Today's settlement price is 2362 yuan per ton, multiplied by each lot 10 ton, and 23620 yuan is the contract value.

Based on the minimum deposit of 5%, 5% of 23,620 yuan is 1 18 1 yuan, which is the deposit required for trading 1409 first-hand corn contract.

Every contract has a delivery time, which is different from the delivery time of stocks. 1409 contract is delivered in September, as shown in the above figure ... the first trading day ... the sixteenth trading day, the closer to the delivery date, the higher the deposit, which is a means to control the risk of approaching delivery. Generally, there are no speculators involved, so don't worry.

Increase the margin by changing the position: the bigger the position, the more active the speculative funds and the more active the transactions, which is prone to extreme trends, which is also a means of risk control.

I hope the above can help you.
