We need to take a look at the situation of $ETH now in the four-hour and one-hour timeframes! According to normal logic, the four-hour chart requires a refueling. We could have entered a long position based on the one-hour golden cross, but don't rush; everyone should pay attention to whether this position can refuel! The one-hour chart has already risen, and there have been many green candles, so there isn't another one-hour golden cross at the moment. Therefore, we must wait to go long; when the one-hour chart pulls back and forms a golden cross again, we can confirm and take the four-hour refueling. This is the approach for going long. But how do we go short? It's simple: when the one-hour chart turns to form a death cross, we confirm entry from the 30-minute death cross! This will trigger a leak in the four-hour chart! So whether we go long or short, there is logic to follow, and we can know in advance what position to wait for what opportunity! This is trading!
