Confusion regarding STT on expiry Days

[Aey_K]

I read the dreadful stories of stt traps from past but it has been fixed since 1 sept 2019 as per the post linked below. But just to be safe I want to get an accurate understanding of stt on expired options. Example: I buy 800 (32 lots) Bnf 38000 CE options at market price 10 rupees and they expire at market price 20 rupees. The option expired 20 points in the money @ 38020. What will be my tax obligation.

Addressed here:

@ShubhS9

If your long option position expires ITM, the exchange charges STT at 0.125% on the intrinsic value. There won’t be any additional STT if it is a short position, as STT is already paid when you sell the option.

Brokerage will be applicable if the position expires ITM. If it is OTM, it will expire worthless and no brokerage will be applicable.

So the stt shall be applicable to 20 points? so in the example I have given the STT will be 20 rupees? .(20*800)*0.125%

This is correct
