The current price of sol is located in a concentrated area of negative gamma, and recent volatility has shown a general decline. There is a high probability of a pullback. We will verify whether the prediction is accurate in the next one or two days. The oscillation between 195 and 210 is expected to intensify. Once it goes down, there is no obvious positive gamma support. The volatility at the strike price of 150 is rising. I estimate that everyone should buy insurance around this price level. $SOL
