Refund of futures margin: how much should the margin be refunded if there are many positions?
Profit =(6000-3000)* 10- commission first hand+profit =v(6000-5000)* 10- commission second hand = total profit. However, this is not the case. If the settlement price of domestic futures fluctuates on the previous trading day, the margin exceeding -+4-5% will be deducted.
