Do you often encounter the following questions: how much allowance is needed to make first-class rebar, and how to calculate the first-class thread allowance?

The concept of deposit can be searched in Du Niang, so I won't go into details here. The margin we mentioned when we opened the position is called trading margin, which is "how much is the first line" in non-professional terms.

Calculation formula: n lots * transaction price * margin ratio * trading unit.

There are two nouns in this formula that need to be explained!

First, the margin ratio is stipulated by the exchange. Under normal circumstances, futures companies will add certain points on the basis of the minimum margin stipulated by the exchange. For example, the minimum margin stipulated by the rebar exchange is 9%, so the margin that the futures company may charge is between 9- 15%. Bian Xiao has something to say here. The deposit is a double-edged sword, not the lower the better. Although low margin can amplify leverage, it will also amplify risk. Then Bian Xiao posted the margin ratio of all listed futures varieties here for your reference.

Second, marketing unit, what is marketing unit? Generally speaking, it is how many tons per hand, or how many grams per hand and so on. There are too many kinds of futures, which may be a little troublesome to remember. Bian Xiao specially listed a table here for your reference.
