Average conversion rate

Hello Rafał,
sorry if it’s been already implemented, but I cannot find it easily.

I’d like to have an average conversion rate for assets I’ve bought in different currencies. The same as an average buying price. If I’m buying the same asset over a period of time, I have an account in a PLN, but the asset is in USD, it would be nice to have an overall average of what was the rate I’ve bought it.

I think when I switch displayed currency from one to another and just simply divide the numbers it gives me more or less the same thing. I’ve checked it for one asset and it was 3.673 from transactions sheets and 3.666 for the simple dividing thing.

Best,
michal
