Definition. The latest snapshot of open interest in IBIT ETF option contracts by maturity date, broken down by option type (call/put).

Technical. Filtered to active contracts with maturity dates in the future and positive open interest. Each print reports open interest recorded at the close of the prior trading day. OPRA reports open interest once daily at around 06:30 ET, so the value for a given date is available the following morning and is timestamped with that date.
