Having been involved in this circle for nearly ten years, I went from a rookie trembling while placing an order with just 60,000 yuan (still borrowed from relatives) to becoming someone others see as an "old hand." My account size has multiplied several times, but more valuable are the blood lessons learned along the way.

I've seen too many stories. Some have traded up to hundreds of millions, riding high, only to hold on stubbornly during a market downturn until liquidation, falling from heaven to hell overnight. Many others take a different path — the more they lose, the more anxious they become; the more anxious, the more chaotic; the chaos leads to even bigger losses. In the end, they are not defeated by the market but by their own temper.

They are not lacking in analytical ability. Where is the problem? It’s that stubbornness. Thinking their judgment is correct, they insist on "trying one more time" to turn the tide, only to dig themselves into an even deeper hole. The market will never listen to your explanations; whether your analysis is right or wrong, it simply doesn’t care.

Here are a few simple rules I’ve figured out that have kept me going until today.

**Rule 1: Cut losses quickly, never fight the market**

In my early years, I also suffered from stubbornly holding on. Later, I realized a truth — arguing with the market is the stupidest thing in the world. You think it will go up, but the market refuses to cooperate; you judge it’s a trap to lure more buyers, but it simply doesn’t care about your judgment.

Now I do it very decisively: set a stop-loss before opening a position, and exit when the time comes. Don’t try to reason with the market; the rules are right there. This way, I can survive longer and earn more steadily.
