I found that the human brain is really biased: when there's a floating profit, it just considers it "as it should be," but floating losses, even if not sold, can cause you to toss and turn in your mind all night. The more you think about it, the more unwilling you become, and your heartbeat becomes more sensitive than the candlestick chart. To put it simply, it's not about how much you've lost, but the noise about "maybe I did something wrong" that bothers you the most.

Recently, I saw some news about tax increases and tightening/loosening of compliance. I actually react a bit slowly... My initial thought is "what does this have to do with me," but after a couple of days, I realize that when deposit and withdrawal expectations change, everyone becomes more anxious: afraid of giving back profits, afraid of not being able to get out of losses. Anyway, my current approach is pretty simple: keep smaller positions, prepare multiple strategies, and sleep better than chasing profits. That's how I’ll do it for now.
