As Sean mentioned during the Asian session and I mentioned a few posts ago there are a lot of topside stops. When we see big moves they feed upon themselves. Option book runners like to run short gamma but get caught out when we see a big move/trend. They are then forced to continually stop loss and become their own worse enemy. So whilst the ACBs might have started this little upside move today, option players are now taking over as they are forced to cover their positions. EUR/USD last trades at 1.3748. Obviously there are barriers at 50, 75 00 etc etc.
