## Recency Bias in Model Tuning

Recency bias in model tuning is the tendency to give too much weight to the most recent market data when optimizing a trading strategy. Because the most recent data feels more relevant, developers often over-optimize their models to fit the current, short-term market environment.

This creates a strategy that is highly responsive to recent trends but vulnerable to sudden reversals. In cryptocurrency, where trends can change in hours, this bias is particularly dangerous.

It ignores the broader, long-term historical context that is necessary for building a truly robust model. Effective model tuning requires a balanced view of both recent and long-term data to ensure that the strategy is prepared for a variety of market scenarios.

Recognizing this bias helps developers avoid the trap of "chasing the market" with their parameter settings.
