I know the reason, but I won't tell you

Brothers $ETH , can I ask what the principle of pin insertion is? It's hard to defend against. The overall direction may be right, but I keep getting stopped out by a sudden move. The main issue is that no matter how large the stop-loss point is, it can still be hit. Then I watch the trend move in the expected direction and get really frustrated. At first, I had a 20% stop-loss, now it's 80%, and I can still get wiped out several times.
