Forex trading, or foreign exchange trading, involves buying and selling currencies in the global market to profit from exchange rate fluctuations. As the world's largest financial market, it operates 24/5, enabling currency conversion for international trade and investment. Participants range from major banks to individual traders. Factors influencing exchange rates include economic indicators, political events, and market sentiment. While offering profit opportunities, forex trading carries significant risks; proper education and risk management are crucial for success.
