The rebound of SOL in the afternoon after hitting 211 is due to the support of the middle Bollinger band on the 3-day line. Last Friday, a small loss of 2 points was used to attempt a long position, and if 224.25 breaks down, wait for 214-210 to buy the dip.
The current maximum pressure is around the middle Bollinger band on the daily line near 228.25, so the rebound around 227.50 quickly retraced. After breaking 228, it can be pursued; if it doesn't break, continue to gradually enter long positions below 218. It is not included in the daily short-term trading scope for now. SOL is also close to counterattacking.
