Official exchange rate for CGT

[Teixe]

I am calculating my CGT, Which official exchange rate should I use?. I found these two:

http://www.hmrc.gov.uk/exrate/exchangerates-1011.p...


http://customs.hmrc.gov.uk/channelsPortalWebApp/ch...

I suppose is the former as the latter applies to customs ?
If so, it means that for any trade before the 31/12/10 I should use only one conversion rate.
My CGT is purely on shares if that makes any difference.

Thanks

If my memory serves me correctly as it is a while since I actually did a CGT calc, you use the ex rate of the date of purchase for the purchase price and the exchange rate at the date of sale for the sale price. Use OANDA to get these spot rates.
