So I just don't set a stop loss, hehe. Why not? It is because I saw that some seniors/seniors did not set a stop loss. Not only did they not rush positions, but they also made a lot of money. Now many seniors suggest putting a stop-loss price, so I learned to set it. I can only find obvious resistance support. It is a big stop loss at present. There is no way. It should be improved with more experience in the future.
