This chart reveals a critical but often overlooked principle: "Breakthroughs shouldn't focus on shadows, only on closing prices."

1. Misconception: Shadow Breakthrough ≠ Valid Breakthrough

In the chart, you can see that the price repeatedly "pierced" key levels but never managed to close above them, ultimately retreating. This is a typical false breakthrough and the root cause of many people's losses from chasing highs.

2. Confirmation: Closing Entity > Shadow Probing

A truly trade-worthy signal must have the K-line entity firmly above the key level, indicating that capital recognizes and the price is stable. This structure is supported by the probability of "continuity" behind it.

3. Strategy: Waiting is not missing out, but filtering

Waiting for closing confirmation may seem conservative, but it is actually the core operational principle of filtering noise and avoiding false moves. In the early stages of a trend, missing out on a portion of the price increase is not regrettable; misjudging the direction once carries the greatest cost.
