Excuse me, what is this yellow line in the K line? Why did it open so much lower after crossing the yellow line? This is futures.
This yellow line represents the expiration of the contract, such as sugar 1505, which will happen at the time of delivery. After the yellow line, the main force has become 1506. I don't know if you can understand this. As can be seen from the volume, the volume near the yellow line is gradually decreasing, because everyone is closing positions.
