quantmod: how to add custom timeseries (addTA?)
Michael, I'll have to leave that question to Jeff Ryan, the package author. You can avoid printing a legend for the lowest low by using the TA= arg in chartSeries: chartSeries(YHOO, TA="addTA(min55,on=1)") Best, Josh -- http://blog.fosstrading.com/

Jopp! The argument on = 1 from addTA() helped me totally. How can I prevent printing a legend at all from the addTA()? legend=FALSE doensn't work. Thank you, Michael On 08.10.2008, at 15:02, Josh Ulrich wrote:
Hi Michael,
Try this:
require(quantmod)
require(TTR)
getSymbols("YHOO")
chartSeries(YHOO)
min55 <- runMin(YHOO$YHOO.Low,55)
addTA(min55,on=1)
Best,
Josh
