Code Repository

GitHub repositories and reproducible notebooks behind every experiment on this site.

Every data-driven claim on this site is backed by code that can be run and checked. Reproducibility is the first principle here: a result isn’t a finding until someone else can reproduce it.

This website

The full source for davidmaguire.ai is public and built with Quarto: github.com/davidolivermaguire-ai/davidmaguire.ai

Research code

Each Quant Research Lab experiment links to its own reproducible script or notebook. For example, the Monte-Carlo behind How Backtest Selection Inflates the Sharpe Ratio lives in code/backtest_overfitting.py in the repository above.

Principles

• Reproducibility first — code is published alongside the result it produces.
• Versioned — everything is tracked in Git, so results can be traced to the exact code that generated them.
• Honest — the code shows the full method, including the parts that didn’t work.
