2. Signal Status Determination
Three differences are all negative compared to the previous day, which is a clear signal of decline.
3. Trend Direction Conclusion
Clearly downward trend. Reason: According to the mean difference method’s judgment criteria, when the directions of change in the three mean differences are completely consistent and negative, it meets the standard for a clear downward trend. From a fundamental perspective, ethanol market prices in multiple regions including Henan, Anhui, and Shandong have been relatively weak; factory quotes have slightly softened or declined, downstream demand remains weak, and transactions have been moderate. The combined effect of supply and demand is driving short-term price declines.
4. Positional Spatial Reference
Ethanol 60-day cycle price is at a low level, and the 3-month cycle price is also at a low level, indicating limited short-term downward space; the 1-year cycle price is at a medium level, providing some support for price declines.
