Anyone know why the Euro dropped a quarter of a cent at 4:45 AM PST, 45 minutes before NFP? Volume was pretty much flat for a few minutes before that time, and then 6k cars were traded within half a minute, which to me looks like some kind of news release. But there is nothing at that time on any Forex calendar I can find, and I don't see any key price point that was broken and could explain the move. Any theory on why that drop happened?
