First of all, each variety has different financial attributes. However, each variety exchange stipulates the maximum daily amplitude, that is, the price limit. Almost every one of these varieties is about 5%.

In order to have a relatively large range, I personally think that two basic conditions are needed: 1, and the goods have sufficient financial attributes; 2. Commodity prices need a fierce price war between long and short sides.

Judging from the trading data of the two, the trading volume of zinc is much larger than that of aluminum, which provides the necessary conditions for its strong amplitude.
