For beginners in forex trading, it's recommended to start with major currency pairs, which are more liquid and have lower spreads. The most popular and commonly traded pairs include EUR/USD, USD/JPY, GBP/USD, and USD/CHF. These pairs offer ample liquidity, tighter spreads, and more predictable price movements. They also provide a wealth of information and analysis due to their popularity. However, it's important for beginners to focus on learning and understanding the dynamics of a few currency pairs rather than spreading themselves too thin. As proficiency and experience grow, traders can explore other currency pairs and exotic crosses. Remember, thorough research, practice, and continuous learning are crucial for successful trading, regardless of the currency pair chosen.
