Having navigated the contract market for years, I have seen too many people get liquidated due to greed and fear. Today, I want to share three of the most profound lessons, which might help you avoid some detours.

**First: Protect the profits you’ve earned**

Many people always think about chasing the highest point, but in reality, this is the easiest way to get wrecked. After buying a coin that has risen 10%, it’s time to be alert—that’s a warning sign. If the price returns to your entry point, don’t hesitate; close the position immediately.

If it rises to 20%? Lock in half of the profits and let the rest run. Even if it eventually goes higher, you won’t regret it because you’ve secured gains. What if it reaches 30%? At least hold onto 15% profit. This isn’t being timid; it’s replacing feelings with discipline—and discipline is always more reliable than emotions.

**Second: Cut losses decisively**

This rule can save you countless times.

After entering a position, if it drops 15%, no matter how optimistic you are about this coin, stop loss immediately. You might say, “It really went up afterward”—what does that mean? It indicates you misjudged the rhythm, not that the opportunity itself was flawed. There are always opportunities in the market; the next wave is just ahead.

A position without stop loss protection isn’t trading; it’s gambling with your life.

**Third: Be willing to buy back after selling**

This is an often overlooked but crucial move. You close a position, and it actually drops back down, yet you still believe in it—then buy it back at the original price. The beauty of this approach is that your coin holdings don’t decrease, and your account actually gains more liquidity.

If you hesitate and don’t buy back, and the price rebounds again, don’t force it. Once it returns to your selling price, buy back unconditionally. Transaction fees are a small cost; the real loss is the regret of missing out.

**Final words**

Short-term trading isn’t about reckless chasing, and chasing hot topics isn’t about random hits. True experts in the market are often not because they can precisely buy the bottom and sell the top, but because they understand rhythm and have discipline. Those who survive long in this market are always those who can control their own fingers.
