A unilateral contract giving the buyer the right, but not the obligation, to buy or sell a commodity, or a futures contract, at a specified price within a certain time period. It is unilateral because only one party (the buyer) has the right to demand performance on the contract. If the buyer exercises his right, the seller (writer or grantor) must fulfill his obligation at the strike price, regardless of the current market price of the asset.
