As of 11:50 on December 18 (UTC+8), SOL is approximately $127.8. The daily chart is dominated by a bearish trend, with weak rebounds during the 4-hour oversold condition. Overall, the market is oscillating weakly, linked to BTC, mainly shorting on rebounds and lightly trying long positions at low levels.

Core Price Levels and Key Multi-Period Support/Resistance

• Daily: Support at 123/121 (strong support); Resistance at 131/135-137 (strong resistance)

• 4-Hour: Support at 126/123; Resistance at 130-131/134.5

• 2-Hour: Support at 127; Resistance at 129-130. Bollinger Bands are converging, increasing the likelihood of range-bound oscillation.

Multi-Period Technical Analysis

• Daily: MACD death cross, KDJ downward divergence, 50/200-day moving average death cross, continuation of the bearish trend; price below short-term moving averages, no clear sign of bottoming, rebound is weak.

• 4-Hour: RSI around 30 (oversold), MACD bottom divergence with decreasing volume, indicating weak rebound potential; EMA15 at 131 forms strong resistance, lower Bollinger Band at 126 provides immediate support.

• 2-Hour: Volume shrinking, price oscillating below the middle band, awaiting breakout direction; focus on whether it can break above 129-130, which will determine short-term rebound strength.

Technical Signals and Structural Points

1. Trend: Daily is in a downtrend channel, 4-hour oversold but no clear reversal signal, 2-hour waiting for breakout.

2. Volume: Trading volume in the past 24 hours has shrunk compared to previous days, rebound momentum is insufficient, sustained movement requires volume breakout.

3. Divergence: 4-hour MACD bottom divergence suggests a possible rebound, but at a small scale; confirmation requires price to break above 131.

4. Linkage: Strong linkage with BTC; the breakout direction in the 85,000-87,500 range will determine SOL's trading rhythm.

Actionable Trading Strategies (with stop-loss)

1. Rebound Short: Short at 130-131, stop-loss at 133, target 127-126; if broken, look for 123-121.

2. Pullback Long: Light long positions at 123-124, stop-loss at 121, target 127-129; if broken, target 131.

3. Breakout Strategy: Volume breakout above 131, retest at 129 for long entry, stop-loss at 127; volume breakout below 123, rebound at 125 for short entry, stop-loss at 127.

Risk Management Points

• Position size ≤30%, always include stop-loss to avoid extreme volatility.

• Prioritize executing rebound shorts; low-level longs should be light and quick in/out.

• Closely monitor the validity of the 121 support; a breakdown will accelerate the decline toward 118-115.
