On the 4-hour level, SOL rebounded after touching the lower band, but don't rush to conclude that the market has reversed.

From the Bollinger Bands, it can be seen that there is strong resistance at the middle band near 138, which has not been broken, indicating insufficient rebound momentum in the short term, and it is highly likely to test the previous low of 125.8 again.

If this level holds, there may be a short-term technical rebound opportunity; once it is lost, pay attention to the secondary support levels below at 123.5, 120, etc.
