Understanding starts with reducing trading frequency. Everyone knows to wait for the right opportunity, but it's hard to do so. The market data fluctuates back and forth, seeming to present too many opportunities to make money. It feels like a waste not to jump in and grab some, but once you do, you end up trapped. Once trapped, your mind gets chaotic, and you can't focus on trading rules, let alone wait for the right moment. Your head is filled with negative emotions brought by being trapped, leaving no room to think about anything else. This is usually how losses happen.
