Solana's recent market movement is interesting. In the past 24 hours, SOL's trading price surged to $144, a 2.9% increase, and at one point touched $147.08. The momentum looks good, but the $147 level acts like a hurdle—must break through, or this rally could come to a halt.

Comparing it with Bitcoin's performance makes it clearer. When BTC dropped 0.3%, SOL was still rising, indicating that the market still has expectations for Solana. Over the past week, it has gained a total of 4.1%, and over the past two weeks, a remarkable 15%. This slope is indeed impressive. The key question is whether this momentum can be sustained.

From the 4-hour chart, the issue is clear: the upper Bollinger Band is stuck around $146.5. TradingView charts show this level as a clear resistance zone. The True Strength Index (TSI) currently reads 24.54, with the signal line at 16.94. The indicator suggests that the momentum is still positive but not yet overbought—meaning there is room for further upward movement, provided this resistance can be broken.

What happens if it breaks through? The likely target is $148.2. But what if it can't hold here? Then be prepared for a pullback, possibly stabilizing at $140 or even lower at $134. The Bollinger Bands currently indicate increased market volatility, which makes this resistance level especially critical. Ultimately, Solana's next move depends on this battle.
