CME filed its plans with the CFTC on Wednesday, according to the regulator, using a process that typically allows contracts to start trading within about 24 hours. CME said in June that it would list smaller-sized, round-the-clock contracts in oil that would start trading on Aug. 30. The agency said soon after CME’s announcement that it would review trading of 24/7 futures contracts across different asset classes, as well as in so-called perpetuals contracts linked to oil and energy markets.
