Is it a futures company, not a futures company? Maybe you should stare at the outer disk and see the trend of the futures on the outer disk, and then refer to the domestic disk of the futures on the next day according to the trend; Also, in terms of time, you can ask clearly whether that company engages in external futures. Other nights related to futures should be nothing.

This has nothing to do with arts and sciences, right? As long as you are interested in this and willing to learn this, you can adapt. Good luck! !
