Ethereum's volatility has been quite intense. During the day session, it dipped to around 2020, and in the evening, it spiked up to 2199, rebounding nearly 200 points.

Fortunately, it did not break through the 2200 level. Before any effective breakthrough, the strategy remains unchanged. Subsequently, it's likely to pull back and test the lower support of the range.

Short around 2180, stop loss at 2210, target 2110#ETH below.
