What is the KDJ Indicator? How to use it?
The KDJ Indicator is a technical analysis tool that is used to identify potential buying and selling opportunities in the stock market. It is a combination of three different indicators.
The Stochastic Oscillator, The Moving Average, and The Relative Strength Index (RSI).
In this article, we will discuss what the KDJ indicator is, how it works, and how you can use it to make informed trading decisions.

KDJ Indicator???? ????
The KDJ indicator is a momentum oscillator that was developed by George Lane in the 1950s. It is similar to the stochastic oscillator in that it measures the speed and direction of price movements. However, the KDJ indicator also incorporates a moving average and the RSI to provide a more comprehensive view.
The KDJ indicator is particularly useful for identifying market trends and potential reversals. By analyzing the relationship between the current closing price and the highest high and lowest low over a specified period of time, traders can gain insights into the momentum and direction of price movements.
Additionally, the KDJ indicators shows overbought and oversold levels can help traders identify entry and exit points for their trades. Overall, the KDJ indicator is a valuable tool for technical analysis and can be used in conjunction with other indicators to make informed trading decisions.
How Does the KDJ Indicator Work????? ???? ????
The KDJ indicator is calculated using the following formula
- K(fast line) = (Current Close – Lowest Low) / (Highest High – Lowest Low) * 100
- D(signal line) = 3-day simple moving average of K
- J(slow line) = 3-day simple moving average of D
The K line represents the percentage of the current closing price in relation to the highest high and lowest low over a specified period of time.
The D line is a 3-day simple moving average of the K line, and the J line is a 3-day simple moving average of the D line.
The KDJ indicator is plotted on a scale of 0 to 100, with readings above 80 considered overbought and readings below 20 considered oversold.
Traders can use these levels to identify potential buying and selling opportunities.
How to plot the KDJ Indicator in a TradingView chart?
The KDJ indicator is not readily available in TradingView’s default indicator set. However, it can be manually added or implemented using custom scripts and coding available within the TradingView platform.
- Open your trading platform (here we have used TradingView).
- Click on Pine Editor.
- Just Copy and paste the given Script
//@version=5
indicator(“Custom KDJ”, overlay=true)
// Input parameters
length = input(9, title=”Length”)
smoothK = input(3, title=”Smooth %K”)
smoothD = input(3, title=”Smooth %D”)
// Calculate %K
lowestLow = ta.lowest(low, length)
highestHigh = ta.highest(high, length)
rsv = (close – lowestLow) / (highestHigh – lowestLow) * 100
kdj_k = ta.sma(rsv, smoothK)
// Calculate %D
kdj_d = ta.sma(kdj_k, smoothD)
// Calculate %J
kdj_j = 3 * kdj_k – 2 * kdj_d
// Plotting
plot(kdj_k, color=color.blue, title=”%K”)
plot(kdj_d, color=color.red, title=”%D”)
plot(kdj_j, color=color.green, title=”%J”)

How to Use the KDJ Indicator???? ????
The KDJ indicator is a versatile tool that can be used in a variety of ways to make trading decisions.
Certainly! Let’s apply the provided information to the scenario of purchasing UNI/USD
Scenario: Purchasing UNI/USD
1. Current UNI/USD Price
Today’s cost per UNI/USD: $7.37
2. Previous Close Price
Previous day’s closing price: $7.25
3. Previous Day Price Range
Lowest price in the previous day: $7.25 (previous close)
Highest price in the previous day: $7.45
4. Relative Strength Value (RSV) Calculation
RSV = (Current Price – Lowest Price) / (Highest Price – Lowest Price) × 100
RSV = (7.37 – 7.25) / (7.45 – 7.25) × 100
RSV = 0.12 / 0.2 × 100 = 60
Therefore, the RSV of UNI/USDT is 60.
5. Interpreting RSV
A higher RSV (60 in this case) suggests that the current price is closer to the highest price of $7.45 on the previous day. This means the closing price is higher than the lowest price of $7.25.
6. Calculating K and D Values
Assuming the previous day’s K and D values are available:
Day K Value = 2/3 × Previous Day K Value + 1/3 × Day RSV
Day D Value = 2/3 × Previous Day D Value + 1/3 × Day K Value
J Value = 3 × Day K Value – 2 × Day D Value
If there are no previous-day K and D values, you can start with 50 as a base.
By calculating RSV, K, and D values, this process helps in understanding the momentum and trend of UNI/USD prices. It provides insights into whether the current price is moving towards recent highs or lows, aiding in informed decision-making in the market.
One strategy is to look for divergence between the price of a security and the KDJ indicator. If the price is making higher highs while the KDJ indicator is making lower highs, it could indicate a potential trend reversal.
Another strategy is to watch for crossovers between the K line and the D line. A bullish crossover, when the K line crosses above the D line, could signal a buying opportunity, while a bearish crossover, when the K line crosses below the D line, could indicate a selling opportunity.
Additionally, traders can use the overbought and oversold levels of the KDJ indicator to identify potential entry and exit points for their trades.
By combining these strategies with other forms of analysis, traders can make more informed trading decisions using the KDJ indicator.
The KDJ indicator can be used in a variety of ways to make trading decisions.
Divergence
Divergence occurs when the price of a moves stock/currency in the opposite direction of the KDJ indicator. This can be a sign of a potential trend reversal.
For example, if the price of a stock is making higher highs, but the KDJ indicator is making lower highs, it could indicate that the stock is losing momentum and may soon reverse.
Crossovers
Crossovers occur when the K line crosses above or below the D line. A bullish crossover occurs when the K line crosses above the D line, indicating a potential buying opportunity. A bearish crossover occurs when the K line crosses below the D line, indicating a potential selling opportunity.
Golden Cross
The golden cross, which is a buying signal, is what happens when the graph’s K line crosses over the D line. Additionally, the short-term buy signal is more accurate when the K and D lines cross upward below 20; if the K value is below 50 and crosses above the D value twice, making a higher high golden cross “W” pattern, there may be a significant increase in the stock price in the prognosis for the market.
Death Cross
A cross occurs when the K value is declining and breaks below the D line from above. This is typically interpreted as a sell signal. Moreover, the short-term selling signal is more precise at this moment when the K and D lines cross below an 80 level. A significant decrease in stock prices may be in store for the market if the K value is above 50, crosses below the D line twice in a trend, and originates from a lower low death cross “M” pattern.
Overbought and Oversold Levels
As mentioned earlier, readings above 80 on the KDJ indicator are considered overbought, while readings below 20 are considered oversold. Traders can use these levels to identify potential entry and exit points for their trades.
Limitations with the KDJ
The primary drawback of the KDJ is its capacity to produce erroneous signals in unstable markets. Due to its price sensitivity, the KDJ could produce a false trading signal, causing the price to move in the opposite direction of the signal and resulting in unsuccessful trades.
Conclusion
The KDJ indicator is a useful tool for traders looking to identify potential buying and selling opportunities in the stock market. By incorporating multiple indicators, it provides a more comprehensive view of market trends. However, like any technical analysis tool, it should not be used in isolation and should be combined with other forms of analysis for more accurate results.
