While focusing on a few currency pairs can enhance your expertise, diversification helps reduce risk. Instead of trading just EUR/USD, consider adding pairs like USD/JPY or GBP/AUD to balance your portfolio. Diversification also applies to strategies; mix short-term techniques like scalping with long-term ones like swing trading. By spreading your risk across different currencies and methods, you’re better prepared for unpredictable market conditions. Remember, diversification isn’t about trading everything—it’s about finding the right balance for your style.
