December 30th ETH short-term bias is oscillating and weak, mainly aiming for high short positions on rebounds and low long positions on support; key boundaries: 2980 (break above turns bullish), 2890 (break below turns bearish).

1. Core Price Levels (12/30 13:30, current price ≈ 2940)

• Resistance: 2965 (50EMA), 2980 (100EMA), 3010 (daily structure), 3083 (200-day moving average)

• Support: 2920 (lower boundary of range), 2890 (strong support), 2850 (key platform), 2750 (previous low)

2. Technical Indicators (4h+1h)

• 4h: Price below EMA30/100, RSI≈42 (weak), MACD below zero line with death cross, decreasing histogram (weakening bearish momentum)

• 1h: Continuous bullish rebound candlesticks, MACD golden cross but insufficient volume, clear resistance above

• Conclusion: Short-term oscillation leaning bearish, rebound lacks strength, need to break 2980 to turn bullish, breaking below 2890 accelerates decline

3. Executable Strategies (Contracts/Short-term)
