British Pound / US Dollar (GBPUSD) market data
GBPUSD is the major pair for British Pound against US Dollar.
About British Pound / US Dollar (GBPUSD)
GBPUSD is the value of the British pound in US dollars, quoted as dollars per one pound. It is among the most liquid currency pairs and trades continuously through the interbank week.
SiftingIO merges GBPUSD from several independent sources into a single rate. The live quote carries bid and ask with sizes, the mid, a basis-point spread, the venue count, the 24-hour change, and a millisecond timestamp, available as a REST snapshot or a WebSocket stream.
Bars are served over REST at one-minute through daily resolution in UTC. As with all spot FX, the bar volume field is always zero, since there is no central tape for cash currencies, though the bars still carry open, high, low, and close. The history you can reach depends on your plan tier, from a recent free window to the full archive above, per the pricing page.
Higher tiers refresh the rate more often, from one to ten updates per second, and the median age of a published rate stays under 100 milliseconds as a freshness measure. Each GBPUSD figure is a volume and reputation weighted median across venues with source, ingest, and publish timestamps and a quality flag.
