The London copper we are talking about refers to 3 London coppers. It represents the average price of the next three months, which can be understood as the middle month. Then it has no expiration month, so its graph is always continuous. Therefore, you will only see 3-level copper, but not 4, 5, or 6-level copper.

For example, what we usually talk about is Shanghai Copper 0709, which is the specific copper futures for September 2007, and the contract must be delivered when it expires.

Shanghai Copper Continuous refers to the contract of the latest month; Continuous Three refers to the contract of the third month from near to far, and Continuous Four is the same as this type.

You can see that the Shanghai Copper Continuous you see today is exactly the same as Shanghai Copper 0707. And Shanghai Lian San is the same as Shanghai Copper 0710.

When you place an order, you must place your order within the specific month of Shanghai Copper.
