The analysis of Solana (SOLUSD) on the 1-hour timeframe indicates the completion of a C-wave to the upside, which has technically fulfilled its initial targets. The internal structure of this C-wave, particularly the fifth sub-wave, is described as potentially forming a diagonal pattern, implying that while a major uptrend might be concluding, one more local high remains plausible. Key resistance is identified between $148.50 and $154.88. The presenter specifies $148.50 as the lower bound of the next resistance zone for a potential additional high. Current support for the ongoing correction is situated between $139.84 (61.80% Fibonacci retracement) and $143.05 (38.20% Fibonacci retracement). A break below $139.84 would serve as an initial indication of a local top. A more significant confirmation of a top would occur with a decisive break below the $132.70 swing low, which formed on January 8th. The absence of a clear five-wave impulsive decline below existing support levels supports the continued possibility for an upward movement, although any further upside beyond the specified resistance is considered speculative given the advanced stage of the rally.
