Know Sure Thing
Know Sure Thing was developed by Martin J. Pring in the 1990s. The KST uses four rate of change values to determine the trend of the market. The user may change the input (close), methods (SMA, EMA) and multiple period lengths. This indicator’s definition is further expressed in the condensed code given in the calculation below.
How To Trade Using Know Sure Thing
If the KST crosses above the SIGNAL line a buy signal will be generated. Conversely, if the KST crosses below the SIGNAL line a sell signal will be given.
