Is there a brokerage difference or any extra charge if the OTM option expires instead of exiting it before expiry?

Is there a brokerage difference or any extra charge if the OTM option expires instead of exiting it before expiry?

With regards to selling options.

If you let your OTM Option position expire, it will expire worthless and there will be no brokerage charges, also there are no additional charges for letting your OTM position expire.

If you square-off the position before expiry, then brokerage charges will apply. You can calculate the same here.

Oh! So it’s better to let it expire then squaring off? Any advantage in exiting instead (except availability of funds)? And any impact on turnover calculation with regards to ITR?
