Also, the compulsory exercise is now gone. So worst that can happen to you is that if you have an option whose intrinsic value is less than STT (.125% of underlying) on expiry, you can choose not to exercise it. So in that case you make no money.

It was bad in old days, when you could make 2 points as intrinsic value and pay 13 as STT because of compulsory exercise

Thanks… :slight_smile:
What I understood; STT trap is basically for option buyers when the option expires ITM. To avoid STT trap option buyers are suggested to close their position before expiry. (Though they will lose a part of their premium). But my question is; how will I (assuming I have an option which is ITM) find a buyer because there will be no buyer on expiry?
Option sellers are out of this, doesn’t matter whether option expires ITM, ATM or OTM. Am I right?

In the last part of the webinar and the post, the buyer trapped with ITM has to potentially pay 900 plus rupees as STT in most options. If she exercises, she will end up paying STT in most cases. The better outcome is to square it off with someone at a slightly more than STT affected price, which is slightly less than theoretical price.

Any one who had sold options with net short position will buy this ITM option from you, squaring off their short positions. They do not have to pay STT because they only become 0 from net short at expiry. Any such person will happily take up this deal because they get a better price to square off on their losing ITM short positions.

So if you are a seller originally, and the option went ITM, and now you are looking to buy back and square off, you will always find someone, who has an ITM option he originally bought. He will give you a better deal to avoid STT.

If you are a buyer trapped with ITM, you will always find someone who has a net short, who wants to square off with you and exploit this.

Hope that clarifies.

let’s assume I sold 100 shares of Nifty 10,000 @premium 1 rs and it goes to 10,051 on expiry.
so to close my position I’ve to buy it by paying 51 rs to someone on another side (Through exchange).
But in this person on another side has to pay (100511000.125%) = 1256 as TAX on the profit 5100.
so he will get only 3844 (5100-1256)
So we will do dutch to settle this @ 6.28 premium {(1256/2)/100}. ie I’ll buy back Nifty 10,000 @ premium 43.72 (50-6.28) and that person will get 4372 (100*43.72) instead of 3844.
Both will have an advantage of 628 rs :slight_smile:
Am I right?
