What Is KDJ Indicator? Its Impact On Stock Market

KDJ Indicator

The KDJ index, often known as the stochastic index or random indicator, is a relatively new and useful technical analysis metric. It was created with the sole objective of maximizing the efficiency of your trading efforts, and it is well worth your time. KDJ can assist you in determining the trend’s direction as well as the best entry spots.

KDJ may appear similar to the Alligator and the Stochastic Oscillator to those familiar with basic technical analysis tools. And, like the previous two, it aids in determining trend direction/strength and appropriate entry points. In short, we can examine and forecast changes in stock trends and price patterns through this technique.

Working of KDJ

The KDJ is made up of three lines that are referred to as the K, D, and J. As you can see, the name is straightforward and is derived from the indicator’s curves. The J is brand new and shows how the D value differs from the K value. The KDJ is calculated based on the highest price, the lowest price, and the closing price. The obtained K, D, and J values are each produced at a point on the index’s coordinate, and an unlimited number of such points are connected.

It is primarily a technical instrument that employs genuine price volatility to reflect the strength of price moves, as well as overbought and oversold conditions, and to generate trade alerts before prices have increased or fallen. Oversold and overbought levels, like the Stochastic Oscillator, indicate moments when the trend is likely to reverse. These thresholds are set to 20 percent and 80 percent by default. Both can be tweaked to increase sensitivity and reduce the number of false alarms. As a result, it may be appraised swiftly, intuitively, and fast.

The KDJ line is more accurate for grasping the short- and medium-term market because it is essentially a concept of random oscillations. No matter what trading technique you use, first, you need to learn how the indicator works. Once you grasp the nature of the indicator, it will be easier to spot noise signals, which occur when the indicator alerts you to an entry point but the signal is bogus. You can also assess which order is superior (because not every entry points have a high winning probability if only depending on the indicator).

Calculating KDJ

You don’t need to know how to program an indicator to use it, but you do need to know when it will appear on the price chart. Drawing your hand according to the formula of those indicators is sometimes the best thing to do.  The KDJ computation is more difficult. Calculate the RSV value of the period (n, n, etc.) first, which is the immature random index value, and then the K, D, J, and other values. To get the daily KDJ value, use the following formula:

  • n day RSV=(Cn-Ln)(Hn-Ln)100

The closing price on an nth day is Cn; the lowest price in n days is Ln, and the highest price in n days is Hn. RSV almost always has a value between 1 and 100. Secondly, we calculate the D and K values:

  • Day K value = 2 / 3 × the previous day K value + 1/3 × day RSV
  • Day D value = 2 / 3 × previous day D value + 1/3 × day K value

In situations where K and D values are absent on the previous day, 50 can be used.

  •  J value = 3(day K value) – 2(day D value)

Setting up a KDJ

The indicator can be set in four simple steps: First of all, you will select ‘Indicators’ and then the ‘Trend’ tab on the screen. Next, you will choose KDJ from the list of available options and lastly click Apply without making any changes to the settings.

KDJ’s Applications

The KDJ indicator was first employed in futures market analysis, and it is now commonly utilized in stock market short-term trend research. In the futures and stock markets, it is the most widely used tool for technical analysis. It is simply understood by both experienced and rookie technicians, and it tends to assist all investors in making sound entry and exit decisions on their holdings.

Trading with KDJ

In trading, the KDJ indicator is used to determine the best time to open a buy or sell transaction. When the wires cross over at a given point, the signals are received. A golden fork and a dead fork are two terms often used to describe these moments. When trading with KDJ, you want to receive two sorts of signals. When the three lines converge above the overbought level, with the blue line above the yellow line and the yellow line above the purple line, you should consider selling the asset.

When the lines converge below the oversold level, with the blue line above the yellow one and the yellow line above the purple one, buying should be considered. However, the KDJ generates erroneous signals but combining it with another indicator like the Average True Range (ATR) or the Average Directional Index (ADX) can be a smart idea. Many inexperienced traders believe that trading is so straightforward that all they have to do is use an indicator to look for trading signals and then push a button.

If trading were truly that straightforward, there would be far fewer traders who consistently failed and went bankrupt. One of the most common reasons for traders’ failure is that they place too much reliance on indications when trading. Even though indicators display data, it’s vital to remember that how that data is interpreted is highly subjective. Keep in mind that no indicator is able to provide you with 100% accurate signals. As a result, it’s always a good idea to take a step back and assess whether your personal prejudices are influencing your decision-making. What one trader sees as a clear buy or sells signal may be nothing more than market noise to another.
