Early in the morning, my phone kept vibrating nonstop. On the video call, a trader from Zhejiang looked upset: "My 6000U account is gone... Fully leveraged with a 5x position, just a 3-point pullback and it blew up."

Looking back at the trading records, I saw that he had put all 5800U into the position without even setting a stop-loss. These kinds of mistakes happen all the time.

Many people have a misconception that full position equals quick profits. In reality, it's the exact opposite—full leverage is like driving a car without brakes; a slight misdirection and it becomes scrap metal.

The real culprit behind liquidation isn't the leverage itself, but the size of the position.

For example, consider this calculation: with an 800U account, using 750U to open a 5x position, a 6% adverse move would wipe out the account; but if only 75U is used to open the same 5x position, it would take an 86.7% move to lose everything. The risk resistance is nearly 12 times lower. She had put 96.7% of her principal into the trade, and just a small pullback with 5x leverage couldn't hold—this isn't about gambling, it's playing with fire.

Over the past year, I've stepped into many pits and gradually summarized three survival rules. Not only did I avoid losing my principal, but my account also steadily grew by nearly 80%:

**First Rule: Only use 7% of total funds per trade**

For a 6000U account, the maximum per trade is 420U. Even if the 7% stop-loss is triggered, the loss is only 29.4U, which doesn't affect the overall situation. Losses are controllable, and the mindset remains stable.

**Second Rule: No single loss exceeds 1.1% of total funds**

Using the same 420U with 5x leverage, set a 1% stop-loss in advance. If hit, the actual loss is 8.4U, about 1.1% of total funds. Close the position immediately to avoid deep entrapment. Stop-loss is engineering, not philosophy.

**Third Rule: If you can't see clearly, stay out of the market. Don't chase the rally, just wait for confirmation**

When the market is unclear, stay disciplined and rest. Don't add to positions just because you've made some profit earlier. Wait until the daily chart truly breaks key levels and volume confirms. Enter only then. Better to be slow than to gamble recklessly.

A follower used to blow up his account every month, but after applying these three rules, over four months, he grew from 3,200U to 55,000U. He later told me: "I used to think full position was gambling my life away. Now I understand—true full position is about surviving longer."
