The trading_volume() is a generic S3 function that builds upon 'type-safe'-esque workflows limited to classes in in base R, and the package-wide dependencies. Ie. class in, class out. Each method is a soft wrapper of model.frame and therefore the OHLC-V series must be coercible to a data.frame.

Handling of -values

trading_volume() iterates over valid values, and returns NA for the remaing part of series.

Usage

trading_volume(x, cols, ma = list(SMA(n = 7), SMA(n = 15)), ...)

Arguments

x

An OHLC-V series that is coercible to data.frame.

cols

(formula). An optional 3 variable formula passed into model.frame. Internally uses ~volume + open + close by default.

ma

A list of MA specifications.

...

Additional parameters passed into model.frame

Value

An object of same class and length of x:

VOLUME

double

SMA7

double

SMA15

double
