The main purpose of Forex is to ease international trade and investment by enabling businesses to convert one currency into another with their rate. For example, if a company in the United States wants to buy goods from Europe, they may need to convert their dollars into euros to complete the transaction.

Forex trading predicts fluctuations in exchange rates between different currencies. Traders aim to profit from these fluctuations by buying a currency when its value is low and selling it when it appreciates. Exchange rates are influenced by various factors, including economic indicators, geopolitical events, interest rates, market sentiment, and more.
