in the active tree, along with modification dates and upstream lineage.

Notebook runner files under backtests/ follow the same rule as .py runners: license scope depends on file-level provenance, not on the file suffix. A notebook that simply orchestrates repo runners is not automatically LGPL-covered unless it also carries Nautilus-derived provenance.

NautilusTrader Attribution

Local extensions live under prediction_market_extensions/ in their own namespace, importing from and subclassing upstream base classes. Those files carry LGPL provenance headers where applicable and are listed in NOTICE. The earlier vendored NautilusTrader tree and _nautilus_overrides/ overlay were removed from the worktree on this branch; provenance lives in git history.

Practical Meaning

  • using this repo as-is: no extra action needed
  • forking or redistributing: keep the LGPL license files, the NOTICE, and the per-file modification headers intact
  • if you modify prediction_market_extensions/, preserve those file-level notices the same way you would for any other LGPL-covered extension
  • linking against LGPL-covered modules in a proprietary project: the LGPL still requires users to be able to relink against modified versions of that code
