#数字货币市场洞察 I've known Lao Zhang for eight years. Three years ago, he was still delivering food and paying off his credit cards. Last week, he suddenly showed me his account balance—seven figures just sitting there. I was stunned and couldn't say a word for a long time.

Over the years, I've seen many people come and go in this space, but less than 10% actually make money. Lao Zhang, with his "simple methods," survived instead. You might think his approach is old-fashioned, but it really works.

**Lesson One: Don’t Stare at the Charts Aimlessly, Only Focus on Two Time Slots**

When he first got into trading, Lao Zhang was a typical retail investor—following group messages and chasing trades, which cost him over 40,000 in half a year. Then he did something simple: he printed out two years of candlestick charts and compared them one by one.

He ended up focusing on just two trading windows: from 3pm to 5pm, when the European and US markets overlap and there are fewer false signals. He prepares his plan in advance and only looks at the chart during that window. Last year, just trading in this timeframe brought him over 10% returns.

The other window is right after the monthly non-farm payroll data release. But he never jumps in at the first wave—he always waits ten minutes or so to see the direction clearly, then tests the waters with a small position. Last November, this approach earned him three months’ salary with a half-sized position.

**Lesson Two: Three Indicators Are Enough, Don’t Overcomplicate Things**

Lao Zhang’s charting software is incredibly simple, and he only pays attention to three things:

- Bollinger Bands touching the lower band three times, with increasing volume each time—a sign of an upcoming rebound.
- RSI climbing from the 30s past the 50 mark—trend reversal.
- Price moving sideways while OBV quietly rises—someone is accumulating.

When all three signals appear together, that’s when he considers entering. Last year, he caught a 30% price rally just using this.

**Lesson Three: Take Profits First**

He has a strict rule: once his profit reaches 50%, he sells half, and sets a trailing stop for the rest—using the most recent low as protection, holding as long as it doesn’t break.

The benefit is that, even if there’s a pullback later, he only makes less profit, but his principal and basic profit are already locked in. This keeps his mindset steady, so his decisions don’t get distorted.

The market is always there, but few people can survive it. You can try Lao Zhang’s "simple methods." At the very least, it won’t send you back to square one overnight.
