Thank you Professor @asaj . Actually I have tried to provide additional information for this course by presenting a good presentation, especially in the calculation section. I've illustrated calculations with actual case examples that may not have been in this course. I also present a complete explanation of KDJ just by looking at one chart, as seen in the chart picture in the first question and the conclusion section because I am trying to find a complete chart so that readers can easily understand it in one chart picture.
