Derivative in financial markets typically refers to a forward, future, option or any other hybrid contract of pre-determined fixed duration, linked for the purpose of contract fulfilment to the value of a specified real or financial asset or to an index of securities.

A futures contract means a legally binding agreement to buy or sell the underlying security on a future date, while options contract gives the buyer or holder of the contract the right (but not the obligation) to buy or sell the underlying asset at a predetermined price within or at end of a specified period.
