Most exchange-traded equity options in the U.S. typically have the American exercise feature. This feature allows the holder to exercise the option at any time before and including the expiration date, providing greater flexibility compared to the European exercise feature, which only allows exercise at expiration. The Asian and shout option features are less common and not typically associated with exchange-traded equity options.

Customers are generally less credit-worthy than banks, leading to higher yields on customer loans compared to interbank loans. This higher yield compensates lenders for the increased risk associated with lending to less credit-worthy borrowers.
