If you don't count the middle ups and downs, 2 100 buys 2400, which is 10 hand A goods, earning 300 points.
2 100 points are not necessarily 2 1000 deposits. Let me explain to you:
Now there is a condom in the supermarket for 100 yuan. If you compare supermarkets to futures markets and condoms to commodities, you only need 10 yuan to buy them, and this 10 yuan is your deposit. Do you understand?
When this condom rises to 200 yuan overnight, you can earn 100 yuan by selling it, and you only spend 10 yuan.
This is the leveraged trading of futures, with small bets and big bets.
