Trying to use chartSeries in quantmod

Quantmod abline and axis configuration
...require(rCharts)
Foa<-as.xts(read.zoo("fa.txt",col.names=c("Date","LAST"), sep="",dec=",",
format="%d/%m/%Y"))
chartSeries(Foa,theme="white",TA = c(addBBands(50,2), addBBands(100,2),
addBBands(250,2), ylim(0,4000))
)
t=chartTheme()
t$BBands$fill="#ff666633"
reChart(theme="white")
t$BBands$col=c('red','blue','green')
t$BBands$col='blue'

quantmod's addTA plotting functions
...TA <- function(from = "2010-06-01") {
getSymbols("^GSPC", from = from)
GSPC.close <- GSPC[,"GSPC.Close"]
GSPC.EMA.3 <- EMA(GSPC.close, n=3, ratio=NULL)
GSPC.EMA.10 <- EMA(GSPC.close, n=10, ratio=NULL)
chartSeries(GSPC.close, theme=chartTheme('white'), up.col="black",
dn.col="black")
addTA(GSPC.EMA.3, on = 1, col = "#0000ff")
addTA(GSPC.EMA.10, on = 1, col = "#ff0000")
# browser()
}
When I run this, GSPC.close always appears. But only GSPC.EMA10 appears on
the plot along...

The below code gives me a line chart instead of candlestick. I can't figure
out why???
chartSeries(x,
TA = NULL,
theme = chartTheme('black'),
up.col = 'white',
dn.col = 'tomato',
type = "candlesticks",
name = "EUR",
minor.ticks=FALSE)
the x object seems to have the right attributes (see below)
> class(x)
[1] "xts" "zoo"
> head(index(x))
