Open interest change, not trades; it does not say which side opened or closed.

122 of 212 archived US symbols compared. The other 90 lacked a consecutive settlement pair in the archive for these two sessions. 105 of those compared reported an identical book in both sessions.
Across the compared symbols, 1,410 contracts changed open interest: +29,328 added, -1,873 removed, net +27,455 contracts.
