After looking a the patch posted by Mike Alexander :
http://lists.gnucash.org/pipermail/gnucash-user/2009-May/029905.html

I'm starting to think that when GnuCash gets the online quote for
a currency, it does not make use of any other value than the extracted
exchange rate.

So unlike what gnc-fq-dump report, the "currency" field is not
required at all when retrieving currency prices; GnuCash already knows
what is the currency of the extracted exchange rate because it is
implied by its own request (from currency / to currency).  Right ?


---
I have the USD currency ticked to retrieve quotes online (and so is
the EUR currency as well).
I guess that GnuCash select which exchange rate to update based on the
default currency configured (here: EUR).  Still right ?

In the Price Editor, I have 2 exchange rates for currencies:
EUR-USD and USD-EUR.  When GnuCash updates the price in USD for 1 EUR,
I don't see the counter-part exchange rate when I browse the list of
EUR-USD quotes (with Source to something as "from:USD-EUR").
Does GnuCash check BOTH PriceDB (USD-EUR *and* EUR-USD) when trying to
find the appropriate exchange rate to use ?
