Negative numbers may be values calculated by the system. Through this matter, we should learn from experience, trade carefully and invest carefully. Futures are not easy to do, be careful because no one buys crude oil, but crude oil is still being produced continuously. So ... give you money to take away, so there is a negative number, which means to post money backwards. Because the global economy has pressed the pause button, the demand side of oil has shrunk seriously, and the supply side far exceeds the demand and storage of oil. At this time, there is no buyer in the market. According to the rules, the contract must be delivered when it expires. Futures companies can't really deliver these crude oils. The transportation cost and storage cost alone are higher than this futures price, and they don't need it. They can only throw orders like crazy and deal with these futures contracts like garbage. This is the fundamental reason why crude oil futures prices will be negative.
