Solana's recent one-month trend can be summarized as "initial surge followed by decline." As of January 21, the price of SOL stands at $127.37, which is a 4.6% drop compared to 24 hours ago and approximately a 12% decline over the past week.

Looking back over the past four weeks, SOL's trajectory is indeed worth reviewing. In mid-January, boosted by expectations of ETF approval and network upgrades, SOL once surged to a high of $144, with market sentiment being quite optimistic. However, on the 19th, geopolitical tensions and tariff news disrupted this momentum, pushing the price down to around $124, marking a significant correction.

From a technical perspective, the $120-$130 range has formed a key support level, while $140 serves as a recent major resistance. In the short term, the market still leans towards sideways and weak patterns. Close attention should be paid to the progress of the Federal Reserve meeting and SOL's unlocking schedule, as these factors could trigger the next wave of price movements.

For trading strategies, high sell and low buy remain more stable options. Don't forget to set stop-loss points; the $120 level can serve as an important reference.
