Is there any connection between the varieties of the same futures with different delivery periods, such as copper 1 104 and copper 1 105? How will the trend be different?
There must be something. According to the volume, a variety will have a main contract. For example, 1 104 is the main contract, then the price of 1 105 is generally higher than the main contract. Their trends are roughly the same, but they will not be exactly the same, because after all, only one of the two contracts is the main contract, and the other contract will definitely be different in terms of capital attention. The price will be different, but not too big.
