A successful ambush was executed at the 600k level. Speaking of this, the ambush strategy is actually a game of probability—you set up positions in multiple places, and some will hit the right rhythm. Instead of worrying about whether you can precisely bottom fish, it's better to cast a wide net and deploy defenses at multiple points. Sometimes you're ambushed by the market, and sometimes you successfully ambush others—that's the normal state of trading. The key is to keep a steady mindset and not be swayed by the ups and downs of a single position.
