What the open interest totals measure
Open interest counts outstanding contracts after settlement. It differs from session volume, which counts contracts traded during a session. The table groups calls and puts by expiration in the captured MU chain. Each row adds the call and put counts for that expiration only, with the open interest date and chain reading beside the figures. A total across the displayed expirations describes this captured subset, rather than the entire listed market. These counts do not identify buyers, sellers, opening trades or closing trades. A change in a count also does not identify a new trade on its own. The table contains no option premiums, contract identifiers or individual strike rows. The chain reading and the settlement date describe different clocks: one dates the captured file, and the other dates the positions recorded in it. Missing readings retain their prior dated page when a saved render exists.
