Many traders have experienced a moment like this: they got the direction right, the entry point was good, and after holding for a while, they found themselves in profit. But as soon as there's a pullback, they panic and run.
You say your execution is poor? Ultimately, it's because you've never truly believed that you could capture the full profit from this wave. Your subconscious has long set a ceiling of 'I don't deserve to earn this much,' so whenever your profits reach this critical point, you rush to secure the gains, unable to even withstand the fluctuations.
You are not 'afraid of losing'; you are 'afraid of winning'—afraid of giving back profits, afraid of falling from paradise. So you self-punish in advance, giving up your rightful share of value.
True experts do not guess the direction correctly every time; they have the ability to hold on, endure, and finish strong when they see the right opportunity.
The ceiling on profits does not lie in the market or the situation, but in your heart.
