The essence of spot oil is illegal futures. Without any qualifications, the software has a back door, which can manipulate people's ups and downs and then earn the so-called transaction fee. The state has never approved oil futures trading, and importing oil also requires national qualifications. At present, only state-owned enterprises such as Sinopec, PetroChina and CNOOC are qualified. Domestic crude oil belongs to state-owned enterprises, and they can't buy foreign crude oil, which is simply a lie.
