KST: Know Sure Thing

Description

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

Usage

KST(price, n = c(10, 15, 20, 30), ma1 = list("SMA", n=10), ma2 = ma1, ma3 = ma1, 
         ma4 = list("SMA", n=15), ma.sig = list("SMA", n=10), wts = 1:4)

Arguments

price

Price series to use.

n

A vector of the number of periods to use in the ROC calculations.

ma1

A list whose first component is a string containing the moving average function name; additional parameters may also be specified as named components. There must be a ma (not including ma.sig) for each

ma2

See ma1.

ma3

See ma1.

ma4

See ma1.

ma.sig

A list whose first component is a string containing the signal moving average function name; additional parameters may also be specified as named components.

wts

A vector the same length as n, of the weight for each period (need not sum to one).

Value

• A vector containing the Know Sure Thing values.

Details

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.).
