SOL's recent trend shows clear bearish signals on the technical front. After retreating from the high of 148.71, the price faced resistance at 143.23, and the upper band of the Bollinger Bands is also warning of limited upside potential.

Looking at the 4-hour indicator combination, the signals are quite consistent:

**RSI** quickly dropped from 37.98 to around 27.82, reflecting a significant decline in momentum.

**KDJ** shows the J value falling below 20, indicating short-term oversold conditions while also suggesting that downward inertia remains.

**MACD**'s green histogram continues to expand, with DIF and DEA at -2.34 and -1.26 respectively. The bearish crossover below zero is still widening, indicating that the downward momentum has not shown signs of weakening.

From an operational perspective, several key price levels to watch are:

**138-140 zone** can be considered a critical resistance area for a rebound. If the price rebounds to this region, its resistance performance will be crucial.

**143.23** is a recent clear upper resistance. The extent to which this level is broken will directly influence subsequent movements.

**130 and 125** are important technical support levels on the downside. Among them, 125 has appeared multiple times in recent technical analysis frameworks.

Overall, SOL's current technical situation is in a typical downward testing phase. The specific trend will depend on how the price performs at key levels and the accompanying volume.
