You just opened an account, right? I advise you to do it with a simulation disk for half a year, and then with a real disk. Remember what I said when you lose money. Corn 1500 yuan is a little more, which is also the cheapest variety in futures. According to the calculation of at least 1500 yuan, you should keep at least 200 yuan balance in your account to prevent losses. If your account turns negative, you may be forced to close your position, that is, you need at least 1700 yuan to make corn, or even 2000 yuan. Five hundred dollars can do nothing. The leverage of one to ten is good, but the price of corn is one ton. Will you understand?
