Aside from the commission, fees charged to clients by IBKR, including but not limited to those referenced on this website, are intended to cover the costs of execution, including exchange fees. Such fees generally reflect the exchange fee structure, but in certain circumstances may be higher or lower than the fees charged by the exchange.
IBKR may receive aggregate volume discounts that are not passed on to clients.
Subject to note 2 above, non-member exchange and regulatory fees are applied, unless a client is pre-qualified by IBKR. Contact your sales person for more information.
