5 Minutes to Learn Trading | How to Use the Random Indicator (KDJ) to Trade Crypto Assets Reasonably

The Random Indicator (KDJ) can assist traders in identifying potential market trends. One of the functions of this indicator is to show the overbought and oversold market conditions. To obtain more reliable signals, it is recommended that traders combine the KDJ indicator with other technical analysis tools, such as the Average Directional Index (ADX) and the Average True Range (ATR). It is worth noting that the KDJ indicator often gives false signals in range-bound markets. Gate offers a variety of technical analysis indicators, including the KDJ indicator, for traders to choose from.

Regardless of how the trading market operates, it is extremely important to maintain profitability through wise decisions. In addition to relying on a reliable trading platform, traders must possess a mature set of technical analysis tools. These indicators serve different purposes, such as predicting trends or showing the momentum of asset increases or decreases. Most of these indicators can assist traders in analyzing and understanding trading charts. This article will focus on the Stochastic Indicator (KDJ).

What is the Random Index (KDJ)?

The Random Indicator (KDJ), also known as the Random Index, is a technical analysis tool used to measure the momentum of assets, indicating their overbought and oversold conditions. As a trend-following indicator, KDJ helps traders identify the best points to buy and sell.

It should be noted that the KDJ indicator is derived from the stochastic indicator. However, the stochastic indicator only has two lines, namely the K line and the D line. As can be inferred from the name of the KDJ indicator, this indicator has three lines: the K line, the D line, and the J line, each of which plays an important role in identifying overbought and oversold conditions.

The speeds of the K line, D line, and J line vary, making them very useful for predicting trends and momentum. The K line moves the fastest, while the D line moves the slowest. The J line is in the middle, neither fast nor slow. In most cases, the D line is displayed in blue, the K line in yellow, and the J line is usually displayed in red or purple. However, the specific colors may vary depending on the platform you are using.

The J line represents the deviation of the D line and the K line, which means that the J line represents the difference or margin between the D line and the K line. It is usually calculated based on the lowest and highest prices of the asset as well as the closing price for each period to derive the KDJ indicator. The K line, D line, and J line are shown in the figure below:

As shown in the figure above, the K line, D line, and J line have intersected several times.

The operating principle of the Random Indicator (KDJ)

Similar to the KD indicator, the KDJ indicator also has a value range from 0 to 100. It should be noted that the value of the J line can exceed 100 or fall below 0. However, most trading software systems have values between 0-100.

When the KDJ value is between 80 and 100 (including 80 and 100), it indicates that the asset is overbought. Conversely, a value less than or equal to 20 indicates that the asset is oversold. However, each trader can set their own preferences for overbought and oversold areas. Typically, the area between 20 and 80 is called the wandering zone, and the values in this zone have little guiding significance when making trading decisions.

How to use the Random Indicator (KDJ)

In general, when three lines intersect, it indicates that this is a suitable trading opportunity. For example, when the three lines converge in the overbought area, the KDJ indicator shows a sell signal at this time. Additionally, a bearish trend in the K-line chart can also indicate a sell signal. A bearish crossover line indicates a potential sell signal, as shown below:

As shown in the figure above, there is a crossover point in the overbought area at the selling point. At the same time, the downtrend of the K-line chart above the stochastic indicator can also confirm the selling point.

Buy Signal
When the three lines converge in the oversold area, the KDJ indicator shows a buy signal. Just like the overbought area, the oversold area also indicates a high possibility of price reversal. However, a wise approach is to combine the KDJ indicator with other tools, such as the Average Directional Index (ADX) and the Average True Range (ATR).

The above figure shows the sell signals and buy signals. It should be noted that at the sell signal point, the blue line is at the bottom, the yellow line is in the middle, and the purple line is at the top. The order of the lines for the buy signal is different; at the buy signal point, the blue line is at the top, the yellow line is in the middle, and the purple line is at the bottom.
