How these are counted

Every SPX and SPXW option print of the session, from the options tape, summed per contract. Premium is each print's price times its size times 100, added up. Open interest is the count published before the open (the morning open interest), so Vol/OI is the day's volume against the contracts that were open when it began, shown only where that open interest is 50 or more. Unusual Vol/OI ranks contracts with at least 1,000 contracts traded. Multi-leg is the share of a contract's volume that printed together with other legs at the same timestamp, grouped and named by shape the way the order ledger names them. Every number is a count of contracts or of dollars; none of them carries a side or a direction.
