Whenever real money is used for trading or participating in battles, without exception, there is always emotion involved, and there are times when traders resist closing positions; because we are human, and as humans, we have emotions. We can only try to minimize them and cannot eliminate them completely; the difference between ordinary people and excellent traders (such as Guilin) lies in how to minimize losses when making mistakes (for example, opening long ETH positions at 3700 to resist the market) and then avoid making the same mistake in the short term.
