See the technical charts, the strategy advocated on 27th May, 1 week from there - ITM shorts would've fetched you sure shot yields by now.

Please refer below for the strategy advised on the same day of analysis:

Well, 1 week from then the underlying spot rates have been well above (1%) ITM strikes (i.e 78.5376).

Has it not remained well above ITM strikes?

Had you used the European style options, then writers could be rest assured as no fear for exercising these options.

The spot rate on expiry date is 79.209 that mean the shorts have expired worthless.

Now is the time for the functionality of long options with 17 more days left for expiry (because 1m expiry on longs) and the pair has begun to tumble from last two days.

Time for the functionality of long puts (2 lots with 1m expiries). As expected the RBA to remain on hold for some time, the cash rates have been unchanged at 1.75%.

Technically, both leading as well as lagging oscillators have been confirming major bear trend continuation.

Thus, we advise increasing the proportion in long puts as the potential slumps on cards. ATM puts are more likely to expire in the money as IVs are on higher side on both 1w and 2w tenors.
