At three in the morning, the phone suddenly vibrated uncontrollably. I opened my eyes and saw it was a video call.

Connecting, there is a girl on the screen, her eyes red from crying, her voice trembling: It's over, it's over, my account with 6500U has completely exploded...

She spoke incoherently: "I opened a 6x short position with a full margin, who knew the market would suddenly reverse and it went up by more than two points, and just like that, the money is gone! What should I do now?"

Let her send over the transaction screenshot, and I was stunned when I saw it — 6300U directly all-in, stop-loss? Not a thing.

Many people think that using the entire margin is equivalent to quickly doubling their investment, but the truth is: using the entire margin is like driving a car without brakes; if the steering wheel is slightly off, it could directly lead to a crash off a cliff.

I've seen this kind of thing too many times. The market fluctuates just a couple of points, and the account instantly goes to zero, not even giving you time to react.

When I first entered the circle, I also paid a lot of tuition. Later, I explored a few survival rules for full position trading, and after strictly following them, not only did I preserve my capital, but my account also steadily grew by over 70%.

These experiences are not complicated to talk about, but each one was earned with real money. Later, I will write a dedicated article to explain these methods in detail, which can at least help you avoid 90% of the liquidation traps.
