Developed by Martin Pring, Know Sure Thing (KST) is a momentum oscillator based on the smoothed rate-of-change for four different timeframes.
KST fluctuates above/below the zero line. At its most basic, momentum favors the bulls when KST is positive and the bears when KST is negative.
Even though there are many different signals possible with KST, the basic centerline and signal line crossovers are usually the most robust. Unlike RSI and the Stochastic Oscillator, KST does not have upper or lower limits. This makes it relatively ill-suited for overbought and oversold signals.
I added the possibility to add on the chart a 2nd timeframe for confirmation.
