Ethereum (ETH) is encountering a significant $171 million order wall as it tests key volume levels ahead of the Consumer Price Index (CPI) data release. The 45-minute cycle signal indicates ETH is crossing below the EMA89, with open interest declining and momentum converging. Major players have placed large orders, including two exceeding $19 million each, at the current price level. The upcoming CPI data, expected at 8:30 PM, could influence market direction, with the order wall serving as a short-term liquidity target.
