The combination of KDJ indicator and bollinger band can make the signal of KDJ indicator more accurate. At the same time, because the bollinger band index in the daily K-line index system often reflects the medium-term running trend of the price, it is very useful to use these two indicators to judge whether the price fluctuates in the short term or in the medium term, especially suitable for judging whether the price peaks (bottoms) in the short term or rises (falls) in the medium term, and the effect is very good.
I hope I can help you.
