#美联储回购协议计划 Recently, liquidity has significantly tightened, and Bitcoin and Ethereum are both oscillating within narrow ranges. During the Christmas holiday, market enthusiasm has been low, with Bitcoin's volatility only a few thousand points, and Ethereum's fluctuations even smaller. Overall, the market remains sideways and repetitive. Breaking above or below key levels is not easy, so short-term trading should maintain a low-risk mindset; taking profits when available is advisable.

From the perspective of correlated assets, liquidity, and the four-year cycle, there is still potential for a breakout, but it requires a retest confirmation. However, intraday signals have not yet materialized, so the current approach is to continue trading within the existing range.

Technically, here are some reference levels:
- Bitcoin: Consider shorting around 88,000, add to short positions at 88,500-89,000, with targets at 86,500. If momentum is strong, try aiming for 85,500. If the retest does not break below 86,000, there is a chance for a quick long entry.
- Ethereum: Short around 2,970, add to short positions at 3,020-3,030, with targets at 2,900. If momentum is strong, look at 2,850-2,860. Similarly, if the retest does not break below 2,850, long positions can be considered.

This is the general idea; further judgment will depend on the retest performance.
