A method of creating and trading packaged standard option collars on an
exchange is provided, as well as a trading facility for trading such
packaged standard option collars. Collars are created by identifying an
underlying asset, a first leg of a collar is determined by determining
the desired strike price for the first leg and selecting a standard
option contract traded on the exchange having a strike price closest to
the desired strike price. The second leg is determined by selecting
another standard option, the opposite of the first leg, having an option
price substantially offsetting the option price of the first leg. Once
the legs of the collar have been selected the collar package may be
listed on the exchange, and orders for the collars may be processed by
matching orders for opposite positions in the collar.
