In the help section of the technical indicators, there is a section for the KDJ Stochastics indicator. While the explanations for the K and D parameters are provided, there is no explanation for the J parameter. Therefore, I would like to request the addition of an explanation for the J parameter.

When dealing with US stocks, the SEC issues reports such as financial statements. There are personal blog sites that handle Form 8-K (Current Report), Form 10-Q (Quarterly Report), Form 10-K (Annual Report), etc. in detail, but I haven't seen many sites that handle how to read SC13GA (mass holdings reports), etc., and it's a point that I personally struggle with, so it would be great if Moomoo could make a reading course, etc. Thank you very much.
