Currency trading, also known as forex or FX trading, refers to the buying and selling of different currencies in order to make a profit. It involves speculating on whether the value of one currency will increase relative to another currency. Currencies are traded in pairs, with the price of each pair determined by supply and demand forces on the market. Traders use various strategies and techniques to predict movements in exchange rates and make money from their trades. The forex market is the largest financial market in the world, with an average daily volume of over $5 trillion. It operates 24 hours a day, five days a week, making it accessible to traders at any time.
