[GNC] Australian Foreign Investments Taxation

[Ben Stanley]

Hello Gnucash people,

This question may be more suited to Gnucash developers, but lets try it 
here first.

I need to perform a tax calculation in accordance with instructions from 
the Australian Taxation Office. All foreign income, deductions and 
foreign tax paid must be converted to Australian Dollars for tax purposes.

The conversion used must correspond to the transaction date.

In Gnucash, it would appear that the price editor could be used to enter 
the necessary conversion data, if it were easy to see all of the dates 
where conversions are required. However, this is tedious.

Far better would be to use Finance::Quote to fetch the necessary 
conversion data for the dates it is required for. However, it seems that 
Finance::Quote is only capable of fetching "recent" data. (The 
documentation that I looked at seemed to be very old.)

http://finance-quote.sourceforge.net/documentation.html

What is needed is the ability to pass a date, or a range of dates, and 
request Finance::Quote to fetch prices for that date or date interval. 
This would make Finance::Quote far more useful than just fetching the 
most recent price data.

Is there some feature in Gnucash that I have missed that would allow me 
to generate a report, with dividends and Capital Gains converted from 
USD -> AUD using the currency conversion as at the transaction dates?

Thanks,
Ben Stanley.
