How to read this data
This summary covers recorded single-leg sweeps and blocks with positive premium, excluding cancelled trades. It describes the covered flow, not all options-market volume. Total premium is gross traded premium; it is not net buying pressure. The interactive dashboard can use different filters and may show different totals.
Calls, puts, and execution near the bid or ask provide context but do not establish whether a position was opened or closed, whether it was part of a hedge, or where the stock will move next. The session updates after the next trading day becomes historical.
Stock prices show regular-session candles delayed at least 15 minutes. The latest view refreshes during market hours; the flow-session view places recorded trades on their original date, using interpolated stock prices between candle samples. Gamma exposure shows its separately dated public closing snapshot.
