A realistic target for a beginner trader in the forex trading business would be to start off with a small trading account, and aim to make a consistent, steady return of 10-20% per year. This could be achieved by having a risk management system in place and following a well-defined trading plan. A beginner trader should also focus on learning and understanding the basics of forex trading such as reading charts, reading market news, and understanding the psychology of the markets. Having a good understanding of the markets and how the different currencies are affected by news and economic data can help a beginner trader make more informed trading decisions. Additionally, the more experience a trader has, the better they will be able to develop their risk management and trading plan, which will lead to higher returns over time. Finally, a beginner trader should have realistic expectations, and not expect to become a millionaire overnight. It takes time, patience, and dedication to become a successful trader, and having realistic targets will help you stay on track and avoid any costly mistakes.
