What does a clearing firm do?  Which clearing firm does my broker use?  Does it matter which clearing firm my broker uses?  Site visitors have asked us these types of questions for years so give us a few minutes of your time and we will cover everything once and for all.

Clearing Firms
Clearing firms, also referred to as clearing agents or clearing partners, act as an intermediary between brokers and exchanges.  The primary duty of a clearing firm is to handle back office tasks such as trade execution, processing, confirmation, settlement and regulatory compliance.  Clearing firms are members of an exchange's clearing house and thus are authorized to clear trades for its broker customers.

Brokers can clear through a non-affiliated company, one of their own subsidiaries or self clear.  Brokers can also utilize different clearing firms to handle trades over different exchanges.  For example, optionsXpress self clears US traded securities but utilizes Apex Clearing (formally Penson Financial Services, Inc.) for clearing securities on Canadian exchanges.
