Oanda and U.S. Forex Foreign Exchange Services offer historical exchange-rate data for users to compare information related to multiple currencies, according to each organization's website. Customize information such as the time period and number of currencies through each service to compare rates.
The Oanda website offers several features, including a currency converter and currency tools, to compare exchange rates. Select a specific date period, which ranges from seven days to five years. You can also choose a custom date range. Modify the price, value and frequency data accordingly. Compare the currency rates on either a graph or table, notes the Oanda website. View live exchange rates to see data for that particular instance, if necessary.
The U.S. Forex Foreign Exchange Services also offers an exchange rate tool in addition to spot exchange rates for a variety of currencies, notes the organization website. Enter each relevant currency, a rounding point, a fixed period or a custom period to view the associated exchange-rate data. A table then populates all of the information, including date and associated exchange rates for the relevant currencies. In addition, this website provides Interbank rate snapshots, seasonal exchange rates, monthly return percentages and monthly average rates, as well.
