Why the 2nd get_history is failed

tony.cheng

Hello. I have a python program (using refinitiv.data library) that will obtain the refinitiv data twice:
1st part. get_data for [ 'trd_status', 'CF_DATE', 'TR.ACCUMULATEDVOLUME(SDate=0,EDate=0,Frq=D)', 'TR.ACCUMULATEDOFFBOOKVOLUME(SDate=0,EDate=0,Frq=D)' ] for a list of securities, which works fine.

split_rq3 = rd.get_data(

universe = instruments,

fields = [

'trd_status', 'CF_DATE', 'TR.ACCUMULATEDVOLUME(SDate=0,EDate=0,Frq=D)', 'TR.ACCUMULATEDOFFBOOKVOLUME(SDate=0,EDate=0,Frq=D)'

], )

For 2nd part. get_history for [ 'TR.ACCUMULATEDVOLUME(SDate=0,EDate=-15,Frq=D)', 'TR.ACCUMULATEDVOLUME(SDate=0,EDate=-15,Frq=D).date', 'TR.HIGHPRICE(SDate=0,EDate=-15,Frq=D)', 'TR.ACCUMULATEDOFFBOOKVOLUME(SDate=0,EDate=-15,Frq=D)' ] for 4 securities.

split_rq0 = rd.get_history(

universe =instruments,

fields = [

'TR.ACCUMULATEDVOLUME(SDate=0,EDate=-15,Frq=D)',

'TR.ACCUMULATEDVOLUME(SDate=0,EDate=-15,Frq=D).date',

'TR.HIGHPRICE(SDate=0,EDate=-15,Frq=D)',

'TR.ACCUMULATEDOFFBOOKVOLUME(SDate=0,EDate=-15,Frq=D)'

],)

The program get stuck in the 2nd part (no response for more than 10 minutes) and needs to disconnect the workspace in order to stop the program. May I know if it's connection issue or it's library version issue? It's my library version:
refinitiv-data 1.6.1

Thank you for reaching out to us.

You may need to enble the debug log in the RD library to verify what the problem is. You can run the following code to enable the debug log.

config = rd.get_config()
config.set_param("logs.transports.file.enabled", True)
config.set_param("logs.transports.file.name", "refinitiv-data-lib.log")
config.set_param("logs.level", "debug")
rd.open_session()

Then, the refinitiv-data-lib.log will be created. From the log file, we can check if the server sent the response message back to the RD library.
