What a currency change affects
An account currency is the unit used to report cash and results. Changing it can alter how balances, fees and open positions appear, even when the underlying investment has not changed. A display preference and an actual currency conversion are different actions. Compare the original currency amount, conversion rate and converted amount before treating a different number as a gain or loss.
Information to confirm
Ask whether a provider permits changes to an existing account or requires a separate account. Check how open positions, unsettled payments and historical statements would be handled, and whether conversion charges apply. Save statements before any approved change. FYLU's current login preview does not provide a live currency-change service; supported account currencies and any future conversion process have not been confirmed.
