A listed option that you can exercise at any point between the day you purchase it and its expiration date is called an American-style option. All equity options are American style, no matter where the exchange on which they trade is located.
In contrast, you can exercise European-style options only on the last trading day before the expiration date, not before. Index options listed on various US exchanges may be either American- or European-style options.
