Hello all,

I would like to know when the highest price value
in a given xts time series occurred but I couldn't figure out
how to do this, can anybody help?

thanks

OHLC.data <- GDAXI["2010-03-01/2010-09-10"]

# I want to know the date where the highest value occurred

max(Hi(GDAXI))
# returns only the highest value, but I would like to know the date...
