Next Steps

1. Verify CI Status: Check the GitHub Actions tab to ensure all tests, linting, and formatting checks pass on main and PRs.

2. Release a new version to PyPI

   If you get a 403 Forbidden during upload it likely means the project name backtester is already taken on PyPI. We've renamed the package to cryptolion-backtester—make sure your metadata matches.

   Update package metadata

   1. Open pyproject.toml and set:

      [project]
      name = "cryptolion-backtester"
      version = "0.1.1"
      # ...
      

   2. Commit and tag:

      git add pyproject.toml
      git commit -m "chore: rename package, bump to v0.1.1"
      git tag v0.1.1
      git push origin main --tags
      

   Clean old build artifacts

   rm -rf dist build cryptolion_backtester-*.egg-info

   python3 -m build
   twine upload dist/*
