Ask me if my guess is correct: for example, after the delivery of soybean 0905, soybean 1005 is a new listing contract, so how long will soybean 1005 cease to be a new listing contract?

This is not right.

Dalian soybean futures contracts are divided into odd years and even years. After the delivery of the 0905 contract, the 1 105 contract will be displayed on the K line of the 0905 contract, but the 1 105 contract has been listed and traded for half a year, so in 2009 it was 1 1.

In fact,101contract was listed and traded after the delivery of contract 0905, and11contract was listed and traded after the delivery of contract 0907 in July.

The 1005 contract was listed and traded in June 2008.

About the settlement price, it is the weighted average price of the whole day.
