I bought 10 lots of USDINR strike price of 70 Rs at a premium of 0.5,

So my total premium would be 500 Rs + Taxes.

Now consider expiry is tomorrow and LTP for USDINR Nov 70 is 0.8,

which means, if i sell now i’ll get 800 Rs - taxes.

What happens if i let the options expire and the expired prices is 1 rs ??

Thanks in advance.

Regards

Prem
