<html><body><div>Thanks for the response Nick. I tried your suggestions and can't seem to get this to work. I can pull in the tickers but the problem appears to be when it gets passed along to bdp where the tickers are not recognized. I pasted the tickers into excel and it starts in cell A1 and ends in A100. Here's a small sample of what it looks like </div><div><br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div><img src="blob:https%3A//www.icloud.com/f751b152-ed24-4a87-a110-bf92d9d6d447"></div><div><br>On Apr 06, 2016, at 08:17 PM, Nick White <n-e-w@qtradr.net> wrote:<br><br></div><div><blockquote type="cite"><div class="msg-quote"><div dir="ltr">Yes - this is very easy. <div><br></div><div>Do you get the error message when you run the bdp command or when you try to run the read.csv command?</div><div><br></div><div>If it's after read.csv, can you supply an extract of the header row and the first row of tickers so we can see what your file looks like?
