II. Signal State Determination
The current three deviations have changed direction from the previous day as (unchanged, negative, negative), which aligns with the approximate characteristics of a volatile market (positive, negative, negative), indicating a weak rebound (bearish) signal.
3. Trend Direction Conclusion
The current trend in phthalic anhydride prices in China is oscillating with a bearish bias, for the following reasons: the changes in the three moving averages compared to the previous day are not entirely consistent, which does not meet the criteria for a clear upward or downward trend. Therefore, the overall trend is oscillating. At the same time, the 10-day and 20-day moving averages are both declining, indicating that the short- to medium-term upward momentum is gradually weakening, and the probability of a bearish trend is relatively high.
4. Spatial Reference
Phthalic anhydride 60-day, 3-month, and 1-year cycle prices are all in the 5th tier (high), with limited room for increase, and a higher risk of a pullback from the high levels.
