Since it is a contract signing, those who are long must be short, and the number of hands is equal.
Buying up is easy to understand. Say buy it first:
This is the case. When you are at 5000 points in stock index futures, it is estimated that you will fall. You can sign a contract with others, stipulating that you can sell the first-hand stock index to him at 5000 points. The first-hand contract amount is 5000× 300 = 1.5 million yuan, and the performance bond ratio is 10%. You paid about 6.5438+0.5 million deposit to the exchange (futures brokerage company).
When the stock index drops to 4000 points, you buy a first-class stock index in the market and give it to the buyer at the price of 5000 points (buy and close the first-class stock index contract), making a first-class profit: (5000-4000) × 300 = 300,000 yuan.
The bull that signed with you (not specifically) lost 300 thousand.
(Ignore handling fee)
Of course, if the stock index goes up, you will lose money.
