Foreign exchange, often abbreviated as forex or FX, refers to the global marketplace for trading national currencies against one another. It involves the conversion of one currency into another for various purposes, including commerce, trading, and tourism, and is characterized by a decentralized market where currency trading occurs over-the-counter (OTC) rather than on a centralized exchange.
