The main futures contract did not fall. During the conversion of the main contract, it will not rise, but will only fall. Long people want to buy positions at a lower point, and short people certainly want to close positions at a lower point. Now the main contract has become a second main contract, and there will be a big decline. Whether before or after. So many positions must be moved, and the first position to be moved must be long, because the unstable short position has been hung up.
