The SSK indicator using a divergence line
The KDJ indicator is actually a derived form of the Slow Stochastic with the only difference being an extra line called the J line. The J line represents the divergence of the %D value from the %K. The value of J can go beyond [0, 100] for %K and %D lines on the chart.
Divergence calculation = 3* SSK – 2* SSD
The red and blue lines are standard Slow Stochastic while the green line is the J line.
