December 30th 14:10, ETH current price ≈ 2945, short-term oscillation is biased bearish, mainly aiming for rebounds to sell high and support low to buy; key dividing lines: 2990 (turn bullish), 2920 (turn bearish).

1. Core Price Levels

• Resistance: 2960 (4h EMA30), 2990 (upper boundary of range / 100EMA), 3020 (previous high), 3050 (integer threshold)

• Support: 2940 (lower boundary of range), 2920 (strong support), 2880 (100-week EMA), 2850 (previous platform)

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: Candlestick rebound weak, MACD golden cross but insufficient volume, clear resistance above

• Conclusion: Short-term oscillation is biased bearish, rebound is weak, need to break 2990 to turn bullish, falling below 2920 accelerates downward movement

3. Executable Strategies (Contracts/Short-term)

1. Rebound to sell high (main strategy)

• Entry: Short positions in batches at 2960-2990, initial position at 2960, add at 2990

• Stop loss: 3010 (2990 + 20 points)

• Targets: 2940 (first), 2920 (second), 2880 (third, hold if broken)

2. Support low buy (auxiliary strategy)

• Entry: Long positions stabilized at 2920-2930 (wait for 1h bullish close / long lower shadow confirmation)

• Stop loss: 2900 (2920 - 20 points)

• Targets: 2945 (first), 2960 (second, take profit upon resistance)

3. Breakout chase orders (after confirmation)

• Long: If 2990 stabilizes (1h close), chase long, stop loss 2970, targets 3020-3050

• Short: If 2920 breaks down (1h close), chase short, stop loss 2940, targets 2880-2850

4. Risk Control and Execution Points

• Position size: single strategy ≤20%, total position ≤50%; enter in batches, avoid heavy bets on breakouts

• Take profit: reduce positions at each target, first target reduce by 50%, second by 30%, remaining based on breakout levels

• Trigger: after breaking key levels, wait for 1h close confirmation before acting to avoid false breakouts
