(1) Insure, to the extent possible, that each order received from a customer which is executable at or near the market price is transmitted to the futures commission merchant carrying the account of the customer before any order in any future or in any commodity option in the same commodity for any proprietary account, any other account in which an affiliated person has an interest, or any account for which an affiliated person may originate orders without the prior specific consent of the account owner, if the affiliated person has gained knowledge of the customer's order prior to the transmission to the floor of the appropriate contract market of the order for a proprietary account, an account in which the affiliated person has an interest, or an account in which the affiliated person may originate orders without the prior specific consent of the account owner; and
(1) Disclose that an order of another person is being held by the introducing broker or any of its affiliated persons, unless such disclosure is necessary to the effective execution of such order or is made at the request of an authorized representative of the Commission, the contract market on which such order is to be executed, or a futures association registered with the Commission pursuant to section 17 of the Act; or
(i) Knowingly take, directly or indirectly, the other side of any order of another person revealed to the introducing broker or any of its affiliated persons by reason of their relationship to such other person, except with such other persons's prior consent and in conformity with contract market rules approved by or certified to the Commission.
