How is the profit and loss of stock index futures calculated?
At present, the contract of Shanghai and Shenzhen 300 Index is every point in 300 yuan. Because it is a two-way transaction, the profit and loss lies in the connection between the choice direction and the actual direction. For example, if you open a long position, you will earn 300 yuan every time the index rises 1 point, and you will lose 300 yuan every time it falls 1 point; If you open a short position, the index goes up 1 point, you lose 300 yuan, and go down 1 point, and you earn 300 yuan. In addition, a transaction fee of about 45- 100 yuan will be paid to the futures company for each transaction.
