1. Long-short dividing line: 149.9 (4-hour level)

Core role:

- Maintain stability and be bullish: If the 4-hour K-line closing price does not fall below 149.9, the bullish trend continues, target pressure levels at 153.4→157.2→159.4.

- Break below is bearish: If this level is broken, a pullback at 4-hour level starts, with support levels at 147.5→144.8→141.2.

2. Long-short directional point analysis

Upward pressure level

1. Short-term resistance: 153.4 (recent high point, breaking it opens up mid-term space)

2. Mid-term resistance: 157.2 (historically dense transaction area, needs volume support)

3. Long-term resistance: 159.4 (round number + previous high, psychological resistance is strong)

Downward support level

1. First support: 147.5 (short-term support at 4-hour level, if lost, watch 144.8)

2. Second support: 144.8 (corresponding to previous oscillation low, mid-term trend reference)

3. Strong support: 141.2 (pullback limit, bearish strength may weaken)

3. Time-based operation suggestions

Bullish scenario (stabilize at 149.9)

- Aggressive strategy: After stabilizing at 4-hour level, enter light long positions at 149.9-150.5, stop loss at 149.0, targets at 153.4, 157.2 (add positions if breaking 153.4).

- Conservative strategy: After breaking 153.4, confirm support on pullback, then follow up with long positions, avoiding chasing highs.

Bearish scenario (break below 149.9)

- Aggressive strategy: Short directly after breaking, enter at 149.5-149.0, stop loss at 150.5, targets at 147.5, 144.8 (can chase shorts if breaking 147.5).

- Conservative strategy: Short after rebounding to 149.9, target as above, take profit around 144.8 and wait.

4. Risk warning

1. Cycle linkage: The trend of SOL is easily influenced by Bitcoin (BTC) and ETH, so mainstream coin movements should be monitored simultaneously.

2. Volume signal: Upward needs to break pressure level with increased volume, while downward should be cautious of volume shrinking rebounds (false breakdown).

3. Position control: Single trade position ≤3%, stop loss at 4-hour level can be slightly relaxed (e.g., 5-8 points).

Summary: 149.9 is the 'switch' of the 4-hour trend; if stabilized, watch for pressure levels to rise stepwise, if broken, explore downward along support levels. Adjust flexibly according to volume-price relationship and strictly enforce stop-loss discipline.$SOL #SOL走势
