Recently reviewing my past records, many losses weren't due to poor judgment, but because I kept waiting: waiting for confirmation, waiting for a pullback, waiting to think things through. The more I waited, the more it felt like dragging out a breakup without saying it clearly, with transaction fees and opportunity costs slowly eating away, and my mindset also getting worn down. To put it simply, stop-loss is about admitting a mistake, not giving up. Now I write down the "maximum amount I can tolerate" in my chart in advance, and when triggered, I execute without negotiating with myself. As for the interpretation of ETF capital flows and U.S. stock risk appetite, I also glance at them, but when it comes to placing an order, I still follow my own rules, or I’ll start waiting again... Anyway, for now, that’s how I’ll do it.
