In the early morning of December 2017, I stared at the numbers beating on the screen, my hands shaking.

Three minutes - in just three minutes, the account went from six digits to 37.28U.

The first time I touched the contract, it taught me a lesson. Sitting in the dark, the heartbeat sounded like a broken gong, one by one, very loud.

Ten years have passed. From that 37.28U to the current seven-figure number, my biggest realization is not how to earn, but how to survive. The contract is not a gambling table, but more like an operating table - every knife has to be counted.

**About positions: Don't put your life on it**

I have a dead rule: a single loss should never exceed 1% of the total funds.

Sound intimidating? On May 19, 2021, the market collapsed, and countless people around me exploded directly, and my account retraced by up to 12%. How to calculate? Suppose you have 10,000U and the stop loss is set at 10% of the current price, then the position is controlled at about 100U (10,000×1%÷10%). This is not a math problem, it is a living proposition.

A conservative point is better than zero.

**About stop loss: don't tell yourself the conditions**

I've seen too many people - the price falls, the stop loss moves down; Fall again, move again; In the end, there was no way to retreat.

My stop loss is set to be a piece of iron. Either the price hits it and stops, or I hit it out. There is no "observe for a while", there is no "maybe it can rebound". Wrong is wrong, admitting cowardice is 10,000 times better than carrying death.

**About Leverage: It's Your Vulnerability that Amplifies It**

Many people think that high leverage amplifies returns. Wrong, it magnifies every small flaw in your strategy.

I use 3-5 times all year round, and the maximum is not more than 10 times. Why? Because more than 10 times, the market normally fluctuates by 3-5%, and you may be liquidated. At this time, you are not trading trends, but market noise.

You're fighting the air.

Over the years, I have seen screenshots of liquidations at four o'clock in the morning, and I have also seen the madness of having more than two zero accounts after getting rich overnight. But what the market leaves in the end is never the smartest or most ruthless people, but the people who know how to "restrain" the most.

Do not carry a single order.
No stud.
I don't believe "this time is different".
Don't double down on your money when you lose money.

In the contract market, to live is to win. Those thrilling stories will fade away, but your account balance will remember everything.

Ten years later, I still remember the early morning of 37.28U - it taught me not how to win, but how not to lose.
