#美国就业数据表现强劲超出预期 woke up in the early morning to a distress call from a friend. The guy from Guangdong sounded noticeably overwhelmed: he had $10,000 in his account, fully leveraged with over 10x long positions, and as a result, the market just pulled back 3%, instantly wiping out his principal.

I looked at his trading record — he had put in all $9,500 without even setting a stop-loss. That’s a classic case of poor position management. Many people misunderstand this: full position ≠ stability. In fact, it’s more likely to lead to suicidal liquidation.

The key issue isn’t the leverage number but the size of the position. To put it simply: with a $1,000 account, using $900 to open a 10x leverage position, a 5% adverse move can wipe you out completely. But if you only use $100 to open a 10x position, it takes a 50% move to trigger liquidation. My friend put 95% of his principal all in at once, and a slight shake was enough to break him.

So what’s the solution? I’ve summarized three principles, which I’ve been following for half a year now. I haven’t blown up my account and even doubled my capital:

**Principle 1: No single trade exceeds 20% of total funds**
With a $10,000 account, never risk more than $2,000 at once. Even if you’re wrong and set a 10% stop-loss, you only lose $200, which is 2% of your total capital. This doesn’t damage the core funds and leaves room to recover.

**Principle 2: Limit single-loss to within 3%**
Using $2,000 to open a 10x position, set your stop-loss at 1.5%, so the maximum loss is $300. Even if you make a few wrong trades, it won’t wipe you out.

**Principle 3: Observe during consolidation, act during profit**
Only enter the market when the trend is confirmed. During sideways consolidation, no matter how tempting, don’t trade. Once in, never chase positions. Don’t let emotions override your discipline.

The true meaning of full position isn’t gambling everything, but leaving yourself buffer space. Its original purpose is to seize more breathing room amid volatility, but only if you start with a light position and strict risk control.

There was a friend before who kept blowing up his account every month. After adopting this method, in three months he went from $5,000 to $8,000. He said himself: “I used to think full position was for big bets, but now I realize it’s for staying alive and making money.”

Consistent trading isn’t achieved overnight. It’s the accumulation of details that allows you to go further.
