Unlike stocks, each index futures contract has an expiration date on which the contract will stop being traded and converted into cash. At the same time, on that date, all open positions of mature contract will be closed at the end of the due date and any profit/loss will be credited into their account in the next working day. However, when the contract expires, the final settlement price (calculated based on the price of the underlying asset at the expiration date) will be used to calculate the end-of-maturity profit/loss (instead of using settlement price at the end of the day). This makes the underlying asset's price movement affect the price movement of the futures contract.

The maturity date of the VN30 Index futures contracts is set on the third Thursday in the month of maturity. Four futures contracts are available for trading at any time, with the respectively due dates set for the current month, next month, and the last month of the latest two quarters.

For example, Customer Nguyen Van A has a buying position for one VN30F1903 contract, which is due on March 21, 2019. On this day, he can continue to hold his buying position. If he does not close the position, the contract is deemed to be closed at the end of March 21, 2019. And, he will no longer hold the position of VN30F1903 contracts from March 22, 2019.

On the maturity date of the contract, if you do not close the position, your contract will automatically be settled based on the closing price of the underlying VN30-Index.

For example, Contract VN30F1806 is due on June 21, 2018. You place an order to buy this contract at 957.

• Closing price of Contract VN30F1806 is 954
• VN30-Index closes the ATC session at 955.75 on June 21, 2018.

If you place a selling order at the ATC price, your contract will be settled profit/loss at 954

If you do not close the position, the contract will be settled profit/loss according to the VN30-Index at 955.75.
