ETH currently has a good shorting opportunity; consider positioning around 3290.

The key is whether 3238 can hold. As long as this line isn't broken, the bullish momentum remains strong, and the outlook continues to be bullish. The resistance levels above are sequentially: 3307, 3357, 3397.

Conversely, if it breaks below 3238, it indicates a correction in smaller timeframes. At this point, the support levels below become lifelines: 3200, 3155, 3117. These levels should all be monitored.

In summary, the focus is around the 3238 line—there's a ceiling above and a floor below, and the market always needs to choose a direction.
