I took a stroll around the square, and everywhere I looked, there were all these investment return rates—-300%, -500%, even -1500% from those anti-liquidation warriors. Aren't they all shouting 'cut losses quickly', 'align knowledge with action', and 'always set a stop-loss when opening a position'? So why is it so hard to actually do it when it comes to your own trades? It's tough! Really tough! Until you feel the pain yourself, you can always talk big.
