Methodology — How Our Exchange Rates Are Sourced

Currency, precious-metal and crypto prices are aggregated continuously from leading interbank liquidity providers and professional market-data terminals — the same class of feed used by trading desks. Updates stream to your browser over a live WebSocket connection, typically within a fraction of a second of the market moving.

Market prices are cross-checked against the official reference rates published by major central banks — among them the Federal Reserve (Fed), the European Central Bank (ECB), the Bank of England, the Bank of Japan and the Central Bank of the Republic of Türkiye (TCMB). Combining live trading data with official rates keeps our quotes both current and grounded.

Every price is expressed against the US dollar first, then any pair is derived consistently: A/B = (A/USD) ÷ (B/USD). This is why a cross such as EUR/TRY always agrees with EUR/USD and USD/TRY. Precious metals (gold XAU, silver XAG) are quoted per troy ounce and converted to grams, kilos and local currencies on the same basis. Crypto prices reflect the consolidated market across major venues.

Live quotes update in real time. For charts and trends we also store a daily high/open/low/close (OHLC) history per currency, kept at high numeric precision so long-term charts stay accurate. Daily bars are finalised at midnight UTC.

Our rates are indicative mid-market prices for information only. They are not transactional quotes: banks, brokers and exchange offices add their own spreads and fees, so the rate you are offered for an actual transaction will differ. We work to keep the data accurate and timely but provide it without warranty and accept no liability for decisions made on its basis.
