Backtesting Frameworks
SkillCommerce & financeThis skill lets an AI test trading strategies against past market data to see how they would have performed. Once added, it can build backtests that account for look-ahead bias, survivorship bias, and transaction costs, so results reflect realistic conditions. Use it when developing trading algorithms or validating a strategy.
Available today. Use it from your connected AI after setup.
No other account needed.
After adding the skill, describe the trading strategy you want to test and ask the AI to backtest it. Mention any costs or biases you want the results to account for.
Then ask your AI: use the Backtesting Frameworks skill
What your AI can do with it
- Build backtests for trading strategies
- Avoid look-ahead bias in test results
- Avoid survivorship bias in test results
- Include transaction costs when evaluating a strategy
- Build backtesting infrastructure for trading algorithms
What this skill tells your AI
The instructions your AI receives, as published by agent-skills-hub/agent-skills-hub in skills/backtesting-frameworks/SKILL.md and read by ahel’s review.
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.
