The day I understood the meaning of a margin call liquidation and wiping out everything, I realized the money I made was never earned by real skill. $SNDK

Eight years ago when I first entered the market, I had only a few tens of thousands in capital. A great行情 (market opportunity) came along—everything I bought went up. After making a few profitable trades, I got overconfident and thought I had figured out the pattern.

Until one time a margin call wiped my account to zero, and I finally learned that my previous “experience” couldn’t survive an actual stress test.

When I started over, I didn’t have many chips left. The first thing I did was quit going all-in. With small capital, I only touch the situations I truly understand. If I can’t afford to stay flat for a day, that’s fine—I just secure part of the profit when I reach my target, and I don’t greedily squeeze out that last bit. When major news drops, during long holidays, or if trading volume suddenly spikes in the middle of the night, I proactively reduce my position. If good news starts to weaken, I cash out and leave—no holding on to a losing position forever.

For the medium- to long-term, I’m afraid that too heavy a position won’t be able to withstand the oscillations. For the short-term, I wait for the right level and the right signal, then execute when it’s at the point. #AMD市值首破1万亿美元

Over the years, these habits formed: after a sharp rise followed by weakness, don’t chase. After a sharp drop followed by an ineffective rebound, don’t try to guess the bottom. If I’m wrong, I admit it—cutting losses is just keeping the mistake contained within that single trade.

Later I understood this too: the most expensive tuition in trading isn’t how much you lose—it’s losing everything and still not knowing why you lost. Technical analysis can help you find opportunities, but what determines how long your account can last is whether, at the moments you feel like doing something reckless, you can pull your hands back in time.
