We must analyze the market in real-time and make predictions (very important), set a trading plan, and as long as the structure doesn't change, stick to the plan. Don't test human nature; everyone wants to chase when they see an increase, but when it really rises, they often hesitate to chase. Therefore, the plan is very important; it can help us overcome our human nature, and we should just follow the plan unless the market deviates from the original analysis framework. We may need more time to observe or adjust our views.
