China Aluminum: 5 tons/lot, deposit 8%, handling fee: 5 yuan/lot.

I don't know what you mean by ratio, but

Futures is a margin system, which means that you can use 1 10,000 RMB to do 1 10,000 RMB business, and 1 10,000 RMB is a margin.

Take aluminum as an example: if you produce more copper, then the deposit you need to pay is

The timely price of aluminum on that day * 1 lot *5 tons/lot * = deposit (the money you need to pay, that is, the money you need to buy aluminum), and the handling fee you need to pay is 5 yuan (provided that the position is closed today, that is, Ping Jin).

General futures companies have a minimum capital of 50,000.

However, this is not very strict. The amount of funds is ultimately controlled according to their own positions, but it is recommended to make more than 20,000 agricultural products and more than 50,000 metals!
