Forex trading is the buying and selling of currencies in the global foreign exchange market. Traders aim to make profits by predicting changes in currency values such as USD, EUR, GBP, and JPY. The forex market operates 24 hours a day and is considered one of the largest financial markets in the world. Traders use charts, technical analysis, economic news, and trading platforms to make decisions. Forex trading can offer high profit opportunities, but it also involves significant risks due to market volatility and price fluctuations.
