Observing the 4-hour Candlestick Chart of SOL, we can identify a noteworthy market signal: a typical M-top pattern has already formed on the weekly level. This technical pattern is generally considered a potential bearish signal, which may indicate a shift in market direction in the short term.

At the same time, the MACD indicator also provides some interesting information. Although the histogram remains positive, we notice that it is gradually shortening. This phenomenon is usually interpreted as the bullish power gradually weakening, which may indicate that buying pressure is decreasing.

Based on this technical analysis, we have a cautious attitude towards the short-term trend of SOL. Currently, the $206-$210 range may be a sell opportunity worth following. However, investors should also closely monitor the $215 level, as a breakthrough at this level could change the short-term trend.

From a longer time frame, we believe that SOL may pull back to the level of 190 dollars. From a medium to long-term perspective, around 170 dollars may become an important support level.

It is important to emphasize that market trends are influenced by various factors, including but not limited to the global economic situation, changes in regulatory policies, and industry development. Investors should comprehensively consider these factors when making decisions and develop suitable investment strategies based on their own risk tolerance.
