It must ensure that the supply in the market is equal to the order quantity. Because the goods exist in the warehouse from the beginning, we can adopt the methods of early delivery and due delivery, and the delivery method is flexible.

Two: the lever is different. The margin of futures is 5% to 10%, which is risky. The margin of spot electronic trading is 20%, which is moderate.

Three: there are different restrictions on ups and downs. The futures price limit is 200%, and the risk is huge. The price limit of spot electronic trading is 6%, which is less risky.
