## Parameter Sensitivity Testing

Parameter sensitivity testing involves evaluating how a model's performance changes in response to small adjustments in its input parameters. If a strategy's performance fluctuates wildly with minor changes, it is likely overfitted and lacks robustness.

This testing helps identify the "sweet spot" for parameters and ensures that the strategy is not overly reliant on a specific, fragile configuration. By mapping the performance landscape, traders can find regions of stability where the strategy is less likely to fail.

This is a crucial step in ensuring that the model is adaptable to changing market conditions. It builds confidence in the strategy's durability and helps manage the risk of parameter drift.

A robust strategy should perform consistently across a range of reasonable parameter values.
