One a.m., a friend from Sichuan asked me tremblingly:

"Sophie, I went all-in with 10,000 U and opened over 40x leverage. It only dropped 3%, why did I get liquidated?"

I looked at his record, and he had put all 9,000 U in without setting any stop-loss.

Many people think that going all-in means "holding out," but in fact, if you don't use it properly, going all-in can lead to faster ruin than incremental positions.

The key to liquidation often isn't the leverage level but the size of the position.

Think about it: with a 10,000 U account, if you use 9,000 U to open a position,

a slight reverse move can wipe you out instantly.

But if you only use 1,000 U to open, the price would have to move 50% against you to get liquidated—it's a completely different concept.

I've been using full positions for over half a year without getting liquidated, and I've even doubled my money, relying on three principles:

First, never risk more than 20% of your total funds on a single trade.

With a 10,000 U account, never invest more than 2,000 U at once.

Even if you get the stop-loss wrong and lose 10%, that's only 200 U, which doesn't hurt your overall capital.

Second, never lose more than 3% of your total position on a single trade.

For example, if you open a 2,000 U position with 10x leverage, I set a stop-loss at 1.5%, which is exactly a 300 U loss, or 3% of total funds.

Even if you make a few wrong calls, your account can still withstand it.

Third, avoid opening positions in choppy markets, and don't add to your position after profits.

I only trade when there's a clear breakout trend; sideways markets, no matter how tempting, are off-limits.

After opening a position, never add more just because the price rises—maintaining discipline is the most important.

The original purpose of full-position trading is to give you room for error, not to gamble your life.

There was a fan who kept getting liquidated every month, but after following these three principles, he turned 5,000 U into 8,000 U in three months.

He said, "I used to think full-position trading was gambling, but now I understand."

Using full positions correctly is about staying safer.

In this market, surviving is always more important than chasing quick profits.

Reduce risky bets, control your position size, and remember: slow is fast.

If you always find it hard to control yourself, the guiding light is right in front of you—just follow it. @Professional Trading~Sasha
