1, spot copper's minimum price change unit is 1 yuan/ton, while futures copper is 10 yuan/ton, so spot copper's quotation is more accurate; 2. Futures copper has a daily maximum fluctuation limit, that is, the price limit, and spot copper does not exist; 3. Futures copper can no longer be held after the expiration of the month and must be delivered, which is not the case in spot copper; The biggest difference between them is the trading time. Spot copper can realize all-day uninterrupted trading, while futures copper only has a few hours of fixed trading time every day, completely missing the European and American time with the biggest price fluctuation, resulting in a huge waste of trading opportunities; From the above comparison, we can see that spot copper has obvious advantages in trading mechanism. So spot copper needs to do something.
