Outer market refers to futures trading markets in other countries, such as LME and COMEX, such as soybeans. Because there are more domestic soybean imports, the domestic market is greatly influenced by the external market, so many times the domestic market follows the trend of the external market, but domestic self-sufficient commodities, such as sugar, will go out of the small bull market and will not follow the external market.

The outer disk can be seen in the futures markets such as Wenhua Finance, Bloomberg and Fuyuan.
