Forex trading involves buying or selling foreign currency in various international transactions, including holiday spending and foreign goods. The vast volume of forex trading includes businesses and central banks of governments, with trillions of dollars in investment swapped around the world every second. The need to calculate and set the value of currencies in relation to each other, regardless of local economic factors or trade patterns, drives this activity. Unlike stocks, forex trading takes place in a decentralized, around-the-clock market composed of various interbank trading locations. The market is open 24/5, attracting retail traders and institutional traders.
