38.—(1) Upon a determination by the Board that information concerning accounts may be relevant to determine whether manipulation, corner, squeeze or other market disorders exists in any commodity market, the Board may, by written notice, require such information as it thinks necessary from any person, including a member of a clearing house or a commodity broker or any customer in the commodity market, and the person concerned must provide the required information within such time as may be specified by the Board.
(2) If the Board has reason to believe that any person has failed to give the information required in the notice, it may without prejudice to any other penalty that may be imposed inform a commodity market or a clearing house which must, in the event, prohibit the execution of, or acceptance for orders of, trades on the market or a clearing house and in the months or expiration dates specified in the notice unless such trades offset open contracts of that person.
