In the early hours, an anxious voice call came through. The other party is a friend who has been trading for years, and his voice was clearly panicked—"Bro, I put my 10,000 yuan account all in with 10x leverage long, and the market just retraced 3 points, and my money is gone. What’s going on?"

I quickly pulled up his trading records and frowned immediately. All 9,500 yuan was in the position, with no stop-loss set. That’s really bold.

Many people have a misconception that full position can help resist risk. Actually, it’s the opposite. Full position is a double-edged sword; if used poorly, you can lose even faster than with partial positions. The problem isn’t leverage multiple, but the size of the position.

For example, a 1,000 yuan account, with 900 yuan used at 10x leverage. As long as the market moves 5% against the position, the account will blow up. But if only 100 yuan is used at 10x, the market needs to move 50% to blow up. My friend just pressed 95% of his principal into the position, and with 10x leverage, a small retracement was enough to wipe him out.

So how to use full position without getting liquidated? I’ve come up with three principles. Following these for over half a year, I not only never got liquidated but also doubled my account.

**First: Use only 20% of total funds per trade.** For a 10,000 yuan account, invest at most 2,000 yuan per trade. Even if you’re wrong and set a 10% stop-loss, you only lose 200 yuan, which doesn’t hurt the principal much and leaves room for reaction.

**Second: Never lose more than 3% of total funds on a single trade.** For example, with 2,000 yuan at 10x leverage, set the stop-loss at 1.5%. A 1.5% loss is 30 yuan, but with leverage, that’s 300 yuan, which is 3% of the total funds. Even a few wrong trades won’t damage your core capital.

**Third: Don’t trade in sideways markets, and don’t add positions when profitable.** Only enter when the trend clearly breaks out. Don’t trade during consolidation, no matter how tempting. After entering, never chase positions to avoid emotional trading.

The real way to use full position isn’t about betting on the direction, but about leaving buffer space. Its original purpose is to give you more breathing room amid volatility. But the premise is to trade lightly, with strict risk control.

Some followers kept blowing up their accounts month after month, but after following these three principles, in three months, their accounts grew from 5,000 to 8,000 yuan. One of them told me, "I used to think full position was just gambling big. Now I realize, full position is actually about staying alive steadily."

That makes perfect sense. Trading is most dangerous when you wake up one day and find everything gone. Staying safe and surviving in the market, turning time into compound interest, is the real skill.
