For example, an investor opened his position in 65438+February 15, and bought 10 futures in 65438+ 10, and the transaction price was 1400 points. At this time, he has a long position of 10. By 65438+February 17, investors saw the futures price rising, so they sold six lots of 65438+ 10 stock index futures at the price of 14 15 to close their positions. After the transaction, the actual position of the investor is only four long positions.
It should be reminded that investors must indicate whether to open positions or close positions when issuing trading orders. If an investor sells 6 open positions of 1 stock index futures at the time of filing on February 7, 2007, after the transaction, the actual position of the investor is not the original 4 long positions, but 10 long positions and 6 short positions.
