The first difference is that the electronic market of bulk commodities trades in spot, while futures trade in standardized contracts;
The second difference is that the spot trading of bulk commodities in the electronic market is not very strict with the quality and variety, while the variety of futures trading is very strict with the quality and variety of its subject matter.
The third difference is that the supervision unit of the electronic market for bulk commodities is the commercial department, while the supervision unit of the futures exchange is the CSRC.
The fourth difference is that most of the electronic markets for bulk commodities are over-the-counter transactions, while futures exchanges are all on-site transactions, so they are more standardized. And so on.
