In principle, the trading of stock index futures is the same as that of securities, and centralized computer bidding is conducted according to the principle of price priority and time priority. Trading orders, like securities, have three kinds of orders: market order, limit orders order and cancellation order. Unlike securities, stock index futures are futures contracts, and the direction of buying and selling is very important, which is also a common mistake made by many stock investors when they do futures trading for the first time. Futures have two positions: long position and short position, which can be opened and closed in trading. Closing positions can also be divided into closing positions and over positions.

In the transaction, we should also pay attention to the terms of the contract. Generally speaking, there are four kinds of stock index futures contracts within half a year, namely, the spot month contract, the next month contract and the last two quarters contract. With the monthly delivery, the contract will be rolled forward once. For example, in September, there are four contracts: September,1October,1February and March of the following year, and the1October contract needs to be delivered at the end of1October.

Settlement refers to the business activities of calculating and distributing the trading margin, profit and loss, handling fees and other related funds of members and investors according to the trading results and relevant provisions of CICC.

Close position or delivery

Closing a position refers to the behavior of investors to end a transaction by buying or selling contracts of the same variety and quantity but in the opposite direction. Delivery refers to the behavior of investors in the form of cash settlement when the contract expires. The delivery of stock index futures is also different from stocks. Ordinary stock investors are used to spot trading, but it is easy to ignore that stock index futures contracts need to be settled in cash at the contract delivery price of the day, so they need to hold non-spot monthly contracts to hold positions.
