How can I start Bloomberg API in python?

Question

I managed to install blpapi in my python. However, there is error Exception: failed to start session My simple code is as follows.

import blpapi
import pandas as pd
import tia.bbg.datamgr as dm

mgr = dm.BbgDataManager()
sids = mgr['MSFT US EQUITY', 'IBM US EQUITY', 'CSCO US EQUITY']
df = sids.get_historical('PX_LAST', '1/1/2014', '11/12/2014')

What Can I do with this? Can you help?

Answer 1

Don’t need to worry about connections if you use xbbg:

from xbbg import blp

blp.bdh(
    ['MSFT US Equity', 'IBM US Equity', 'CSCO US Equity'],
    'Px_Last', '1/1/2014', '11/12/2014'
)

Output:

ticker     MSFT US Equity IBM US Equity CSCO US Equity
field             Px_Last       Px_Last        Px_Last
date
