I am having trouble running an extract using the xbbg package with the following function. It does not generate an error message but it returns an empty dataframe when a similar excel function works.
test=blp.bdp(tickers='SPX Index', flds=['INTERVAL_PERCENT_CHANGE'],calc_interval='1Q',start_date_override='2018-10-10')
It works well when I am running simple static function like this one:
blp.bdp(cusip_list, ['TICKER_AND_EXCH_CODE', 'Security_Name', 'GICS_Sector_Name'])
Date overrides for Bloomberg needs to be this format: YYYYMMDD - change 2018-10-10 to 20181010 should be good.
While xbbg is flexible with date formats, Bloomberg itself does have certain constraints.
