In the market, the repeated stalling of many traders is not due to "lack of technical skills" or "emotional breakdown."

But there is a more covert and harder-to-detect obstacle dominating you: inertia. It's not that you don't know what's right, but rather that your "old ways" are too powerful.
Inertia: It makes you repeatedly return to the starting point that you clearly know:
Stop-loss must be executed, and cannot resist the order;
Profits need to be increased, and cannot be shrunk.
Opportunities must be awaited, do not act impulsively.
But in practice, whenever there is market volatility, one subconsciously feels the urge to "do something":
Clearly should wait for the signal, but placed an order early; clearly should reduce positions, but want to gamble once.
Clearly, it should follow the system, but instead it temporarily "creates" its own logic... This is not about not understanding, but being led by the reactions that one has "gotten used to".
The most terrifying aspect of inertia is that you are completely unaware that it is leading you — you think it is "judgment," but in fact it is "old patterns."
