Operating Methodology & Business Rules

Posted bids and offers on the platform are transmitted over the internet through state of the art encryption technology in real time. All bids and offers are completely anonymous, however, all bids and offers are fully transparent to all participants in the market. Counterparties are revealed to one another only upon satisfactory negotiation or acceptance of transaction terms. The HMX platform contains a built in credit management matrix for bilateral transactions that is individually and securely managed by each participant company. The system security will not allow a participant company to transact with a counterparty for which it does not have pre-existing matching credit terms. Bilateral transactions settle through physical delivery at the appropriate agreed delivery location. HMX also allows participants to execute OTC cleared transactions for submissions to either CME ClearPort®, ICE Clear Europe.
