5% margin is the standard given by the exchange to futures companies under normal positions, but it also stipulates that the standard for futures companies to collect margin from customers shall not be lower than that of the exchange.

Relatively speaking, the reputation of futures companies is better than that of customers, and the risks are more controllable. In order to better control risks, futures companies will generally raise the margin collection standard 1 times on the basis of the exchange, because the exchange will adjust the margin collection standard at any time according to factors such as the number of positions and the approaching delivery month of the contract.

Taking copper as an example, assuming that the total amount of bilateral positions is n, the standard of deposit collection for general monthly contract exchanges is as follows:

N<= 1.2 million lots, with a deposit of 5%.

1.20,000 lots < n < =140,000 lots, and the deposit is 6.5%.

140000 lots

160000 lots < n, and the deposit is 10%.

The contract is charged at different time periods according to the following standards:

7% from the 10 trading day in the second month before the delivery month;

From the first trading day of the first month before the delivery month,10%;

From the 10th trading day of the first month before the delivery month,15%;

20% from the first trading day of the delivery month;

From the first two trading days of the last trading day, 30%.

When other circumstances occur at the same time, the fees will be charged according to a higher standard. From the 10 trading day of the second month before the delivery month, if the total number of bilateral positions exceeds160,000 lots, it will be charged at 10%.

There are many standards for the position margin ratio of various exchanges and varieties.
