Q: It is easy to buy but difficult to sell. I know when to buy but not when to sell. It is a headache!
Answer: The principle of buying and selling is the same. If you are not used to it, then look at the trend chart in reverse, so that you can use the buying point thinking to grasp the selling point. Of course, the final solution is to grasp both the buying and selling points, without bias. The structure of any level of graphics is the same.
