OHLC Plot with EMA in it

Using quantmod and TTR (for EMA, as well as many, many more technical tools):

library(quantmod)

# get some data
getSymbols("QQQQ")

barChart(QQQQ)
addEMA()

Lots of examples at:

Do like Dirk suggests and find your way to R-Sig-Finance.

Enjoy!

Hi there

I have some timeseries data which I plot in a OHLC Plot. In the same  
plot I'd like to have the EMA of this timeseries. I tried to add the  
EMA point to OHLC with lines(), but this doesn't work. Has anyone an  
idea how to handle it?

Regards, Michael Zak
