Backtesting Frameworks

sickn33/antigravity-awesome-skills

This one's for anyone building trading strategy backtests who wants to avoid the usual traps. It walks you through setting up point-in-time data pipelines, realistic cost models, and event-driven simulation with proper train/validation/test splits. The focus is on production-grade infrastructure that catches lookahead bias and overfitting before they ruin your estimates. It won't give you investment advice or run live trades, but if you're testing strategies and need disciplined walk-forward analysis, it's a solid framework to follow. The implementation playbook has patterns and examples when you need them.

Backtesting Frameworks

Build robust, production-grade backtesting systems that avoid common pitfalls and produce reliable strategy performance estimates.

Use this skill when

  • Developing trading strategy backtests
  • Building backtesting infrastructure
  • Validating strategy performance and robustness
  • Avoiding common backtesting biases
  • Implementing walk-forward analysis

Do not use this skill when

  • You need live trading execution or investment advice
  • Historical data quality is unknown or incomplete
  • The task is only a quick performance summary

Instructions

  • Define hypothesis, universe, timeframe, and evaluation criteria.
  • Build point-in-time data pipelines and realistic cost models.
  • Implement event-driven simulation and execution logic.
  • Use train/validation/test splits and walk-forward testing.
  • If detailed examples are required, open resources/implementation-playbook.md.

Safety

  • Do not present backtests as guarantees of future performance.
  • Avoid providing financial or investment advice.

Resources

  • resources/implementation-playbook.md for detailed patterns and examples.
