$XLM
The KDJ indicator is a technical analysis tool known as the Random Indicator (Stochastic Oscillator). It is used to identify short-term market trends, evaluate price momentum, and detect overbought and oversold areas. [1, 2, 3, 4]

Components of the KDJ indicator

The indicator consists of three main lines: [1]

K line: represents the position of the current price relative to the trading range over a specified period, and is characterized by its quick response to price changes.

D line: is a moving average of the K line, and works to smooth out fluctuations to determine the overall trend more accurately.

J line: represents the divergence or deviation between the K and D lines (J = 3K - 2D). It often indicates strong and early signs of trend reversals. [1, 2]

How to read and use the indicator

Overbought and oversold zones:

If the values rise above the 80 level, this indicates an overbought zone (a higher likelihood of price falling or a correction).

If the values drop below the 20 level, this indicates an oversold zone (a higher likelihood of price rising or bouncing). [1]

Buy and sell signals (crossovers):

Buy signal: when the K line crosses upward to break through the D line from below (especially when below the 20 level).

Sell signal: when the K line crosses downward to break through the D line toward the downside from above (especially when above the 80 level)
