Closing positions can be divided into weekday positions and overnight positions.

In the past, more than half of the varieties in Pingjincang were free.

At present, only five or six positions such as copper, aluminum, zinc and corn are available.

There will always be a handling fee if you close your position overnight.

At present, the overall cost is still not high, such as the handling fee of more than 3 lines, one point is 10.

Corn is even lower, with a round trip of more than one yuan on the same day, and there is also 10 yuan at one point.
