Free delayed quotes and a plethora of other financial data

If you are looking to import quotes into an excel spreadsheet, I haven't found anything else as convenient or extensive.  It can take you a while to get up to speed on the data available but it is worth it.   The range of data available, for free, is mind boggling.

note, the last trade quote is l1 (lowercase 'L' then the number '1')  (that drove me nuts for a while)

here's how it looks in my spreadsheet  =RCHGetYahooQuotes(+Z2,"l1")

This is only one small segment of the data,  The full excel list of all the data points available can be found here:  http://ogres-crypt.com/SMF/Elements/ and it is a truly phenominal amount of data.  Yes, some of it is repetitive but if you are looking for data on a security, start here.  

There's also an active message board if you have any questions on implementation:

Of course you can get one cell to refer to another, so one can populate quite a bit of data in a spreadsheet by just entering the symbol.  Best part is it's all free.  

I use the plug-in almost daily and would honestly be lost without it.  I suggest you give it a try as well.
