The significance of parameters is reference. System parameters are very rigid and the same, but the trend of each stock is different, which will cause parameter distortion. Therefore, the parameters must be corrected. Secondly, the corrected parameters can reveal the true trend of individual stocks: there are two methods for correction: 1) shortening the parameters, such as checking whether there is a top or bottom divergence in 60 minutes. Only after correction will it be discovered earlier than others. Generally used to prevent pullbacks after a pull-up. 2) Expand parameters, filter out short-term fluctuations, and focus on the medium- and long-term trends of stocks. Correction parameters vary from person to person. Everyone's habits are different, and the parameters they set are also different.

Only senior investors can figure out a set of parameters suitable for practical operations, and they will not tell anyone else except relatives and friends!
