I just recently figured out how to draw trend lines for analysis, and as soon as I turned around, I validated it on a coin. After breaking through its previous range, this coin looks like it’s about to surge upward in one go. I was holding a short position at the time, thinking I could withstand the pain. But the market taught me a lesson—within about 15 minutes, it suddenly spiked down to 0.055. At that moment, I almost thought I was being fueled for a burn. Luckily, I reacted quickly and exited during the pullback. Looking back now, although this loss burned my tongue, it was also the most vivid stop-loss lesson I’ve had. It seems that technical analysis is just the foundation; the real skills lie in risk control and disciplined execution.
