Methodology

How the numbers are made.

OpenRate uses cleaned P2P order book data. Extreme outlier ads, stale listings, low-liquidity ads, and low-quality merchant listings may be excluded from displayed market prices. Premiums are calculated against spot FX reference rates sourced from the European Central Bank (ECB). Currencies not covered by ECB use approximate reference rates — these are marked with spotSource: "approximate_reference" in API responses. Confidence scores, merchant scores, estimated net spreads, and execution depth estimates are model-based outputs and carry additional uncertainty — responses using them will have isEstimated: true.
