I have some sub-portfolios where stocks are in a foreign currency. I can easily get the portfolio performance either in the foreign currency or in the main one just using "exchange rate adjusted" . What I would like to get also is the average rate I purchased these same stocks . This way I would have a clear picture about the original average currency rate I paid to build a portfolio, and comparing it with current rate I can immediately feel the effect of the currencies on this portfolio.
thanks
