It is already the 27th, and there are only a few days left in August. Time flies. At the eth daily level, we can clearly see the closing, resulting in a narrow range of fluctuations. Today, we will focus on the eth daily level middle rail support position near 2620. As long as it does not break, it will fluctuate between the middle rail and the upper rail. However, if it breaks, we must pay attention to the 2500 daily level lower rail support position. We can always pay attention to how it runs to prevent sudden news.
