Once upon a time I was told of some neat tags one could use to download stock data from Yahoo ... and I even wrote a tutorial.
>So?
I didn't know you could also download foreign exchange rates ... if you know the symbols for the country currency.
The format goes like this:

http://quote.yahoo.com/d/quotes.csv?s=AB=X+CD=X&f=tags

>Huh?

• Start with:   http://quote.yahoo.com/d/quotes.csv?s=
• Add a sequence of:   fromto=X (separated by +)
• End with:   &f=tags

For example, try this:

http://quote.yahoo.com/d/quotes.csv?s=USDCAD=X+JPYUSD=X+GBPUSD=X+USDJPY=X+EURUSD=X&f=nl1d1t1

Note the tags I've used:
n is a name for the conversion (like:   USD to CAD) and
l1 is the conversion (like:   1.234) and
d1 is the Date (like:   3/27/2004) and
t1 is the Time (like:   3:41am).

>Yeah, but what Yahoo tags give something useful?
I have no idea. Just try all the tags in this tutorial and see which ones work.

I doubt whether Market Cap tag is meaningful
