AUDUSD has a large option expiry today 18 May 2016
As per my earlier daily post we have AUD 944m rolling off at 0.7300 and judging by the price action I'd say someone has a decent interest to keep the pair capped below there until expiry at 14.00 GMT.
Currently 0.7280 we've seen a couple of rally attempts struggle to even get over 0.7290 so it seems the offers are in place ahead of 0.7300 as one would expect.
Corporate demand between 0.7250-60 have held the drop so far so expect further tight ranging for the moment.
