#TradingStrategyMistakes > I’ve made many mistakes while trading. My biggest one was trading without a stop-loss, which led to huge losses. Another was overtrading out of greed or fear. I also used high leverage without understanding risk, which wiped out my account. I learned that emotional control is more important than technical knowledge. Now I always plan my trade, use stop-loss, and manage risk. Keeping a journal of my trades helps track what works. Learning from mistakes made me a better trader. #TradingStrategyMistakes
