How is futures settled?
The daily profit is calculated according to the settlement price.

In your example, if you open a position on the same day, you will lose money. You can deduct it directly from the deposit account. But after the settlement, your loss or profit cannot be transferred to the bank account through the silver period. You continue to participate in the trading at the opening price the next day, which is equivalent to the system closing the position at the settlement price every day and opening the position at the settlement price the next day. It has nothing to do with your profit or loss.

The calculation formula is as follows.

1, the profit and loss of the day can be calculated item by item.

The itemized settlement formula is: profit and loss of the day = profit and loss of liquidation+profit and loss of position.

(1) Ending profit and loss = average historical profit and loss+average current profit and loss.

Average historical warehouse profit and loss = ∑ [(selling closing price-settlement price on the last trading day) * selling volume]+∑ [(settlement price on the last trading day-buying closing price) * buying volume]

Average profit and loss of the day = ∑ [(selling closing price of the day-buying opening price of the day) * selling closing amount]+∑ [(selling opening price of the day-buying closing price of the day) * buying closing amount]

(2) Position profit and loss = historical position profit and loss+opening profit and loss on the same day

Historical position profit and loss = (settlement price of the day-settlement price of the previous day) * position.

Opening profit and loss of the day = ∑ [(selling opening price-settlement price of the day) * selling opening quantity]+∑ [(settlement price of the day-buying opening price) * buying opening quantity]

(3) The profit and loss of the day can be integrated into a general formula.

Profit and loss of the day = ∑ [(selling price-settlement price of the day) * sold quantity]+∑ [(settlement price of the day-settlement price of the day) *]+(settlement price of the previous trading day-settlement price of the day) * (selling position of the previous trading day-buying position of the previous trading day)

2. Calculation of margin balance

The balance of settlement reserve refers to the settlement reserve of the current day = settlement reserve of the previous trading day+deposit and withdrawal+trading deposit of the previous trading day-trading deposit of the current day+profit and loss handling fee, etc.

According to your example, closing profit and loss =0, opening profit and loss =273 1-2738=-7.
