How accurate are OANDA Rates?
OANDA Rates are trusted by top accounting firms, international corporate and financial institutions and individuals, and are a recommended resource for tax authorities worldwide.
For major currency pairs, our rates are based on tens of thousands of different price points, collected every few seconds, 24 hours a day, 365 days a year. We collect these rates from live data suppliers, filter them to remove false prices and validate the data, and use the filtered data to compute interbank market rates.
Note: you may see this message in the Currency Converter's details section: "Estimated price based on daily US dollar rates." This message is displayed for currency pairs where relatively little data is available, and means that the exchange rate for the converted currencies was computed from cross rates with the US dollar.
