KST Indicator

The KST indicator can be used in the same manner as many other momentum oscillators, such as the well-known relative strength index (RSI). Trading signals are generated when the KST crosses over the signal line, but traders may also look for convergence and divergence with the price, overbought or oversold conditions, or crossovers of the center line.
