Asking such a question shows that you don't know anything about futures. 1. Tang Zheng's main contract is 1309, so it can't do futures at all. Futures only do the main contract, not the main contract, and there is no financial concern at all; 2. In China, futures companies are not allowed to do proprietary trading, but can only do economic business. The position you see is the position of futures company customers; There is no banker in the futures market, because theoretically the market can expand infinitely and there is no main force to control the market at all.
