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 four hours of trading time every day, which completely misses the time in Europe and America where the price fluctuates the most, resulting in a huge waste of trading opportunities.
