As a beginner, the duration of trading with a demo account varies for each individual, but it's generally recommended to use it until you feel consistently comfortable and profitable. A common guideline suggests spending at least a few months, allowing time to understand market dynamics, test strategies, and hone risk management skills. However, it's crucial to transition to live trading once a basic understanding is achieved, as real market conditions can present unique challenges. Balancing the use of a demo account with live trading experience helps bridge the gap between theory and practical application, fostering a well-rounded skill set for sustainable success in the financial markets.
