The income sources of futures investment include spread and hedging. For the spread income of funds, the margin ratio of exchanges to futures companies is generally 5%-8%, and the margin ratio of futures companies to customers is 3 percentage points higher than that of exchanges according to regulations. When the customer funds of futures companies are large, the amount of 3% is very large. Moreover, the futures margin is different from the customer margin in the stock market. It does not pay interest to customers (because of overdraft trading factors), but the exchange pays interest to the funds (not holding positions) of the futures company.
