Capital gains - US transactions & USD accounts
Calculating capital gains on direct transactions ignores what happens to cash in the account over the years. How does one generally go about doing this? Up to now, I've calculated cap gains as if the money were converted to CAD at buy and sell times regardless of whether any money was transferred in our out of the account. Since CAD is appreciating against USD, I should be accounting for the cash but without a transaction, how can one do this? Or can it only be done at some point in the future when the account is collapsed?
Thanks in advance.
