Arbitrary Parameter Adjustments

Definition

Arbitrary parameter adjustments refer to the discretionary modification of variables within a financial model or trading algorithm that lack a foundation in empirical data or systematic logic. These manual overrides often serve to force a model output to align with a preconceived market narrative, undermining the integrity of quantitative risk management frameworks. By introducing subjective influence into algorithmic processes, traders frequently compromise the robustness of their predictive models during periods of high market volatility.
