There are a couple of big expiries to take note of on the day, as highlighted in bold below.The first ones are for EUR/USD and they are layered between 1.1350 through to 1.1410, with also some other larger ones extending beyond that range. The expiries don't tie much to any technical significance but could offer a bit of attraction in keeping price action more sticky in the session ahead.That being said, there's the 100-hour moving average at 1.1386 currently. And that may offer some near-term limitations to the upside for the currency pair, with the expiries above acting as an added defensive layer. In particular, the ones at 1.1400-10 may offer some interest in acting as a ceiling for any price extensions in European trading.All in all, the dollar and broader risk mood will also still act as key drivers of trading sentiment. So with a more defensive risk mood seen for now, that could lend some downside pressure to EUR/USD in case the risk selloff starts to permeate to other areas of the market.If so, the expiries to the downside will be of more interest in locking price action from falling too much.Then, there's one for USD/JPY at the 161.50 level. But as mentioned before, the currency pair is largely tied to intervention risks at the moment. So, there won't be any impact in the expiries to really sway price action as traders are keeping caution and jumpy over potential action by Tokyo.For more information on how to use this data, you may refer to this post here.
