Under a custom cycle of 45 minutes, the trend of ETH and SOL implies a turning signal: ETH: Short term gains are accompanied by an increase in trading volume, but the position difference is negative, indicating that bears may be replenishing. If the closing price fails to break through the key pressure level of $1632, be alert to the risk of a pullback. The support range for the lower moving average is between $1593 and $1597, and if it rises, pay attention to strong resistance of $1660. SOL: During the rebound period, the position continues to decline, and the selling pressure gradually increases. In the short term, it may fall back to the test moving average support of $138.5. If it falls below, the next defensive support will be at $136, with strong pressure above $143. The data is for reference only and does not constitute investment advice!
