They are for EUR/USD with the standout being a large chunk at the 1.1550 level, but also big ones at the 1.1560 level. Together, they make the 1.1550-60 region a key expiry zone for today rather than viewing them as separate strikes in isolation.

The expiries hold near the 100-day moving average, seen at 1.1554 currently, so they also tie to some technical significance on the day.

With the dollar holding firmer to start the week amid more hawkish Fed expectations and EUR/USD price action resting below that key level, the impact of the expiries can be viewed as more of a ceiling to any upside price extensions.

That unless we get any macro catalysts to change the broader market sentiment ahead of the Fed tomorrow, which is unlikely.

As such, the expiries may just keep any upside price extensions in check and potentially keep price movements a bit more sticky if we see price action hang around that zone heading towards expiry.

Besides that, there are no similarly compelling combinations of large size and close proximity expiries for other dollar pairs for the day.
