Quite simply, a deposit of 10% means that you only need to pay one tenth of the total transaction amount. For example, if you buy five lots of copper contracts, each lot is 5 tons, and each ton is 5,000 yuan, then the total transaction amount is125,000 yuan. Then, you only need to pay a deposit of 10%, which is 65438+. Nothing complicated. Futures trading is a bit strange to us, but it is not mysterious. good luck
