Total book cost and currency conversion

[Fr4ncis]

Hi,

I am fairly new to the platform and I have been placing some orders, mainly for US stocks and some UK ones. Account is UK, the total book cost is in GBP. The only way to reconcile the total book cost with the money I actually paid for the stocks, is by using the current GBP/USD conversion and apply that to the book cost for each US stock, therefore the sum of GBP and USD position is calculated with the current conversion, which does not make much sense to me, as if the currency fluctuates, it makes the overall profit change. Do you have any recommendation on how to handle this? I thought about editing the books, but the currency fluctuations would still affect the totals and profit. Are there better tools to keep track of the "real" profit?

Best Regards
