A truly useful trading discipline is often more reliable than any flashy strategy.

Five years ago, I was still struggling in the quagmire of margin calls; today, my account has achieved relatively stable growth. This transformation didn't come from cracking some mysterious code; frankly, it was about spending enough time to refine my own trading system.

What I want to share today is not some get-rich-quick scheme. I want to discuss how, in this 24/7 roaring crypto market, you can both preserve your principal and steadily accumulate profits. The "15-minute three-dimensional resonance strategy" I developed has helped me find a stable rhythm amid the fluctuations of ETH and other mainstream coins.

**Why did I finally choose the 15-minute chart?**

Many beginners prefer 1-minute or 5-minute K-line charts, for simple reasons—more signals, more opportunities. But the reality is, the shorter the cycle, the more noise there is. I used to place over 20 trades in a day on the 5-minute chart; what was the result? Most of the profit was eaten up by fees, and my mindset was tossed around by false signals.

The 15-minute chart finds that balance point. It doesn't produce the ear-splitting noise of minute-level charts, nor does it react sluggishly like the 4-hour chart. For most people, scanning the K-line every one or two hours is enough to catch sufficient opportunities.

More importantly, technical indicators like MACD and moving averages only generate truly stable signals at the 15-minute level. The number of candles is enough, and the probability of false signals naturally decreases.

**The core logic of "Three-Dimensional Resonance"**

The key to this method is: don't trust a single signal. I require all three dimensions to point in the same direction before confirming a trading opportunity. This is what I call "Three-Dimensional Resonance."

The first dimension is price structure—identifying support and resistance levels. The second is momentum indicators—cooperation between MACD and moving averages. The third is volume—confirming the authenticity of the trend. When all three align, that’s the true entry signal.

Using this disciplined approach to trading, although opportunities may seem fewer, each one is more solid. That’s how I evolved from a trader who frequently blew up accounts to someone who now experiences relatively stable growth.
