Recently, Chinese DOP manufacturers have continuously raised their quotes. The high prices of upstream isooctanol and phthalic anhydride have provided strong cost support for DOP. However, the current DOP price is already at a high level within the last year's cycle. Short-term price momentum indicators show insufficient upward energy, and medium- to long-term momentum indicators have been declining continuously. Overall, it is in a weak rebound phase with limited upside potential. Downstream buyers need to be cautious of the risk of a pullback from the high levels.

II. Signal State Determination
The current signal is a weak rebound (bearish).
III. Conclusions on Trend Directions
The current DOP price trend is oscillating (with a bearish bias), as the changes in the three mean differences from the previous day are not entirely consistent. The short-term 5-day mean difference is unchanged, while the medium and long-term 10-day and 20-day mean differences have both declined compared to yesterday. This aligns with the characteristics of a weak rebound in an oscillating range, indicating insufficient upward momentum in the price.
4. Location and Spatial Reference
The current DOP 60-day, 3-month, and 1-year cycle prices are all in the 5th tier (high range), with limited room for increase, and there is a possibility of a high-level correction.
