From a strategy idea
to a better-informed decision.
Ask more of a promising backtest.
Understand the costs, risks and market conditions behind a result before deciding whether an idea deserves more attention.
HOW WE TEST
The result matters.
So does how you got there.
Our research engine challenges a strategy in three ways.
Learn here.
Evaluate elsewhere.
Walk-forward tests choose parameters on earlier data, then evaluate them on later, unseen periods. Future results cannot choose past rules.
Include the friction.
Low, base and high execution-cost scenarios show how spread and slippage can change a result. Gross performance is not the whole story.
Account for the search.
Checks for luck and overfitting consider the strategies and parameter combinations tested. A strong-looking curve alone is not enough.
BUILT TO QUESTION THE RESULT
Details that make
a difference.
- Historical membership
- Include former index constituents, not just the companies that survived.
- Traceable experiments
- Bind research to its strategy rules, data and code versions.
- No winner is a valid result
- A strategy that fails the checks stays a research result.
