Emotions can really mess with our trading decisions, especially when we see those red and green candlesticks. When we're in the red zone, fear can make us miss good chances by holding onto losing stocks for too long. And when we're in the green zone, overconfidence can make us wait too long to sell and miss out on big profits. It's crucial to understand market cycles, stick to trading rules, and keep emotions in check to make wise decisions. Trading is all about staying calm and making smart moves.
