2. Signal Status Judgment
Clearly identify a downtrend signal
3. Trend Direction Conclusion
The price trend is clearly downward. Reason: The changes in the 5-day, 10-day, and 20-day moving average differences from the previous day are all negative, which is consistent with the rules for determining a clear downward trend using the moving average difference method.
4. Positional Space Reference
PTA prices for the 60-day and 3-month cycles are in the fourth tier (mid-to-high range), while the 1-year cycle is in the fifth tier (high range). Overall, prices remain relatively elevated, with limited room for further gains, and the current downtrend still has some room to unwind.
