Forex trading, foreign exchange trading or currency trading is the buying and selling of currencies on the forex market with the aim of making a profit.
Forex is the world’s most-traded financial market, with transactions worth trillions of dollars taking place every day.
While you can go short on other markets by using derivative products, such as CFDs, short selling is an inherent part of trading forex. This is because you are always selling one currency (the quote currency) to buy another (the base currency). The price of a forex pair is how much one unit of the base currency is worth in the quote currency.
