Did you ask that question yesterday? I don't want to answer anonymous help. Such a question shows that you don't understand futures at all. "For example, now that the futures contract you buy and sell has risen to 2 million, you need a deposit of 200,000 yuan"-this sentence is true; "And your account only has * * *150,000 yuan, so the deposit is insufficient." -This mistake, because futures are settled without debt on a daily basis, the contract has risen to 2 million (of course, one day is impossible, because there is a price limit system, just taking you as an example)-Except for your own margin, the profit will arrive immediately, and your book will increase by 65,400. Futures is a zero-sum game. If you make the right profit, you will inevitably lose money. The exchange will directly transfer funds from the loser's account to your account. Now your book is 1 15000, there will be no shortage of deposit, and there will be an extra 950000.
