KDJ Indicator

The KDJ Indicator is a technical analysis tool that is an upgraded version of the Stochastic Oscillator.

It was developed to identify overbought and oversold levels in the market, and it has an additional J line that sets it apart from the traditional Stochastic Oscillator.

KDJ Indicator Overview

The KDJ Indicator oscillates between 0 and 100 and is used to measure momentum in the market.


 It can be applied on any timeframe but is most effective on longer timeframes to reduce market noise.

While the KDJ Indicator can be a useful tool for identifying overbought and oversold levels, it should not be used as the sole basis for making trading decisions.

KDJ Indicator Explanation

The KDJ Indicator is an upgraded version of the Stochastic Oscillator that adds an extra J line.

The J line is calculated as the difference between the smoothed K and D values, and it oscillates between 0 and 100.


The K and D lines in the KDJ Indicator are calculated in the same way as in the traditional Stochastic Oscillator, using the highest and lowest price values over a specified period.

The KDJ Indicator is used by traders to identify overbought and oversold levels in the market. When the J line crosses above the K and D lines, it signals an overbought condition, and traders may take short positions or exit long ones.

Conversely, when the J line crosses below the K and D lines, it signals an oversold condition, and traders may enter long positions or exit short ones.

KDJ Indicator: Buy Condition

  • The KDJ indicator’s value should decline under the threshold of 20
  • To find a rejection, you should wait for the price
  • J line crosses below the oversold level and moves up
  • J line crossing above K and D lines
