Comment on STT Trap - Options Expiry - NSE BSE MCX-SX
If you have sold options, you would have already paid STT and don’t have to worry about paying a higher STT and it doesn’t matter if the option is in the money or not, you can let it expire.
But if you have bought options and it is expiring in the money, then it makes sense to sell it in the market rather than holding it, because then you pay higher STT.
Cheers,
