Rate history from Coinfuty market data: hourly closes for the 24H and 7D views, daily closes beyond that. The GBP leg is held at today's reference rate across the whole series — daily FX history is not part of this dataset. The live rate at the top comes from our own price sync, so the last point can differ slightly.
What you actually receive, exchange by exchange
