$ETH trend analysis:
Currently, the market seems to be struggling to decline, and the exchange rate has also stopped falling. With the Spring Festival approaching, there is a high probability of a rebound. $ETH shows a trend of forming a double bottom; if there is a recent increase in volume that breaks through the resistance levels of 2040 and 2150, it is expected to initiate a rebound testing 2400 and 2600.

Operational thoughts:
1. Wait for a breakout signal to go long in the short term.
2. Wait for a rebound to the resistance level to go short at high positions.

Execution plan:
- Short-term long: enter long at the breakout of 2150, target 2400, 2600, stop loss at 1950.
- High position short: set up short positions near 2600, stop loss at 2700.
