Storage Option is a of with functions , keys and example object that represents an contract that may be exercised more than once at distinct times chosen by the option holder out of a set of predefined exercise-allowing times.
Each exercise involves either a) buying a certain quantity of the underlying at the open market and subsequently storing it in some storage facility or reversely b) withdrawing it from the storage facility and selling it at the market.
