I think most people will make money from their own accounts, and it is estimated that there will be less when they make orders, but they will return the departments that lose money! Therefore, we all suggest that when we earn 20%, that is, when we earn 20%, we should recover the profits, so that the costs can be recovered slowly, and we should still keep the original account positions for trading when making orders. I won't regret making money in front and exploding behind! I didn't know whether it was a profit or a loss until I took it out.
