Hello, generally speaking, the coal market you mentioned may be the spot market, which is relative to the futures market. They are very close, but there are also many differences.

In the long run, the spot market price and the futures market price should be roughly the same, or roughly the same, but because of the relationship between supply and demand, or because of people's emotions, the price fluctuation in the futures market is very intense, generally exceeding the spot price or lower than the spot price, which is normal.
