Sometimes it is the loss caused by market fluctuation, and sometimes it is because of my own greed. I always want to earn more and earn more, and the final result is a lot of losses. There is also your own misjudgment. If you do futures yourself, you must practice all aspects of technical analysis and insist on reading and learning. But now there are a lot of programmed software. You don't need to know much about futures technology, just know how to use it and how to set it up. Then know the function of this software. It is more suitable for people who don't understand futures or just do futures.
