Analysis of the reasons for tonight's sharp drop.

1 Capital is seeking refuge ahead of tomorrow's major non-farm payroll report. This is critical data, the first important data released since the U.S. government shutdown.

2 The surge in silver has given many funds a reason to withdraw and chase after it.

3 The Christmas market, similar to the domestic Spring Festival. Entertainment is the focus, investment is weak.

Waiting for the data release, it seems a strong push is needed.
