For traders who are new to Git, starting with just three commands — commit, log and checkout — already covers most needs. Hosting the repository privately also provides an off-site backup of the code. A short README describing each strategy version adds useful context when results are reviewed months later.
Linking each live deployment to a specific commit hash in your trading journal makes it possible to tell later exactly which code produced which results.
Benefits:
- Full history of changes.
- Easy rollback to a working version.
- Linking code versions to backtest results.
- Branches for experiments.
- Commit after each meaningful change, with a clear message.
- Tag versions used in live trading.
- Keep credentials out of the repository.
