If it is confirmed, it depends on which one has the chance to enter that one, but this will involve the issue of funds. If you choose this method, you must have a lot of money. If you buy three varieties at the same time, the operating capital should not be greater than 50%-60% of the total capital, which will increase your risk. If you want to do it in the day, you should also pay attention to your mentality, because the above three varieties fluctuate greatly in the day, such as sugar. If you look at it today, blindly chasing the empty space and chasing more, then you will definitely lose money today, and such a variety with large fluctuations will certainly be able to hold the list. You must know when to resist and when to cut the meat. Keeping a good attitude is the basis of your profit. At the same time, pay attention to the timing of operation and stabilize your mind. Don't be washed away by the big fluctuations in the day. Success belongs to the persevering.
