3. Drivers and risk control points

1. Drivers

- Technical: 4h/daily oscillation, no clear directional signal, leaning towards consolidation.

- Sentiment: Market trading is light, year-end fund repatriation, volatility limited.

2. Risk control suggestions

- Futures: Light positions, strict stop loss (longs 2880, shorts 3040), avoid chasing highs and selling lows.

- Spot: Dip to 2900-2930 for phased accumulation, reduce positions in 3030-3060 range.

4. Key observation signals

- Volume stabilizing above 3035 → bullish reinforcement; volume breaking below 2920 → increased bearish risk.
