    Not reproduced. Seems like IQFeed client not running or has different lookup port settings. Please check IQFeed client and test if below is working:

    ## Generic parameters 
    library(QuantTools) 
    from = '2016-01-01'
    to = '2016-06-01'
    symbol = 'SPY'
    
    ## Request data 
    get_iqfeed_data(symbol, from, to)

    Have you installed iqfeed client on your system? have you changed its default settings? Does Iqfeed watchquote work?

    I tried to download and install DOWNLOAD IQFEED CLIENT, but the account seems chargable to register... by the way, will the QuantTools::Order() function will place order in real account via API ?

    Yes, IQFeed is not a free service. At the moment QuantTools works only in simulation mode.

    What if I try to use Finam data instead of IQfeed? Can Quanttools store the data with google or Yahoo data source? I am using a trial version of IQFeed. And when i tried to code with IQfeed settings, the code didnt seem to run as the IQFeed software was really buggy.

    Commenting here as I got the same error which you have marked invalid. @quanttools
