In the Exchange Traded Derivatives Market or Future Market, exchange acts as the main party and by trading of derivatives actually risk is traded between two parties. One party who purchases future contract is said to go “long” and the person who sells the future contract is said to go “short”. The holder of the “long” position owns the future contract and earns profit from it if the price of the underlying security goes up in the future. On the contrary, holder of the “short” position is in a profitable position if the price of the underlying security goes down, as he has already sold the future contract. So, when a new future contract is introduced, the total position in the contract is zero as no one is holding that for short or long.
