Pairs like the EUR/USD have been trapped in between big option interest over the last 2 weeks but this interest will evaporate after 2.15 pm this afternoon. The established trading range has been 1.3700/1.4170 but both of these levels are likely to be a magnet for macro stop-loss strategies so don’t expect them to hold if the FOMC announce something well beyond market expectations in either direction. 200 or 300 pip moves are certainly feasible so be careful out there and keep risk at a manageable level. You probably won’t get rich today but you might get poor!!
