From today's market conditions, the key focus for SOL is on the price level of 145.4. If the price successfully stabilizes above this level, a rebound trend on the 4-hour timeframe may initiate, with resistance levels above at 149, 152.4, and 155.7. However, if the rebound fails to reach 145.3, it indicates a weak rebound strength at the short-term 1-2 hour level, and the price will continue to test downwards. The lower levels of 143, 141, and 138 will become key support.
