2. Signal Status Determination
The current deviation change combination is (－, －, ＋), which belongs to a mild correction (biased bearish, corrective nature) signal.
3. Trend Direction Conclusion
The short-term trend is choppy. Reason: The directions of the three differences compared to the previous day are not entirely consistent, which does not meet the criteria for a clear upward or downward trend. This is considered a volatile market situation and is currently in a mild corrective phase with a slightly bearish bias.
4. Positional Spatial Reference
Styrene prices over the 60-day, 3-month, and 1-year timeframes all remain in the fifth tier (high range, within the top 20% of the cycle), suggesting limited upside potential. During the mild correction phase, caution is advised regarding short-term downside risks.
