Circuit Breaker
A circuit breaker is an exchange halt when prices move too far too fast — a pause so the book can rebuild, not a valuation.
Definition
Circuit Breaker refers to a pause so the book can rebuild, not a valuation. Keep that definition fixed when comparing series, managers, or regimes — renaming the same tape does not create a new signal.
Why it matters
Price formation at the venue layer decides whether a signal survives implementation. When a pause so the book can rebuild, not a valuation shifts, related hedges, limits, and narratives usually need an explicit update rather than a quiet assumption.
Case
Suppose a desk is positioned for the opposite of what circuit breaker is saying. If a pause so the book can rebuild, not a valuation moves against that book, the first question is not “is the story clever?” but whether size, hedges, and stop logic still match the observation.
How to read it
Measure spread, queue, and impact at your size; paper fills are not a desk edge. Prefer a short written null hypothesis for Circuit Breaker: what would falsify the current reading in the next window?
