in financial technical analysis, the know sure thing (KST) oscillator is a complex, smoothed price velocity indicator developed by Martin J. Pring.
A rate of change (ROC) indicator is the foundation of KST indicator. KST indicator is useful to identify major stock market cycle junctures because its formula is weighed to be more greatly influenced by the longer and more dominant time spans, in order to better reflect the primary swings of stock market cycle. The concept behind the oscillator is that price trends are determined by the interaction of many different time cycles and that important trend reversals take place when a number of price trends are simultaneously changing direction.
