Auction Opening Cross
Auction Opening Cross — Call auction that sets the opening print and imbalance.
Definition
Auction Opening Cross refers to call auction that sets the opening print and imbalance. 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 call auction that sets the opening print and imbalance 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 auction opening cross is saying. If call auction that sets the opening print and imbalance 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 Auction Opening Cross: what would falsify the current reading in the next window?
