FAQ
What is the difference between KDJ and the Stochastic Oscillator?
KDJ is an extension of the Stochastic Oscillator. The primary difference is the addition of the J line (calculated as 3D - 2K), which makes the indicator more sensitive to price fluctuations and better at identifying extreme market conditions.
How should I interpret the J line when it goes above 100 or below 0?
The J line represents momentum. When it exceeds 100, it suggests an extreme overbought state where a price correction is likely. When it drops below 0, it indicates an extreme oversold state, suggesting a potential upward reversal.
Is KDJ reliable in a strong trending market?
KDJ can be less reliable during strong trends because it may stay in overbought or oversold territory for long periods (indicator embedding). It is best used for timing entries in the direction of the trend rather than trading against it.
