Comment on STT Trap - Options Expiry - NSE BSE MCX-SX

Hi Venu,

You did not understand my question. I knew that STT is only while selling options. My question is at what price will the exchange settle the buy trade if I don’t square off. If the exchange does that at theoretical price based on the closing price of the underlying index, the writer would rather gain by squaring off the order himself rather than leaving it to the exchange.

Thanks
