If you need the data of futures trading, you need to buy it from the futures exchange, but at present, the data of the exchange is only provided to several major information service providers, such as Shihua, Reuters, Fuyuan, Wenhua Finance and Xinhua Finance. You can buy real-time market data from them.
If you cooperate with futures companies, as long as they agree to provide market data, that's fine, but you can't use this data source for profitable business activities (such as publishing and charging).
Because futures companies can only use these data to provide customers with trading returns, inquiries and settlement services, all ways of publishing data with compensation must be approved by the exchange.
