The session has seen the euro in retreat so far 17 Aug

As per the daily options post (now updated) and the EURUSD order board I warned that today's expiries would help cap rallies and so it's proved.

I'm not saying it's the only reason but certainly casting more than just a shadow with EURUSD down to 1.1742 from 1.1785, EURGBP to 0.9106 from 0.9135 ( and helping to underpin cable) and EURJPY 129.09 from 129.50

Demand at 1.1720, 0.9100 and 128.80-00 should help stem further falls but we don't rule it out with more expiries downstairs at 1.1700 as potential target.
