The Role of Trading Emotion Varies by Stage:

In the novice stage, one should focus on refining mechanical trading strategies, with clear rules and disciplined execution; emotions are a distraction;

During the period of excessive trading, emotions can easily spiral out of control amidst profit and loss fluctuations, hindering rational analysis;

Mature traders, on the other hand, convert emotions into a part of their strategy and risk management, going with the trend.

Those who emphasize 'emotion management' in the early stages often lack capital and have no well-formed strategy.
