Tuesday´s Time and Sales data do not reflect round trips. I do not know if cancelled trades are simply erased in the options trading data; cancellations were not posted. So I stay with my belief that the shares were called on Tuesday because the open interest does not reflect those large volumes of calls. We can only speculate on who sold the calls / delivered the shares.
