Hi @Maximilian_Lu ,
Using https://developers.lseg.com/en/video-catalog/data-item-browser tool to check available fields of LCOc1, I cannot find the field name you're using.
Could you please trying to use the https://developers.lseg.com/en/video-catalog/data-item-browser to find the proper field to be used? You could also raise a content query via https://myaccount.lseg.com/content/mytr/en/helpandsupport.html and the helpdesk is going to contact you to assist on this.
Do you know how to extract time series for the LCOc1
A field named CF_CLOSE is not avaiable in get_history data of this RIC. Available fields can be found by calling get_history without inputting the fields list
ld.get_history("LCOc1")
Here's the available field of get_history('LCOc1')
'TRDPRC_1', 'OPEN_PRC', 'HIGH_1', 'LOW_1', 'ACVOL_UNS', 'BID', 'ASK', 'OPINT_1', 'TOTCNTRVOL', 'TOTCNTROI', 'SETTLE', 'MID_PRICE', 'VWAP', 'EXERCISED', 'IRGVOL', 'EFP_VOL', 'ORDBK_VOL', 'NUM_MOVES', 'EXPIR_DATE', 'CRT_MNTH', 'SETL_PCHNG', 'SETL_NCHNG'
To check which field can be used instead of CF_CLOSE, you can raise a content query via https://community.developers.refinitiv.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fmyaccount.lseg.com%2Fcontent%2Fmytr%2Fen%2Fhelpandsupport.html and the helpdesk is going to contact you to assist on this.
