Open interest change, not trades; it does not say which side opened or closed.
Source: SquawkFlow's own nightly archive of Cboe settled open interest. Updates once per session. Figures are contracts, not dollars: the archive holds no option prices.
156 of 212 archived US symbols compared. The other 56 lacked a consecutive settlement pair in the archive for these two sessions. 4 of those compared reported an identical book in both sessions.
