On January 18th, ETH is currently around $3300. The daily chart shows a symmetrical triangle convergence, with narrow fluctuations on the 4-hour chart. The breakout window is approaching. The strategy is triggered by key level breakthroughs/breakdowns, with strict control over position size and stop-loss.

1. Core Price Levels (USD)

- Support: 3250 (strong support, if broken look at 3200-3215), 3200 (EMA/previous low resonance)
- Resistance: 3300 (key dividing line between bulls and bears), 3360-3380 (upper band/previous high, breakout target at 3400)
- Central Zone: 3280-3300 (core consolidation area)

2. Trading Strategies (by scenario)

1. Bullish Strategy (Conservative)
- Trigger: Volume increase and stabilization above 3300 (hourly close), with a retest confirmation
- Entry: 3300-3310, stop-loss at 3270 (below central zone), target 3360, breakout towards 3400
- Position: Spot ≤30%, futures ≤2x leverage, light position for trial

2. Bearish Strategy (Aggressive)
- Trigger: Volume decline and breakdown below 3250 (hourly close), weak rebound
- Entry: 3240-3250, stop-loss at 3280 (upper boundary of central zone), target 3200, breakdown target at 3150
- Position: futures ≤2x leverage, quick entry and exit, no overnight holding

3. Range-bound Strategy (Neutral)
- Range: 3250-3300, buy low and sell high within the range, small long positions near 3250, small short positions near 3300
- Stop-loss: 30 points each, target 50-80 points, take profit promptly, avoid holding positions during uncertainty

3. Risk and Risk Management Points

- Breakout risk: At the triangle convergence end, beware of false breakouts, no chasing without volume
- Stop-loss rule: Single loss ≤ 2% of total funds, strictly prohibit holding through losses
- Position management: Low liquidity on weekends, total position ≤50%, be cautious with heavy leverage on futures
- News focus: Monitor ETF fund flows, regulatory developments, prioritize reducing positions on negative news

4. Position Holding Recommendations

- Spot: Hold ≤30%, add on dips at 3250, reduce at 3360, implement rolling adjustments
- Futures: During consolidation, focus on short-term trades, avoid overnight positions to prevent gap risks

5. Core Mindset for Today

Range-bound and cautious. Slightly bullish above 3300, slightly bearish below 3250. Wait for clear signals; if none, stay on the sidelines. The breakout window is approaching. Be patient, wait for volume confirmation before increasing positions. Prioritize risk control.
