2. Signal Status Determination
Currently, this constitutes a clear bearish signal.
3. Trend Direction Conclusion
The trend is clearly downward, for the following reason: the three moving averages—D5, D10, and D20—have all changed in the same direction as the previous day, namely downward, thereby satisfying the criterion of the moving-average method for identifying a clear downtrend.
4. Positional Space Reference
PTA 60-day cycle price is at a medium-high level, and the 3-month and 1-year cycle prices are at high levels. The overall upside potential is limited, and there is a larger space for downward momentum to be released under high-level operations.
