OTM options when trading halted on expiry day

What happens to OTM options when trading is halted for remainder of day (For eg, 20% uptick or downtick)? OTM option strike is beyond this final price.

otm expire worthless , compared to last closed price I guess…

Are you sure? I can not find any literature from NSE or BSE.

@nithin @siva could you clarify this?

Have the same doubt. Maybe @Karthik can help.

I think on expiry ITM are cash/delivery based settled and OTM are reduced to 0. That’s it

If it’s OTM, it will be worthless.

Thank you Siva for clarification.

@siva In the case where Nifty loses more than 20% and trading is halted for the day. Will all the products listed in NSE be halted or only Nifty underlyings?

Everything will be halted, complete market.
