#美联储回购协议计划 December 28th Ethereum Technical Overview: The 2930-2990 USD range is repeatedly tugged back and forth, with no clear direction. Short-term is slightly weak, suitable for high-odds range trading strategies, but position sizing must be well-controlled. Total exposure should not exceed 30%, and during low liquidity weekends, be especially cautious of sudden spikes and false breakouts.

**1. Specific Support and Resistance Levels**

Remember these key support points below: 2930 is a strong support on the 4-hour chart, tested multiple times; 2900 is a psychological round number; 2880 is the stop-loss line; 2850 is a deeper support.

On the upside, resistance is concentrated around 2980-2990, where the 20-period moving average is also located, and this is the recent rebound high; 3000 is a psychological milestone with significant mental impact; further up, 3030 has recently formed a strong resistance.

**2. What Do the Charts and Indicators Say**

The 4-hour chart shows a classic bearish descending triangle—upper boundary at 2980-2990, with clear resistance. A breakdown below this level is quite possible. From the momentum perspective, ADX is below 20, indicating no clear trend; -DI is stronger than +DI, suggesting a slight bearish bias.

The daily chart is even more evident: price is below the 20-day moving average, under pressure, with a continued correction from high levels. MACD's positive histogram is shrinking, indicating weakening buying momentum; RSI is neutral without extreme divergence signals; Bollinger Bands are narrowing, with the middle band exerting clear resistance on the price.

Weekend liquidity is a concern; trading volume is low. If a breakout occurs, it must be confirmed by volume; otherwise, it’s likely a false move.

**3. How to Operate in Practice**

Prioritize short positions (better odds): buy small short positions on rebounds between 2970-2985, with a stop-loss at 2995. If volume breaks above the 20-day moving average, consider exiting. First target is 2930, reduce positions gradually; second target is 2900; if it falls further, watch 2880.

For longs, don’t rush. Wait until it stabilizes in the 2930-2940 range, then look for a 15-minute bullish candle to enter lightly. Place stop-loss at 2920; if volume drops below and price breaks down, abandon the trade. First target is 2970; if it breaks 2985, look at 2980; further break above targets 3000.

If a breakout occurs, how to follow? A break above 3000 with volume can be chased long, targeting 3030, with a stop-loss back at 2985 for protection. A breakdown below 2920 also requires volume confirmation; chase short to 2880, with a stop-loss at 2935.

**4. Risk Management Rules**

Single position size should not exceed 10% of the account; total exposure kept within 30%. Avoid leverage or use very low leverage as the baseline. During weekend nights from 22:00 to 04:00, liquidity is especially poor—avoid opening new positions, and set stop-loss orders on existing ones in advance.

Breakout signals must be strictly confirmed: volume + two consecutive 4-hour candles confirming the move. Avoid chasing after rapid gains or cutting losses impulsively. Keep an eye on the Federal Reserve’s liquidity policies, as changes may impact the overall risk appetite.

In summary, Ethereum remains in a stalemate this week, mainly focusing on high-odds swing trades, with strict risk control being the most critical.
