Forex trading success is often attributed to having the right mindset, with 90% of success dependent on this and only 10% on the trading system itself. This means that traders should focus on developing a positive attitude, discipline, patience, and a willingness to learn and adapt. It's important to manage emotions, such as fear and greed, and approach trading with a clear and objective mind. While a good trading system can help, it's the mindset that ultimately drives success in forex trading. Traders who prioritize mindset and personal growth tend to be more resilient, consistent, and successful in the long run.
