Currently 109.35 having found some support at 109.30 but traders are wary of large (USD 3bln) option expiries rolling off today
We may yet see the pair dragged lower toward the level but in any case keep it in mind as expiry time approaches
Update: 12.05 GMT USDJPY now falling again to 109.20
EURUSD has a decent size one at 1.2600 (EUR 881m) and EURJPY has EUR 1.8bln right here at 137.30, so we could see some action on the core pairs at prevailing prices, while AUDUSD has AUD 378m at 0.8700 and USDCAD has USD400m at 1.1200
Not always going to have impact but ignore them at your peril.. I wrote this guide a while ago to help your decision making process.
