In short-term trading, there are actually two strategies available every day. One is to buy on a pullback, and the other is to chase the price at the current level. The logic for chasing the price at the current level is to follow the trend after breaking through key resistance points, without significant pressure from higher-level indicators. This approach is trend-following. Buying on a pullback is a conservative offensive strategy, waiting for opportunities within the range of the 1-3 nearest support points to the market price. Both methods must be used simultaneously in a strong upward trend; if you only stick to buying on pullbacks, you will miss out on many short-term opportunities, as the price may not even pull back to 0.382, while your orders are set at 0.5-0.618. Therefore, in the first three days of this week, it would be very difficult for you to capture a significant portion of the market, and you would at least miss out on half.
