EUR/USD closed last week at 1.3590 and is currently trading at 1.3640 in early interbank trade. Cable is at 1.5480, USD/JPY at 91.45 and AUD/USD at .9005. The early Monday morning market is always driven by stop-loss hunting so I suspect that there were some stops in the EUR/USD close to the market which have now been triggered.
Good luck today.
