It provides an important reference standard for metal prices across industries, institutions and investors. Investors can use LME indicators to understand the price fluctuation trends of various metals, grasp market changes and trends, and make corresponding investment decisions.

In general, the LME indicator is an important indicator that reflects the trend of price changes in the global metals market. By calculating the weighted average of the prices of futures contracts listed on the London Metal Exchange, it provides valuable reference information to help investors judge market changes and trends so that they can make corresponding investment decisions.
