Of course, if you are a master, you can do it without losing money in the long run.
If you want to lose less, you need to do it, such as better position control, better fund management, firm stop loss, and better analytical ability. The most important thing is to realize it. It will take many years for most people to realize it. I have been doing futures 1 for many years, but I still feel that I can't.
Your question is really a long story. Open a tens of thousands of accounts first, sum up a lot, it takes time and your own efforts to become a master.
PS: Among the futures varieties, I feel that corn is the smallest ... the market fluctuates little. Hehe, a risk-averse person like me doesn't like this variety.
