I found that what affects my sleep the most isn't missing a trade, but that little floating loss that stays there. When I'm in a profit, I think, "It's not in my pocket yet, I can always give it back," and the more I look at it, the more I want to take more; floating loss is different, my mind automatically treats it as "I've already lost," even if it's just price fluctuations, I can't help but want to wipe it out mentally. To put it simply, the pain of losing is much greater than the pleasure of winning.

Recently, someone also interpreted ETF capital flows, U.S. stock risk appetite, and crypto market rises and falls together, looking at a bunch of emotional speculations. I also feel a bit envious of those who can just go all-in and then sleep well... but with my market-making/placing orders approach, what I fear most is being led by emotions to change parameters. Now I give myself a simple trick: when floating loss exceeds a certain slippage threshold, reduce positions/hedge, don't expect to "wait for a rebound to recover"; floating profit is even more mechanical—once it hits the preset range, take some off in batches, and before sleeping, look at the market a couple less times. It really saves a lot of mental energy. That's it for now.
