Strategy Optimizer for Backtested Investing Rules
Optimization is useful only when it makes a strategy more understandable. Stax helps users compare parameter choices, see tradeoffs, and avoid treating the highest backtest as a magic answer.

- Guardrail
- Overfit aware
The job it solves
Test strategy parameters, compare outcomes, and understand which rules improved risk-adjusted performance without losing sight of overfitting risk.

Questions people ask
What is strategy optimization?
Strategy optimization compares different parameter choices to see how they affected historical performance, risk, and consistency.
Can optimization cause overfitting?
Yes. Overfitting happens when a strategy is tuned too closely to the past. A good optimizer should make tradeoffs visible instead of hiding them.
What should I optimize first?
Start with parameters that match the strategy thesis, such as rebalance frequency, position count, ranking weights, or risk exits.
Ready to use strategy optimizer for backtested investing rules?
Start with a clear idea, test the rules, and keep the risk visible before the decision gets emotional.
