What Is an Options Sweep?
Updated 2026-07-21
Quick answer
A sweep is a large order filled across multiple exchanges in rapid succession, usually to grab available liquidity quickly.
Also called: sweep, multi-exchange sweep.
Visual explainer
A sweep hits multiple exchanges nearly at once to fill size quickly. That is urgency routing, not a guaranteed directional signal.
Full definition
Unlike a single-exchange block, a sweep takes liquidity wherever it sits and shows up as multiple prints scanners roll into one event. Urgency can mean conviction or simply size that needs a fill. Read sweeps with side, premium, and whether they stack into a theme.
