Every futures company (or different customers) is different. The following are for reference (standards for each batch):

Corn 3 fuel 3 wheat 3 meal 5 glue 7 aluminum 7 beans 6 cotton 8 palm oil 6 copper (contract value) 2.5%% rapeseed oil 5 sugar 6 soybean oil 6 PTA6 plastic 9 gold 50 zinc 15 yuan.

Opening positions on the same day and closing positions on the same day (Ping Jin) are free.

For each batch of corn (10 ton), the current contract amount is about1.600×10 =1.6 million yuan. If the margin rate is 10% and the margin is 1.600 yuan, the opening of the transaction is the handling fee of 3 yuan (no other fees are required).

That is to say, with 1.600 yuan (margin), you can buy and sell futures with 1.600 yuan, and you only need 3 yuan handling fee to close the position on the same day.
