As for me, the main advantage of trading by intuition is the speed of decision making. Guided by intuition, I spend several times less time and effort to analyze the situation. Of course, this is not always an advantage, because if a trader is a beginner, intuition can deceive him. But for me, intuitive solutions are a great way to save time without losing efficiency.
The second advantage is that I become more confident when listening to my intuition. Although the analysis and application of successful strategies can give a positive result on their own, when an intuitive solution supports them, a trader learns to really feel the market.
