When i was trying to place on order for banknifty for 16 jun expiry it is giving me errror as InputException: The instrument you are placing an order for has either expired or does not exist.
I tried to look for BANKNIFTY16JUN35000CE in kite.instruments() it is not available there too

But now ,Bracket orders have been discontinued.
