1, and the supply pressure refers to the output of this variety in the futures market. Such as soybean, corn, copper and rubber.

Pressure on general output means that supply will increase and futures prices will decrease. On the contrary, if the output is low and there is no pressure on supply, futures prices will rise, for example, forcing the market to empty.

2. Inventory pressure There are two concepts, one is the inventory of warehouse receipts registered by the exchange, and the other is the national inventory. In this respect, the supply is sufficient, the price will not rise, and the national stocks will sometimes be sold as planned, which will also affect the price fluctuation in the futures market.

3, the demand pressure is easy to understand, everyone wants to buy this commodity, and the price of this commodity will definitely rise. However, if the inventory and output of this commodity were small at that time, it is conceivable that the demand pressure was great. This will affect the price to continue to rise.
