1, the charges vary from family to family. Transaction costs include spread (spot copper spread is 0.65438+ 0% of the settlement price of the previous trading day), handling fee (six thousandths) and demurrage fee (one thousandth). Spot copper's handling fee shall not exceed 6/10000 of the transaction amount.

2. For example, if an investor buys a first-hand spot copper at a price of 42,000 yuan/ton (the first-hand spot copper is 5 tons), the handling fee should be: 42,000×/kloc-0 /× 5× 0.06% =126 yuan; If the customer closes the position at the price of 43,500 yuan/ton, the handling fee that the customer should charge when closing the position is: 43,500×/kloc-0 /× 5× 0.06% =130.5 yuan, and the handling fee that the customer should pay in this transaction is:126+130.
