By analyzing the three important swing trading phases in SOL's price movement over the past six months, we can identify key buying opportunities for short-term trading.

First swing trading pullback analysis:
From 273 down to 95.19, a decrease of 177.81 points. According to the volatility ratio, 0.382 is at 67.92 points, 0.5 is at 88.91 points, and 0.618 is at 109.89 points.

Swing trading upward analysis:
It rebounded from 95.19 to 187.67, up 92.48 points. Combined with the previous decline, three potential resistance zones are calculated: 163.19 (plus 68 points), 184.19 (plus 89 points) and 205.19 (plus 110 points). The actual high of 187.67 indicates that the rally has reached the 0.5 coefficient level.

Swing trading pullback analysis:
Based on a gain of 92.48 points, the 0.382 pullback is 35.33 points, the 0.5 pullback is 46.24 points, and the 0.618 pullback is 57.15 points. This means that the key support levels are at 152.35, 141.43 and 130.52, respectively.

Recent market verification shows that effective support has been formed near 141.5, and there has been a rebound after hitting it many times in two weeks, which is in line with the characteristics of 0.5 callback coefficient. This explains why 141.5 is an ideal low-suction spot in the near future.

Looking ahead to the market, 141.5 acts as a key support level. If it is effectively broken, the next buying opportunity will appear around 130.5. However, if the price retests 141.5 and can hold, it can still be seen as a good opportunity to build positions at a low level.
