Questions
Why does open interest not move during the day?
It is published once a day by the clearing house, so today's trades show up in tomorrow's open interest.
Does rising open interest mean new buyers?
It means more contracts are open; every contract has a buyer and a seller.
Is the data delayed?
Yes. Open interest is end of day, and quotes are delayed; both are labelled.
