How is the futures K-line continuous? Shouldn't it be delivered?

For the convenience of analysis, the futures market software displays the futures contracts of the same month in different years. 100 1 The predecessor of the contract is: 090 1, 080 1, 070 1, 060 1 .................................................................

In addition, among the futures varieties, "Shanghai Copper Company, Shanghai Copper Company 3 and Shanghai Copper Company 4". What do these things mean?

They are not a specific futures contract, but are displayed by a number of related futures contracts, and cannot be traded directly (but the futures contracts displayed at that time can be traded).

Shanghai Copper Continuity: The futures contract that entered the delivery month through the link shows that the 0908 contract is currently displayed;

Shanghai Copper III: From the futures contract entering the delivery month to the futures contract counting down for three months. Currently, 09 1 1 contract is displayed;

Shanghai Copper Company 4: It is displayed by connecting the futures contract in the delivery month with the futures contract in the next four months. Currently, 09 12 contract is displayed.

Some varieties have only one "fuel continuity" and no "fuel continuity three or four". Why?

This may be related to the unusual delivery date of fuel oil: the last trading day of fuel oil is the last trading day before the contract delivery month 1 month, not the actual delivery month.
