3. Trend Direction Conclusion
The current PP price trend in China is volatile. Reason: The three first-order differences changed in the following directions compared to the previous day—flat, up, and down—respectively. No identical, unidirectional movement was observed, so the criteria for a clear uptrend or downtrend were not met. Consequently, the market is classified as ranging, with a short-term bearish bias.
4. Location and Spatial Reference
PP prices are in the fifth tier (high range) across 60-day, 3-month, and 1-year timeframes, leaving limited room for further upside.
