This morning watching the sea, the waves come and go, I suddenly thought that my trading is just like that: I can't hold onto spot positions, and when I get into contracts I get excited and want to "hold on a little longer"... and then I get educated. To put it plainly, position management boils down to one thing: first set aside the part you can survive with, only then can you talk about "opportunities."

Now I set three "stops" for myself: stop (if I get impulsive to add, I first close the software and go get a glass of water), stop and watch (don't stare at the one-minute K-line and mess up my heartbeat), stop and refresh (there are a bunch of emotional outputs in the group, too much scrolling makes me want to gamble).
Recently, hardware wallets are out of stock, phishing links are rampant, and the more these happen, the slower I need to be—don't rush to click confirm.
Conclusion: only the positions that let you sleep well are your true positions.
