Ok here is the explanation. Grab a cup of coffee and read on. If you have not read/noticed this, you will see intraday options movement in a new light.

Say we have two options, one 50 delta ATM options and another 30 delta OTM option. Normally for a 100 point move, the ATM option will move 50 points and the OTM option will move 30 points. But in a high volatile environment, the OTM option will also move nearly 50 points
To understand why this happens, first understand why an ATM option is 50 delta. An ATM option has the probability of 50% of expiring as ITM. The price just has to close a rupee above the strike for the CE to be ITM and vice versa for PEs
Now think of a highly volatile day like today. If someone is asked where the BNF will close for the day or expiry, no one can answer. BNF can close freakin anywhere, That makes every option of an equal probability of being ITM. So all options have a 50% probability of being ITM
Hence, when a huge volatile move starts, all OTM options behave like ATM options. This phenomenon was first observed in the Black Monday crash of 1987 at Wall Street, which also gave rise to the volatility skew/smirk
Someone asked me over DM what I will teach in the extra module of advanced greeks or it's nuances. This is just one of the things I will teach. Some things I will teach on LIVE markets. Course details here if you are interested, videos are already online :

BTW, what I have noticed is that this OTM moving like ATM happens till 25/30 delta options and not beyond.

The Dutch regulator and DNB as financial supervisor are a tough cookie to deal with. In essence they hyperregulate EU-rules into goldplated Dutch rules which go beyond what is prescribed in Europe.

All NL-customers at British banks may thus be kicked out on brexit.

If we start with the capital requirements directive, it says attracting deposits is forbidden. In article 9.

Now the translation of that rule into Dutch law is slightly expanded to not only prohibit attracting deposits, but to also prohibit, having those deposits under custody ('ter beschikking hebben').

That's not in EU law, but it is in our Dutch law.

So if you wonder how this would work out for UK banks and Payment institutions servicing Dutch customers. Have a read at the technical explanation of DNB, the financial supervisor and their summarising table.

Passive servicing of Dutch is not allowed!


Any bank or PSP in the UK that continues to serve Dutch customers (as in retail customers, professional players are excepted) can thus be subject to fines and policing under Dutch law.

Meaning we not only have Accidental American issues in payments, but also Accidental Dutchies
