Today I hit a snag and want to share this harsh lesson.

This morning, I saw a shrinking volume signal on the 15-minute K-line and impulsively thought the price would drop, so I opened a short position. I completely overlooked that the price was still in an upward channel—smart money monitoring data showed large funds entering the market, whales eating up chips. Plus, this coin was participating in a trading competition, and the hype was there, but I ignored it.

Even more ridiculous was that I used too high leverage. When transferring funds into the margin account, the system credited the full amount directly, but I found I couldn’t reduce the margin—only increase it continuously, and I was stuck for a long time before I finally got out.

The biggest takeaway is realizing a serious flaw: you must reserve enough backup funds in your account. This way, even if your position fluctuates, you have a buffer and won’t be forced to liquidation. Next time I open a position, I need to calculate this amount beforehand and avoid letting funds get stuck in the margin without any movement.
