The final settlement day for Index Options is the business day immediately following the expiry day, which is the business day preceding the last business day of the contract month. Meanwhile, the final settlement day of One-Day Rolling Currency Futures Contracts is the second FX Business Day after the day on which open positions are closed. If the day is a bank holiday either in New York or in its respective countries, then settlement shall be on the next FX Business Day which is not a bank holiday in both New York and its respective countries.
