Hello @eirik10

I am not the DataStream and content expert, but the DataStream symbol and field names are not the same as on the Eikon/Workspace.

The Close Price field should be "P".

You need to encapsulate the RIC code with "<>" to request data from Datastream (like "<TSLA.O>").

I highly recommend you find the Datastream symbol/Mnemonic and fields from the Datastream website (you can log in with your Datastream credentials). I found some of your requested symbols in the Datastream website.

• XLE -> U:XLE
• CLc1 -> NCLC.01 (or <CLc1>)
• ESc1 -> ISMC.01 (or <ESc1>)
• TSLA.O -> <TSLA.O>

df = ds.get_data( tickers = ",".join([ 'U:XLE', 'NCLC.01','ISMC.01',  '<TSLA.O>' ]), fields = ['P'] )
