First of all, the specific futures contract you trade is composed of contract code+delivery month. For example, you traded the contract C 1409 in June of 20438+00 this year, which means that if your margin is completely sufficient (that is, no matter how the market goes up or down, your funds can meet the margin requirements after deducting losses), you can hold it until 2065438+. Before the last trading day in August, if you don't close your position, you will be forced to close your position by the exchange (the closing price is closing your position at the current market price). Of course, if you are a corporate customer, you can issue or accept VAT invoices, or you can smoothly enter the delivery month (September 20 14) and enter the physical delivery stage after the last trading day (the tenth trading day in September 20 14).

Of course, the situation I described is basically impossible, and you can't stick to your post for that long. Because futures is a margin trading system, the market may change greatly for such a long time, and the profit is hard to say. If there is a loss, the amount of loss will be relatively large.
