There are also raw material costs, industry policies and demand policies. Of course, there are futures prices now.
Futures and spot interact with each other and are converted in different periods. For example, when the price deviates far from the spot, the spot will affect the futures (tend to fall), and when the futures price falls below the cost price, the spot will affect the futures (tend to rise).
But for futures, spot is only one of the factors that affect price fluctuation, as well as macroeconomic and monetary policies, raw material costs, accidents and so on. Founder futures marketing department.
