**SOL short-term trend forecast (24-72 hours)** SOL currently fluctuates in the range of $142-$148, forming a convergence triangle at the 4-hour level. The key support is at $138 (Fibonacci 0.618 retracement). If it falls below or tests $132, the upper pressure is at $155 (the previous high-density area). A breakthrough requires heavy volume. RSI is neutral to weak (48), MACD lacks momentum, and may maintain range consolidation in the short term. On-chain activity and ETF capital flows have not yet provided directional drivers, and volatility is expected to narrow. *Note: Market risks and macro events (such as Fed comments) may disrupt this structure, please evaluate your own exposure. *
