All the stock option names indicates next month expiry is on 25th May (Sunday). For example: AARTIIND25MAY435CE However, as per NSE website and "expiry" in zerodha websocket streaming data next is 29th May (Thursday)
@sujith@rakeshr Could you please help to understand why this difference? Thanks.
The "25" in AARTIIND25MAY435CE refers to the year 2025, not the expiry date for a monthly expiry contract. You may also refer to the API instrument file.
