Because futures are not like fund stocks, you can have as much as you want. It pays the trading margin. For example, soybean futures 10 ton/lot, with 8% margin per lot. The margin you need to pay is = price per lot * several lots *8%, which will greatly improve the utilization rate of funds, but it should be noted that the risk of futures is quite large and you need to be very careful. If you have just stepped into the futures market, you can find a relatively reliable investment consulting company to open an account, because you can get some free guidance and advice when you open an account there.
I hope you succeed,
