Algorithmic Edge Erosion

Definition

Algorithmic edge erosion describes the progressive decay of alpha generation in quantitative trading strategies as market participants identify and replicate specific inefficiencies. In the context of cryptocurrency and derivatives, this phenomenon often manifests when high-frequency signal advantages diminish due to increased competition, infrastructure parity, or structural changes in liquidity provision. The degradation typically accelerates as arbitrage windows tighten, forcing firms to iterate their execution models to maintain historical profitability levels.
