It's been a tight range for USJPY in this session so far.
Earlier I highlighted the decent size expiries at 113.00 rolling off at 15.00 GMT today and while they're not the whole reason I am confident that they playing their part in keeping the pair pinned around the price.
Keep the info in mind and more so as we near expiry time.
Currently 113.05.
