SOL's recent movement is quite interesting. From the 1-hour chart, it first rebounded from the low of 132.50 to 140.17, but was then blocked down again, now oscillating around 139.17. But if we talk about the real issue, it's still on the 4-hour cycle—signals are already very clear.

The Bollinger Bands are continuously narrowing, with the upper band turning downward, indicating that volatility is decreasing. Once it breaks downward, the lower band won't be able to hold. Looking at the MACD, the bullish momentum is clearly weakening, with the red bars shrinking, and the DIF and DEA lines getting closer, a death cross could appear at any moment.

Based on this judgment, consider shorting on rebounds. The 141-144 range is a good entry zone, with short-term targets at 135-128. If the trend worsens, it might test 125. But one thing to note—if the price effectively breaks above 145, stop-loss must be executed, don't hold through it, as the risk of trend reversal still exists.
