#美联储恢复降息进程 Why do contracts always explode? Most people's first reaction is that the market is too crazy, but the truth is heartbreaking: the mine was buried by yourself.

I've seen the same script countless times—when the market fluctuates slightly, people panic, open positions recklessly, leverage to the max, and keep telling themselves, "This time I'll definitely break even." In the end, their accounts are wiped out, and they blame the market. But to be honest, liquidation has never been a matter of luck; it's because you didn't understand the rules of the game at all.

**Let me start with an counterintuitive fact: leverage itself is not a bomb**

100x leverage sounds scary? With a 1% position, the risk is actually manageable.
On the contrary, a 10x leverage looks safe, but would you dare to go all in with 50%? That's just waiting to die.

The real risk formula is simple: **Actual Risk = Leverage Ratio × Position Size**.

This thing is like driving; speed isn't scary, what's scary is speeding with your eyes closed. The first lesson in contract trading isn't predicting the market, it's learning to hit the brakes.

**The dumbest perception I've seen regarding stop loss is "stop loss = admitting defeat"**

During the crash on March 12, nearly 80% of the liquidated accounts had no stop-loss set. Why? Because they thought, "Just wait a little longer; it might come back." In the end, the market does not give you a second chance.

The professional approach is: **Control single loss within 2% of the principal**.

It's like the fuse of a house; it's better to blow one than to have the whole building catch fire. Stop-loss isn't about fearing loss; it's about ensuring you still have chips left on the table.

**Rolling over positions ≠ All in, compound interest is the core weapon**

Many people misunderstand "rolling positions", thinking it's an all-in bet. The true logic of rolling positions is:
Small position trial order → Made a profit → Use **profit** to increase the position, not to hard leverage with the principal.

There is a risk control formula that can be memorized:
**Maximum Position = $ETH Principal × 2%( ÷ ) Stop Loss Percentage × Leverage Multiple(**

For example: with a principal of 50,000, a stop loss set at 2%, and a leverage of 10 times, your maximum position size would be 5,000.

What to do when you're in profit? Take profit in batches:
- Up 20%, first liquidate 1/3
- Up 50%, rebalance 1/3
- Set a trailing stop loss; withdraw if it falls below the 5-day moving average.

Steady, accurate, and ruthless. These six words are the survival principles of professional players.

**The three traps that beginners are most likely to fall into, and one is basically doomed**

1. **Holding a position for over 4 hours** → Liquidation probability 92%
2. **500 high-frequency orders per month** → Transaction fees directly consume a quarter of the profit
3. **Not understanding profit-taking** → 83% of people will give back all the profits they have made.

I've seen too many people with a paper profit of 50%, unwilling to leave, and in the end, the market reverses, and they lose even their principal. The cost of greed is always more expensive than you imagine.

**The essence of trading is not an emotional battle, but a mathematical game**

There is a formula called "expected profit value":
**Profit Expectation = ) Winning Rate × Average Profit ( - ) Losing Rate × Average Loss (**

Achieve these three points:
- Stop loss 2%
- Take profit 20%
- The win rate only needs to reach 34%

You can achieve stable profits. Professional traders never rely on guessing the direction to make money; they rely on making mathematics sustainable.

**Lastly, a few iron rules: those who truly make money are quietly executing them.**

- Single loss ≤2%
- No more than 20 high-quality trades in a year
- Profit and loss ratio ≥ 3:1
- 70% of the time is spent waiting in cash

The market is always about probabilities; your task is to manage risk. Keep your losses under control, and profits will grow on their own. Stop asking "why did it explode again," and ask yourself if you followed the rules.
