I am not from China Eastern Airlines. Generally, futures companies add about 3 points on the basis of the exchange. If you are a newcomer, I suggest that you don't need too low margin, which may sometimes cause you huge losses. In the futures market, you can never make enough money. So there is no need to eat fatty in one bite, take your time! And you should be prepared for losses in the early stage.

I hope you can do something in the futures market ...
