KDJ indicator is a very good indicator, its advantage lies in its sensitive response, and it can give a very obvious buy and signal. However, it also has a scope of use. Usually, when the stock price or index runs in a certain range of boxes, KDJ indicators will send out very accurate import and export signals. According to low gold delivery replenishment, high gold cross shipment is very accurate. The obvious deficiency of KDJ index lies in its sensitivity: its response is so sensitive that users either buy prematurely or ship prematurely and return empty-handed. This is the so-called passivation problem of KDJ index at high and low positions.

It can be seen from the calculation formula of RSV that as long as the closing price of the day is not the highest price, the RSV value of the day is not equal to1; As long as the closing price of the day is not the lowest price, the calculated RSV is not equal to 0. Therefore, the passivation of KDJ indicators in high and low positions will be inevitable. Especially in very strong or weak markets, namely, unilaterally rising markets and unilaterally falling markets, KDJ indicators may be passivated and re-passivated. Therefore, we can't sell because the KDJ indicator is passivated at a high level and buy at a low level.

The following methods can effectively solve the problem of KDJ index passivation cheating:

(1) Verification method: Because KDJ indicators are very sensitive, they often give some wrong signals, which easily mislead investors and lead to operational errors. If we put these signals into the analysis chart with longer time period for verification, so as to confirm the reliability of these signals, we will get better guidance effect. For example, when the KDJ indicator is passivated at the high position of the daily chart or there is a dead fork, go to the weekly K chart to check its reliability. If the KDJ indicator on the weekly K-line chart shows that this round of rising market will continue, the KDJ dead fork on the daily K-line chart is invalid.

(2) Morphological method: Because the KDJ indicator is very sensitive, the indicators it gives are usually very advanced, so we can help us find the correct trading point through the shape of the KDJ indicator. KDJ indicator will replenish when the low position forms W bottom, triple bottom and head and shoulder bottom or "aerial refueling" form; In a strong market, when KDJ indicators form M-head shape and head-shoulder shape at a high level, the reliability of signal transmission will be stronger at this time.

These can be understood slowly. There is no 100% successful strategy in the stock market, only reasonable analysis. Every method and skill has its application environment and the possibility of failure. Novices should not use Niugubao mobile phone to fry cattle in the cattle list when they are not sure, which is much safer. I hope I can help you, and I wish you a happy investment!
