If the current 30-minute $SOL does not continue to rise, then the lower edge of the top interval on the chart, 176.72, should be paid attention to. If it falls below and recovers quickly, this point cannot be broken again if it does not rise again. If it is broken again with volume, the certainty of this top interval will come out. The idea on the right side is to follow up on the broken interval, and stop loss at the recent high point (short) or the recent low point (long). Then wait and see whether the market will make you earn money, so there is a high probability of small losses and big profits, and it is safer to enter on the right side.
