The minimum fluctuation price refers to the smallest unit of price change of the subject matter in the futures contract, also known as the lowest price or minimum jump. Different futures varieties and transactions have different minimum variable prices. For example, the lowest fluctuation price of copper futures contract in Shanghai Futures Exchange is 10 yuan/ton, while the lowest fluctuation price of gold futures contract in Chicago Mercantile Exchange is 0. 1 USD/oz. In futures trading, the minimum price change is very important for investors' profit and loss. If the price change exceeds the minimum change price, investors can make profits or bear losses. Therefore, investors need to know the minimum change price of the futures they trade, and make appropriate trading decisions according to market conditions.
