In the structure of the sky chart, the trend line has fallen below, the 123 rule has reached 1, and there are still 2 and 3 left. 2 means that it cannot rebound from the previous high, and 3 means that it fell below the key level (spot price 24800)

On the second rebound, pay attention to the upper positions that need to be monitored. These three positions are almost exactly 27450 (0.382), 28500 (0.5), and 29500 (0.618). These signals can participate in long-term short selling.

Today's sharp drop just fell to the support level near 25,000, which is the high point of the first rise and the starting point of the third rise.
