First of all, we should pay attention to prevent the wrong direction. The direction of placing an order is also the direction of buying and selling. Because stock index futures have a short-selling mechanism, when you open a position, you can buy a warehouse receipt or sell a warehouse receipt. For example, investors expect the price to rise, but mistakenly put the buying warehouse receipt into the selling warehouse receipt when opening the position, and the system will accept and close the transaction, thus causing operational risks to investors. Therefore, investors, especially those who have not engaged in futures trading, should first pay attention to the direction of placing orders.
Secondly, we should guard against the mistake of order quantity. For example, "Shanghai and Shenzhen 300 Stock Index Futures Contract", the minimum order quantity is 1 lot, 1 lot = 1 lot; In the current stock spot trading, although the unit that clinches a deal also uses the concept of "hand" statistically, the concept of "share" is adopted in the actual order ("1 hand" equals 100 shares). Therefore, for stock investors, it is very cautious to engage in stock index futures trading.
Finally, it is necessary to indicate whether to open or close the position. Establish long positions, place orders for buying and opening positions, and place orders for closing long positions; To establish short positions, you should place an order to sell and open positions, and close short positions, you should place an order to buy and close positions. If the closing order is made into warehouse receipt, investors will have to pay the deposit of the opening contract, which increases the risk of fund management.
