How to calculate the settlement price and weighted average price of the monthly trading reference price of listed varieties (I am concerned about copper) in Shanghai Futures Exchange?
That is, for example, A sells at the price of A, B sells at the price of B, C sells at the price of C, D sells at the price of D, and so on. Weighting is to calculate the price according to the ratio of (A * A+B * B+C * D)/(A+B+C+D), that is, weighted average. The final settlement price of copper seems to be the weighted average of the last two hours. You can ask questions in the QQ group at 329028904. If you are interested in futures, read more.
