Why choose OANDA's rates?

OANDA Rates are accurate and reliable. We have been in the business of providing Rates data for 20 years, and our rates are trusted by tax authorities, auditing firms, thousands of companies and millions of individuals globally. There are over 190 currencies and commodities, with over 38,000 pairs available. Our historical rates date back to 1990, making us the world's most comprehensive FX data provider.

And of course, it's easy to use/implement - our automated FX data feed plugs OANDA® Rates directly into your ERP or proprietary system.

How are OANDA's rates calculated?

The exchange rates provided by OANDA are averages for the global foreign exchange market gathered from frequently updated sources, including our OANDA fxTrade currency trading platform, leading market data vendors, and contributing financial institutions. Most of our rates are based on tens of thousands of different price points, collected every tick, every second, 24 hours a day, 365 days a year. Our state of art technology then validates rates and detects/filters anomalies using algorithms, and calculates the average of all the collected data over a 24-hour period to make it available to our customers.

Do you have any partners who can help us integrate OANDA's rates data into our ERP system?

Yes. To help our customers integrate our FX rates seamlessly, OANDA partners with many of the major ERP systems including Oracle, NetSuite, Microsoft Dynamics and SAP. For more information, please contact our FX integration specialists at

Why are OANDA's rates different from other sources?

OANDA quotes are derived from frequently updated sources, including our OANDA fxTrade currency trading platform, leading market data vendors, and contributing financial institutions, which may or may not reflect the same prices of other companies as they can have different sources. FX is an Over-the-Counter (OTC) market, which means that OTC contracts are not executed and cleared on a central exchange where you may find the same prices on stocks, options and futures. The source and quality of your FX data therefore becomes critical to your business.

OANDA offers actually traded currency value data to our clients and recognized globally as the standard for accurate data provider.

Where can we find more details on the OANDA API or developer’s page?

You can find the API documentation here.

What time do you publish the latest rates?

To service our customers all across the world, we publish our rates every day at 2:00AM UTC. The values represent the average of the most recently completed 24-hour period ending on the same day.

Prices for the currencies of some emerging market countries may be published less frequently.

We are subscribed to the OANDA Basic Plan. How do I check the number of quotes remaining?

You can check your API usage anytime at your convenience on our query builder page. Please have your API Key information ready.

We need the average value of a specific time-frame, not the daily average. How can we do this using the OANDA API?

You can specify a timeframe by replacing the "date=YYYY-MM-DD" part of the query with "start=YYYY-MM-DD&end=YYYY-MM-DD" to get the average of your choice (i.e. weekly, monthly, yearly)
