Fast Stochastic

fast_stochastic() is a generic S3 function that preserves the input class: data.frame in, data.frame out; matrix in, matrix out.

Handling of -values

Leading NAs are always produced for the initial lookback period where insufficient data is available. If the input itself contains NAs they are passed through to the underlying C routine, which can cause the entire output to be filled with NAs. Set na.ignore = TRUE to strip NAs before calculation and re-insert them at their original positions in the output.

Usage

fast_stochastic(
  x,
  cols,
  fastk = 5,
  fastd = SMA(n = 10),
  na.ignore = FALSE,
  ...
)

Arguments

x

An OHLC-V series coercible to data.frame.

cols

(formula). An optional 3-variable formula selecting columns from x via model.frame. Defaults to ~high + low + close.

fastk

(integer). Period for the fast-k line.

fastd

(list). Period and Moving Average (MA) type for the fast-d line. SMA by default.

na.ignore

(logical). A logical of length 1. FALSE by default. If TRUE, NAs in the input are stripped before calculation and re-inserted at their original positions in the output.

...

Additional parameters passed into model.frame

Value

An object of same class and length of x:

FastK

double

FastD

double
