I would like to cross-check exchange rate used for a transaction. Exchange rate used for the transaction is based on mid-reuters (the average between reuters bid and ask rates) plus a margin.
Is there any site to obtain historical mid-reuters exchange rate for a pair of currencies at a specific date and time? The shorter the period, the better. Preferably 1 minute low/high quotes, but longer periods of up to 1 hour may also work. Chart is not needed, but is an acceptable alternative.
