Yesterday's trading decision taught me another lesson. Watching the daily K-line rebound from a low point, I chose to exit early. Although I didn't incur a loss, the profit was also significantly pulled back.

Looking back at the key points of the trend, it becomes clear: from a high of 40m down to yesterday's 10m peak, then probing the bottom at 4m, and now rebounding to 8m—that is, a market that can double in just one day with good news. What does this kind of double-up from a low position actually imply? The market's previous pricing was clearly overly pessimistic, and once expectations shift, the speed of the rebound can be rapid.

The problem is, when you're hesitant at the bottom, you often miss out on the biggest upward potential. This lesson isn't about stock picking, but about understanding market sentiment cycles—when to hold firm and when to escape. The balance between the two is always the greatest test of human nature.
