KST | R Documentation |
The Know Sure Thing (KST) is a smooth, summed, rate of change indicator. Developed by Martin Pring.

n = c(10, 10, 10, 15),
nROC = c(10, 15, 20, 30),
nSig = 9,

)
price |
Price series that is coercible to xts or matrix. |
n |
A vector of the number of periods to use in the MA calculations. |
nROC |
A vector of the number of periods to use in the ROC calculations. |
nSig |
The number of periods to use for the KST signal line. |
maType |

wts |
A vector the same length as |

Other arguments to be passed to the |
For each day (week, month, etc.), the KST calculates the ROC over several periods. Those ROCs are smoothed using the given moving averages, then multiplied by their respective weighting values. The resulting values are summed for each day (month, week, etc.).
A object of the same class as price
or a vector (if
try.xts
fails) containing the Know Sure Thing values.
The KST indicates bullish/bearish momentum as it crosses above/below its moving average. Because the KST tends to lead price action, look for trend confirmation in the price.
The default arguments are for the daily KST. There is also the Long-Term
KST, with arguments: n=c(9, 12, 18, 24)
- where the periods are
months, not days - and the moving average periods are 6, 6, 6, and 9 months,
respectively.
