Riksbank Cross Rates: Currency Pair Rate Between Two SEK Series

riksbankswea/cross-rates

The cross rate between two Riksbank currency series over a date range, as {date, value} entries in date order, computed by the Riksbank from the two SEK fixings: for SEKEURPMI over SEKUSDPMI the value is US dollars per euro. Both series ids and both dates (YYYY-MM-DD, from earlier than to) are required. An unknown series id, and a range with no observation, answer with no content, which arrives as a PROVIDER_ERROR, not an empty list.
