Is the futures heavy position yield high or the open position yield high?
Great gains. The risk of futures light warehouse is small, but the profit space is limited, and the profit space of heavy warehouse is large, but the risk is relatively large. Improper operation of heavy warehouse will lead to warehouse explosion. Futures, relative to the concept of "spot", refers to the delivery and trading of commodities that are bought and sold now but will be carried out in the future.
