If you buy gold, according to the current price of 20% of the day, there is a warehouse interest of 4 cents per ounce every day. No matter how long it takes to pick up the goods, as long as you pay the warehouse interest, 80% of the money, plus the processing fee of 8- 12 yuan/gram.

I really don't know the settlement price. I don't think there should be a settlement rule.
