There are just a couple of expiries to take note of on the day, as highlighted in bold below.The first being for EUR/USD at the 1.1625 level. The expiries don't tie to any technical significance but could act as a bit of a magnet for price action in the session ahead. That as the overall market mood continues to stay more tepid and be on edge awaiting further US-Iran developments. War or not war. Deal or no deal. We are pretty much caught in limbo still since last week.As such, dollar sentiment is keeping more cagey and that's not seeing all too much conviction so far this week. So, the expiries could just lock in price action and keep things more rangebound in European morning trade at least.Then, there is one for USD/JPY at the 159.75 level. The pair came very close to testing 160.00 earlier today before backing off, as traders continue to try and test the limits of Japan's ministry of finance.I wouldn't place any weight on the expiries whatsoever as USD/JPY price action is very much a psychological game right now. It's all about how far traders want to push things before incurring the wrath of Tokyo officials. That's about it.And at some point, be it right as we cross 160.00 or a bit more than that, you can bet that Japan will want to take some action. Otherwise, it will just invalidate all of their efforts since the end of April.For more information on how to use this data, you may refer to this post here.
