At 3 a.m., how many tired faces are illuminated by the glow of the screen? The numbers in the account are slowly evaporating—from five figures down to four, then to just a few thousand dollars. That process from hope to despair is more heartbreaking than any thriller novel. Sister Bing endured it this way.

Many people think that a mysterious K-line pattern or some advanced indicator is the life-saving straw. Actually, it’s not. What truly changed her were a few simple trading disciplines—so straightforward they can't be simpler—that she gradually solidified through countless cuts and regrets.

**First Rule: Only trade at positions you truly understand**

The market is moving 24 hours a day, opportunities are plentiful. But once the principal is gone, it’s really gone. Sister Bing quit the addiction to "fearing missing out on the trend"—no longer blindly chasing rallies. She only enters trades decisively within pre-planned zones. At other times, even if her fingers are already on the keyboard, she restrains herself. Once, ETH experienced extremely wild fluctuations. A bunch of fans wanted to chase the high, but she insisted on waiting for a pullback to the target zone before opening positions. As a result, she secured future gains steadily and avoided pitfalls. Waiting for her own signals is much more reliable than following the herd.

**Second Rule: Survival always comes first**

Before opening a position, shift your mindset: don’t focus first on how much you can earn, but precisely calculate how much you could lose in the worst case. With proper position sizing, you can withstand market volatility and wait for the next opportunity.

**Third Rule: Take profits in stages**

When the market rises, she splits her holdings into two parts: one continues to chase the trend, the other is partially cashed out at key resistance levels. The advantage of this approach is participation during gains and protection during downturns—never risking everything.

**Fourth Rule: Stop trading without signals**

Feelings and excitement can never replace trading rules. As long as the conditions haven't appeared, no matter how itchy your fingers are, you can't make reckless moves. Waiting itself is the highest form of strategy.

With these four simple rules, she transformed from someone who was led by the market's whims into an ordinary trader following her plan. Her profit curve fluctuated wildly at first but gradually stabilized. Most importantly, those late-night candlesticks no longer hijack her sleep—she used to stumble in the dark, now she carries a small light, not very bright, but enough to illuminate her path.
