The trend of SOL is consistent with the idea discussed in the video on the 24th, with a rebound at the position of 12HMA30. This rebound was significantly suppressed within the range of 196.7~21.4. From the perspective of the midline, it is relatively safe to retrace to the range of 178.3~172.4 in the future. Short term orders should be focused on 1H and below levels, mainly with fast in and fast out. The holding time should not be too long, and it is best to control it within 4 hours. SOL
