KST - Know Sure Thing

Printer-friendly versionPDF version
The Know Sure Thing (KST) Indicator is an oscillator developed by Martin J. Pring that gives bullish and bearish momentum signals. The difference between this indicator and other oscillators is that it takes into consideration four time periods instead of only one. Each time period is smoothed using a moving average. Also, each time period is weighted differently depending on length, so a longer time period would have greater weight. Because of the consideration of the various time periods, the KST is able to react more quickly to price moves.

Watch for bullish and bearish momentum signals in the KST indicator. When the KST turns upward, this is a bullish signal, and when the KST turns down, this is a bearish signal. More confirmation is given when the trigger line crosses the KST line as a result of the change in direction.

There are two lines: the trigger line and the KST line. The KST line is a result of the four moving averages smoothed as well as the Rate of Change or ROC. The trigger line is a moving average of the KST.

Buy/Sell Signals

A buy signal occurs when the KST line is below the 0 line and crosses from below the trigger line to above the trigger line. A sell signal occurs when the KST line above the 0 line and crosses from above the trigger line to below the trigger line.
