Therefore, it is judged as an oscillation trend, showing characteristics of resistance to decline with a bias towards more oscillation.

1 year cycle price position: low, with limited downside space;
Price positioning for the 3-month cycle: Median, with relatively balanced upside and downside potential;
60-day cycle price position: at a medium-high level, with limited upside potential.
