I am using this code to get price data on expired option NDXb1921A5075.U^B21:
df5 = ds.get_data(tickers="<NDXb1921A5075.U^B21>", fields=['MP'], start = '2021-01-01', end = '2021-09-18', freq= 'D' )
According to the RIC rules this option should have been expired on February 19, 2021, however the code above returns price data for up to today (see attached)
And a similar request in Eikon API returns "no data available for the requested period".
Could you please kindly consult on this ?
According to the Datastream Navigator, <NDXb1921A5075.U^B21> represents "NASDAQ 100 Index 16-July-2021 15075 Call" in datastream.
As this forum is more for programming-type queries, rather than content queries - I would recommend you raise a 'I need help understanding content within the product' ticket to the DataStream or Eikon support team via MyRefinitiv. That way a Content specialist can work closely with you and verify the problem.
