I. Data Description
The latest available public data for ammonium sulfate in China is up to September 19, 2026. It is recommended to refer to real-time data.
II. Table of Finite Differences
| Average Difference Indicator | (2026.09.19) | (2026.09.18) | Direction of Change |
|---|---|---|---|
| 5-Day Average Difference (D5) | 12.67 | 20.00 | - |
| 10-Day Average Difference (D10) | 16.00 | 15.00 | + |
| 20-Day Average Difference (D20) | 35.50 | 35.33 | + |
Three, Signal Status Determination
The current mean difference change combination is (－,＋,＋), which belongs to a strong consolidation (bullish) signal.
IV. Conclusion on Trend Direction
The current price trend is oscillating (with a bullish bias). Reason: The changes in the three differences from the previous day are not completely consistent, which does not meet the criteria for a clear upward or downward trend, and the overall situation is within an oscillating range. The 10-day and 20-day differences have both rebounded from the previous day. Additionally, the recent continuous increases in the factory prices of major domestic producers have provided strong support to the spot market fundamentals, showing characteristics of a strong consolidation.
V. Positional Space Reference
Ammonium sulfate 60-day cycle price is at a high level, 3-month cycle price is at a medium-low level, and 1-year cycle price is at a medium-low level. In the short term, there is limited room for further increases, but there is still potential for upward movement in the medium to long term.
