Because of the influence of two futures systems, the two futures systems are 1, the settlement price system 2 and the debt-free settlement system on the same day. In order to prevent funds from manipulating the closing price and disturbing the market, the exchange abandons the closing price and adopts the settlement price for daily settlement. Futures settlement price is the weighted average price of all trading orders on that day. Why does the profit show a floating loss? Let me give you an example. If you use 9 yuan to make multiple orders, the closing price is 10 yuan, and the settlement price is 8 yuan. Before settlement, your order shows profit 1 yuan, and after settlement, it shows loss 1 yuan, but in fact, the total amount of equity has not changed. The above is called floating profit and loss. Of course, your actual profit and loss is the same as this.
