Crude oil delivery refers to the act of converting crude oil futures contracts into physical crude oil. After the contract expires, investors can choose to deliver or close their positions. Ordinary investors will not choose physical delivery, and investors will reverse their positions.

Crude oil trading also earns the difference by buying and selling, which can be operated in two directions (T+0), without price limit, and can be bought and sold at any time during trading hours, with the minimum trading unit of 0.0 1 lot.
