Aggregated multi-exchange sweep activity
Returns “logical sweeps” — multi-exchange splits of one large order grouped by contract within a one-second execution window. Each row carries the venue list, total contracts/premium, spread position, moneyness bucket, and Skylit Flow Score / FlowBonus. The summary block adds population-level Sweep Dominance Factor (SDF) and bullish/bearish counts extrapolated from the full-day total.
