(-, -, +), indicating a deep pullback (bearish, with a corrective nature).
3. Trend Direction Conclusion
Oscillation (biased downwards), reason: The directions of change for the three averages compared to the previous day are not entirely consistent. Among them, the 5-day and 10-day averages have decreased compared to yesterday, while the 20-day average has increased, which fits the signal of a deep correction biased downwards within the oscillation range.
4. Positional Spatial Reference
The PTA 1-year cycle price is at a medium-to-high level with limited room for further increases; the 60-day cycle price is at a high level, with further upside potential constrained; and the 3-month cycle price is at a medium-to-low level, offering some support against further declines.
