I'm french, and I bought some stocks in Paris and New York Stock Exchanges. I'm trying to use an online portfolio tracking tool like Google Finance, but the final gain value is incorrect because of currency fluctuation.
Let take a simple example : I have a share of a company X which I bought $100 with a €/$ rate of 0.87, so I payed 87€. Now, the share is worth $102 and the €/$ rate is now 0.85. So the current value is 102 * 0.85 = 86.70€, and i'm loosing 0.30€.
But Google finance is not taking the share buying conversion rate, so it calculate like this :
gain = ($102 - $100) * 0.85 = +1.7€
but the good calculation should be :
gain = ($102 * 0.85) - ($100 * 0.87) = -0.3€
Did I miss anything, or is it impossible to do what I want in Google Finance ? And if it is not possible do you know any other website or Android app that allow conversion rate input ?
Thanks in advance for your help.
