How does KDJ indicator work ?

KDJ indicator MT4 is quite hard to understand, Newbies should not use, because they may make tragic mistakes. It is constructed using 2 sub-components: lines and levels. The lines are 3: The K-line, the D-line, and the J-line. The levels are 2: Overbought level and Oversold level. We’re going to explain these sub-components in detail, starting with the lines:

  • The K-line: Represents the fastest line. It shows the percentage value of the last Closing price about the total chosen price range.
  • The D-line: It is slower than the K-line. It’s a simple moving average (SMA) of the K-line.
  • The J-line: Represents the slowest line. It is a signal line of the divergence of the percentage D-value from the percentage of the K-value.

On the other hand, we have 2 levels: The overbought level and the oversold level.

  • The overbought level: the level at which a security believed to be trading at a price level above its fair value. Generally, professional traders assign an 80% value for this level.
  • The oversold level: the level at which a security believed to be trading at a price level below its fair value. Generally, professionals assign a 20% value for this level.
    Note that the KDJ lines aren’t limited to 100%, they could surpass it!

Therefore, we should have the following results:

How to read KDJ indicator ?

Well! the decision rule is simple yet quite hard to detect and it needs a lot of concentration. Before starting, you should know that the decision rules in MT4 and MT5 are a little bit different than in Tradingview. So, for the MT4 and MT5 platforms the decision rules are as follows:

  • Buy when the 3 lines cross each other below the oversold (20%) level. It’s a signal for a Long position.
  • Sell when the 3 lines cross each other above the overbought (80%) level. It’s a signal for a Short position.

However, the decision rules for Tradingview are as follows:

  • Buy when the 3 lines are below the 20% oversold level and the D-line is above the K-line, and the K-line in turn is above the J-line.
  • Sell when the 3 lines are above the 80% overbought level and the J-line is on top, and beneath it is the K-line and on the bottom is the D-line.

To better understand this, we’re going to apply the decision rules on MT4 and MT5 and then on Tradingview.

  • Example 1

As observed, there are 4 crossing points where there is an opportunity to either enter or exit the market. Cross Points 1 and 3 alerts of an entry opportunity, as the 3 lines crossed each other under the 20% oversold level. Therefore, traders or professional investors should enter a long position so they may lock in the highest possible profit. However, Cross Points 2 and 4 are warning of a possible trend reversal, therefore, traders should Sell at these 2 points or enter a Short position.

Example 11
  • Example 2

In this example, we’re analyzing Apple Inc. Stock on the NASDAQ Stock Exchange market. As observed, in Point 1, the 3 lines are above the 80% overbought level, where the J-line (red) is on top, the D-line (Green) is on the bottom and the K-line (Blue) is in the middle. Which signals the potential trend reversal and alerts users so they may either sell what they own or enter a short position. However, in point 2, the 3 lines went below the 20% oversold level and the D-line (Green) is at the top, the J-line (Red) is at the bottom and the K-line (Blue) is in the middle. This is a signal of a trend reversal as the indicator sent an alert to users so they may buy immediately to secure the maximum possible profit.
