2. Signal Status Determination
Clearly rising (all three mean differences show a positive change compared to the previous day)
3. Trend Direction Conclusion
The price trend is clearly upward. Reason: According to the moving average difference method, the changes in the 5-day, 10-day, and 20-day moving averages over the previous day all show the same direction—positive—and fully meet the criteria for a clear upward trend. Meanwhile, factors such as the upward revision of CFR China PTA quotations on the international market and the reduction in output at some plants are also providing support for prices.
4. Positional Spatial Reference
60-day cycle price is at a high level, with limited upside potential;
Prices for 3-month and 1-year cycles are at mid-to-high levels, and there is still some upward momentum in the short term; however, in the high-price range, one should be wary of the risk of a pullback.
