Overnight Lun copper plummeted, Shanghai copper held on to 52000 yuan per ton, the Shanghai-London ratio continued to be revised, imported copper was still actively exchanged, and some domestic copper, such as Shandong Yimeng and Shandong, which went to Shanghai, showed an urgent willingness to ship and exchange cash. The morning market is impatient to quote in the range of 220 × 200 yuan / ton, good copper will be reduced to 150 × 140 yuan / ton, and even a few small traders will quote 160 yuan / ton of good copper to attract the attention of the market. Imported copper is still the main supplier of the market, traders speculate and stock up at low prices, and the level of transactions is on the low side. Today is the Lantern Festival, and from next week, downstream and traders' transactions will be on the normal track, but the inventory of the major traders is not low, and the financial pressure is also greater. The market is faced with the game brought about by the contradiction between long and short, between supply and demand, and between capital and delivery.
