There's some large size option expiries rolling off today at 15.00 GMT
I highlighted them in my usual post earlier but here are the closest ones again:
EURUSD 1.0800 (EUR 2.3bln) 1.0900 (1.13bln) 1.1000 (1.9bln)
AUDUSD 0.6875 (AUD 727m) 0.6900 (317m)
We've seen rallies in EURUSD contained as indeed we have the AUDUSD falls and it's not coincidence that these expiries are having an impact.
Don't forget that vanilla options are live until expiry so will continue to cast a shadow even if breached, which some have been already.
