$DOG is relatively strong in terms of trend. It has retreated at the hourly level, which happens to be the neckline support level at the hourly level, which is also the middle position of the red frame area. After the retreat, there is a rebound. The upper edge of the red frame is still a strong pressure. The operation strategy remains unchanged. Either wait for the retreat after the breakthrough before buying, or retreat to the lower edge of the red frame area, that is, buy in batches in the 2400-2200-2000-2000 area.
