Derived from a security's closing price relative to its recent high-low range, the KDJ helps traders find short-term trading opportunities by providing buy/sell signals based on line crossovers and by signaling extreme market conditions when lines reach 0 or 100.&#x20;

* **How to calculator KDJ indicator:**

> Parameters: KDJ(RSV Period, K  Period, D Period)
>
> *Example: KDJ(9,3,3) calculation for Day chart*
>
> > **RSV** = (Current closing price - 9-day minimum value)/(9-day high price - 9-day minimum value) ×100
> >
> > **K** = SMMA (RSV, 3)
> >
> > **D** = SMMA (K, 3)
> >
> > **J** = 3K - 2D
