I'm really regretting not closing my position earlier. At that time, my profit had already risen to $130, but I just watched it slip away. Greed is truly the biggest enemy in trading. The market was clearly signaling me to take action, but I didn't listen. Fortunately, I still closed the position with a profit, which is better than a loss. To be honest, this operation taught me a lesson — sometimes it's more important to cut losses early than to chase the maximum profit. If I get another chance like this next time, I definitely won't make the same mistake again.
