## Structural Break

A structural break is a sudden, permanent shift in the underlying data-generating process, often triggered by major external events. In cryptocurrency, this could be a major protocol fork, a regulatory crackdown, or the introduction of a new institutional derivative product.

Unlike temporary fluctuations, a structural break changes the fundamental relationship between variables. If a model is not updated to account for this break, it will continue to operate on obsolete logic, leading to systematic failure.

Detecting these breaks in real-time is a high-level capability that separates robust systems from those that are brittle. It requires constant monitoring of model residuals and performance metrics to identify when the environment has fundamentally changed.
