I don't know if the outer disk and the inner disk mentioned by the landlord are the outer disk and the inner disk displayed by market software. If that's what you mean, then your understanding is wrong. The outer disk and the inner disk in the market represent the buyer and the seller respectively (the quantity determines which side is stronger and the direction may be taken, of course, this is not an absolute reference. What we usually say is that domestic futures prices will follow international futures prices. For example, domestic copper will follow the price of Lenton, and Lenton will change according to the level of the US dollar index. Just look at the main contracts of all futures, and you will know that the month with the largest position is the main contract. I have been making rebar recently, but I am still bearish in the short term. If it is a long time (the trend of next year), I will still read more, but I will definitely go down.
