Add Moving Average to Chart

Description

Add one or more moving averages to a chart.

Usage

addSMA(n = 10, on = 1, with.col = Cl, overlay = TRUE, col = "brown")

addEMA(n = 10, wilder = FALSE, ratio=NULL, on = 1,
       with.col = Cl, overlay = TRUE, col = "blue")

addWMA(n = 10, wts=1:n, on = 1, with.col = Cl, overlay = TRUE, col = "green")

addDEMA(n = 10, on = 1, with.col = Cl, overlay = TRUE, col = "pink")

addEVWMA(n = 10, on = 1, with.col = Cl, overlay = TRUE, col = "yellow")

addZLEMA(n = 10, ratio=NULL, on = 1, with.col = Cl, overlay = TRUE, col = "red")

Arguments

n	periods to average over
wilder	logical; use wilder?
wts	a vector of weights
ratio	a smoothing/decay ratio
on	apply to which figure (see below)
with.col	using which column of data (see below)
overlay	draw as overlay
col	color of MA

Details

see the appropriate base MA functions in TTR for more details and references.
