CX is a direct-access market that is open to the public, and trading at CX will not require you to have an account with a broker. Instead, you will need to complete an application that provides us with all the information required by the rules and regulations of the market. There is no cost to become a Participant.

Your completed application is subject to review and approval by CX. Once approved, your user ID will be validated and you will have the opportunity to fund your account and then begin trading. Of course, orders to trade can only be sent by registered and approved Participants and Authorized Traders.

Becoming a Participant means you agree to be subject to the rules of CX and CX Clearinghouse.

* CX is currently accepting applications from US residents only. If you live outside the US and are interested in opening an account with us, please email your name, country of residence, and contact information to Customer Service at we will notify you if this situation changes.
