## Curve Fitting Risks

Curve fitting risk occurs when a quantitative model is tailored too precisely to historical data, capturing noise instead of the underlying market signal. In the context of cryptocurrency and options trading, this leads to models that perform exceptionally well in backtests but fail to predict future price movements accurately.

Because financial markets are dynamic and stochastic, a model that learns every historical fluctuation becomes rigid and loses its ability to generalize. When applied to real-time order flow or derivative pricing, such models often generate false signals or misprice risk.

Traders rely on these models to identify alpha, but over-optimization creates a false sense of security regarding performance metrics. Ultimately, curve-fitted strategies collapse when market regimes shift or when liquidity conditions deviate from the historical sample.

This phenomenon is a primary cause of catastrophic failure in algorithmic trading systems.
