The main expiry on the calendar tomorrow is a $1.2 billion option at 99.50 in USD/JPY. There are slightly smaller expiries at 100 and 98.50 as well so nothing is set in stone.
Trading today has been entirely within yesterday’s range but the bigger picture points to a breakout from the long-term wedge.
Wedge breaks can be notoriously fickle so it’s probably better to wait for a break of 100.00/100.74 before gearing up.
