Meaning of BUYER in English
Anyone who enters the market to purchase a good or service. For futures, a buyer can be establishing a new position by purchasing a contract (going long), or liquidating an existing short position. Puts and calls can also be bought, giving the buyer the right to purchase or sell an underlying futures contract at a set price within a certain period of time.
