I would like to file my 2025 tax declaration. All my profits from price appreciations, Fx trades, interest, and dividends have been recorded in Portfolio Performance. According to Hungarian regulations, profits generated in euros must be calculated based on the EUR/HUF exchange rate valid on the given date as published by the Hungarian National Bank. In addition to the default European Central Bank exchange rate in Portfolio Performance, I have also added the Hungarian National Bank’s official exchange rate as a “security-based exchange rate provider.” I have set HUF as the base currency for all brokerage accounts. How do I know that the hundreds of smaller and larger EUR revenue, expense, and withholding tax amounts are not converted using the European Central Bank exchange rate, but rather the Hungarian National Bank exchange rate I specified? Where can I set which exchange rate to use?
