I set a 3210 stop loss before bed, watching the liquidation price at 4500, thinking it’s impossible to hit that level. A thought flashed through my mind—since it’s still far away, I’ll just cancel the stop loss.

Woke up around 5 a.m., probably because I didn’t sleep well after holding the position overnight, so I casually checked my phone. 3215. Luckily, it’s still okay, just hold on, and it should rebound at dawn. But when I looked at it in the morning—3320? What the hell. Without any hesitation, I immediately closed all positions with a single click.

The biggest lesson in trading is: stop loss must be strictly enforced. It’s not just about setting a stop loss and calling it a day; the key is whether you can really press the button when the market reaches that point. Lucky psychology dies the fastest in this market. This time, I was slapped in the face by my own words—"impossible."
