Solana (SOL) is exhibiting a constructive technical setup on the 4-hour chart, indicating a potential reversal. The cryptocurrency has formed a bearish Bat harmonic pattern, with key support identified at $119.24 following a decline from $140.11. Currently, SOL has rebounded to $123.52, with the 100-hour moving average at $128.00 being a critical level to watch. A sustained move above the 100-hour MA could see SOL targeting the $137.47 to $140.11 range. However, a close below the $119 support level would pose a challenge to the bullish outlook.
