Performance Decay

Performance decay describes the gradual loss of a strategy's edge over time as market conditions evolve or the strategy becomes crowded. In the fast-paced world of cryptocurrency derivatives, strategies that are highly effective today may lose their profitability within weeks or months.

This decay can be caused by changes in market structure, increased competition from other bots, or shifts in the underlying asset liquidity. Monitoring for performance decay is a core task for systematic traders, who must constantly re-evaluate and optimize their models to stay relevant.

If decay is detected, the strategy must be either recalibrated or retired. Understanding the lifespan of a strategy is as important as its initial design, as it dictates the long-term viability of the trading desk.
