How the numbers are made

  • Source: European Central Bank, euro foreign exchange reference rates. Reference rates: the ECB sets them around 14:10 CET on every TARGET working day, by a concertation between central banks, and publishes them around 16:00 CET. They are published “for information purposes only”: they are not the price of any trade, and the ECB strongly discourages using them for transactions.
  • Cross rate: AUD/USD is computed from two ECB rates of the same day, US dollars per euro divided by Australian dollars per euro. It is not a market quote of AUD/USD and can differ slightly from the rates banks and exchanges showed at that moment.
  • Our calculations: cross rates, changes, averages, highs and lows and the candles are calculated by BigCapital from the ECB's published rates (the ECB's terms ask that such calculations be stated).
  • The line: for periods over three years, the last rate of each week (plus the highest and the lowest rate of the period); for shorter periods, every rate.
  • Candles and bars: built from the daily rates, one per week, month, quarter or year, whichever fits the chart's width (the caption says which). Each opens at the last rate before its period; its high and low are the highest and the lowest rate in it, and it closes at its last rate. Each rate is one number a day, so these are not intraday highs and lows.
  • Changes: the latest rate against the rate in effect on the same date a week, months or years earlier (the last rate on or before that date).
  • Years: the first and the last rate of each calendar year, the highest and the lowest with their dates, and the average of all its rates; the change is the last rate against the last rate of the year before.
  • Largest moves: from one working day's rate to the next.
  • No inflation adjustment: a real exchange rate needs the price levels of both countries, so these pages show the rates as published.
  • Updates: every night. The ECB publishes on working days around 16:00 CET; the Bank of Russia sets the ruble rate on its working days for the next day.
  • Not investment advice. Past exchange rates do not tell where a currency goes next.
