Ethereum, suggested to short at 1800 during the early morning. The overnight coin price peaked at around 1777. The daily K-line has broken the EMA30, and this is the first time it has returned to the EMA30 area to form short-term support. Although the coin price has rebounded above 1800, the overall trend is still in a downward structure. According to Ethereum's consistent characteristic of following the decline but not the rise, the possibility of continuing to break upward in the short term is low.

In the 4-hour chart, the overnight K-line stopped at the EMA15 area, and the trend indicator's upward expansion faced resistance. The MACD volume ended and began to decrease, with the DIF and DEA forming a death cross at high levels. After the Bollinger Bands opened up, the K-line fell to the middle track and stopped to rebound, showing clear short-term support. Similarly, the pressure at the top of the oscillation range is also clear, forming a short-term oscillation box in the 1800-1830 area. Therefore, in short-term operations, it is very simple: just intervene around the upper and lower edges of the box without breaking support and resistance.

On Friday morning, Ethereum is suggested to short at the upper edge of the box in the 1800-1830 area, while still paying attention to the 1680-1700 area below. For the short-term, treat it as a range.
