I am using refinitiv data's get_history() function to retrieve historical bids/asks (1 minute frequency) along with sizes/depth. I only managed to get best bid/asks but not at level 2, 3, 4 and so on (I need upto 10 levels ideally).
Please see the code snippet below. Can someone help as to what should I add more to get additional details.
Can someone also explain that why certain fields under data item browser like A_LEVEL_1, B_LEVEL_1 do not work? I tried but they do not produce anything (comes up with NaN values).
Look forward to hearing on it.
