The "Administrative Measures for Futures Companies" stipulates that if a trading order is issued in writing, the customer should fill in a written trading order form; if a trading order is issued by telephone, the futures company should record it simultaneously; by computer or Internet If a trading order is issued through entrustment, the futures company shall save the trading order in an appropriate manner. The ordering method of stock index futures trading is quite different from that of stock trading. Investors should avoid the risk of placing wrong orders: First, pay attention to prevent placing orders in the wrong direction. The order direction is the buying and selling direction. Since stock index futures have a short-selling mechanism, when opening a position, the transaction can be completed regardless of whether you place a "buy to open" order or a "sell to open" order. For example, if an investor expects the price to rise, but mistakenly places a buy opening order instead of a sell opening order when opening a position, the trading system will accept it and may complete the transaction, which may cause losses to the investor. Therefore, investors, especially those who have never engaged in futures trading, must first pay attention to the direction of placing orders. Secondly, we must guard against errors in the order quantity. In the Shanghai and Shenzhen 300 stock index futures trading, the minimum order quantity is 1 lot; in the current stock spot trading, although "lot" is also used as the counting unit when counting trading volumes (1 lot = 100 shares), but When actually placing an order, "share" is used as the counting unit. Therefore, stock investors should pay attention to the differences when participating in stock index futures trading. Finally, it is also necessary to indicate whether it is "opening" or "closing". To establish a long position, a buy opening order should be issued, and to close a long position, a sell closing order should be issued; to establish a short position, a sell opening order should be issued, and to close a short position, a buy closing order should be issued. If a closing order is placed instead of an opening order, the opening contract will occupy the trading margin, and will also increase the risk of investors' capital management.
