power hour
n.— «Going forward, we have a considerable barrier at the 1.8665 level, and a prime market environment for stop hunting activity. The most common time for stop hunting arrives at what traders commonly refer to as the “Power Hour”, the opening moments between Frankfurt and London where major FX dealing desks move a large number of hedgers orders through the market.» —“FX Universal—Forex Market Briefing” ForexTV Oct. 18, 2006.
