Binary options on EUR / USD
EUR/USD is the busiest FX pair. Most of the move comes in London and New York. The card shows 88%. At night this day ticker stops: those hours use EUR/USD OTC.
The euro is the shared currency of the euro area. It started as book money in 1999, and notes and coins followed in 2002. The European Central Bank issues it, so the dollar rate sets the ECB beside the Federal Reserve. It is the most traded currency pair.
