Not really issue, more just question about FILL=P and Days=A overrides

[NoahKauffman]

Hi Mathew -

I could not find in your tutorial how to override for fill=p (which is a standard override of most bbg fields, to allow for backfilling to the prev value). Days=A also is an override that allows you to force showing every actual day (i.e. not hiding weekends).

I notice the following overrides are not recognized:

con.bdh('GBPUSD Curncy', ['PX_LAST'],'20080101', '20180703',ovrds=[('FILL','P')]) con.bdh('GBPUSD Curncy', ['PX_LAST'],'20080101', '20180703',ovrds=[('DAYS','A')])

con = pdblp.BCon(debug=True, port=8194) con.start()

Maybe there is something strange about these generic overrides though? When you look under FLDS in bloomberg, they are not listed as an override, but they generically work with any field when I pull in Excel.

Let me know if i have specified the syntax incorrectly.

Best!

Hi Noah,

@NoahKauffman I assume you have resolved this issue since I have not heard back? I am going to close this. In the future for usage questions I think a more appropriate venue for asking these would be StackOverflow. There is now currently a pdblp tag which you can use there. An example is https://stackoverflow.com/questions/51383505/field-override-for-bdh-in-pdblp
