## Feature Stability

Feature stability refers to the consistency of a feature predictive power over time. A feature is stable if its relationship with the target variable, such as future price, remains constant across different market environments.

In crypto markets, features like social media sentiment or on-chain transaction volume can be highly unstable, meaning they might work for a week and then stop working entirely. Traders must monitor the stability of their inputs to ensure the model does not rely on transient patterns.

If a feature becomes unstable, the model will likely generate incorrect signals. Ensuring feature stability is essential for maintaining the long-term viability of automated trading systems and reducing reliance on lucky streaks.
