Add Moving Average to Chart

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.
