At two o'clock in the morning, my phone kept ringing. A friend from Jiangxi kept sending voice messages, sounding panicked:

“Hey, I put 10,000 U in full margin with 10x leverage, and it just corrected by 3%, and now the money is gone. What happened?”

I opened his trading records and saw he went all in with 9,500 U, without even setting a stop loss.

Many people mistakenly believe that “full margin = can withstand it,” but in fact, it is quite the opposite—using full margin improperly leads to faster losses than using partial margin.

1. The key to full margin liquidation: it’s not leverage, it’s position weight

Take a 1,000 U account as an example:

If you use 900 U with 10x leverage, a 5% adverse movement will wipe you out;

But if you use 100 U with 10x leverage, you need a 50% movement to be liquidated.

My friend put in 95% of his capital with 10x leverage, and a slight correction wiped him out.

2. Three principles that allowed me to use full margin for six months without liquidation and double my money

1. Single trades should not exceed 20% of total capital

For a 10,000 U account, the maximum amount to invest at one time is 2,000 U.

Even if the direction is wrong and you set a stop loss at 10%, you only lose 200 U, which doesn’t hurt your capital, and you can recover at any time.

2. Single losses must not exceed 3% of total margin

For example, if you use 2,000 U with 10x leverage, set a stop loss at 1.5% in advance, a loss of 300 U is exactly 3% of total capital.

Even if you make several mistakes, it won’t cause significant damage.

3. Don’t open positions during fluctuations, and don’t add to profits

Only trade during trend breakouts; even if sideways trading looks tempting, stay on the sidelines;

Once a position is opened, never chase the price, and avoid emotional interference.

3. The true use of full margin: it’s a buffer, not gambling

The original intention of full margin is to leave room for error in volatility, but the premise must be light positions for trial and strict risk control.

Previously, a fan kept experiencing liquidations monthly, but after following these three rules, he increased from 5,000 U to 8,000 U in three months.

He said: “I used to think full margin was gambling with my life; now I understand that full margin is about living more steadily.”
