Michael,

www.cboe.com reports the OI as of the beginning of a day and the volume as the option trading volume during the day.

For YHQDH, the OI is 5685 and the vol is 1525. We will see tomorrow morning if the OI is updated to (1525+5685), which will be consistent with my speculation; or to (5685-1525), which will be consistent with your point.
