Before comparing across time
as of Thu 28 Aug 15:30
Open interest is in shares. Traded volume is in contracts before July 2024 and in shares after, so volumes are not compared across that change.
The lot size changed from 10,250 to 11,675 on 25 Apr 2025; contracts either side are compared in shares, not lots.
