An intuitive Bloomberg API
Below are main features. Jupyter notebook examples can be found here.
- Excel compatible inputs
- Straightforward intraday bar requests
- Subscriptions
-
Bloomberg C++ SDK version 3.12.1 or higher:
-
Visit Bloomberg API Library and download C++ Supported Release
-
In the
binfolder of downloaded zip file, copyblpapi3_32.dllandblpapi3_64.dllto BloombergBLPAPI_ROOTfolder (usuallyblp/DAPI)
-
-
Bloomberg official Python API:
pip install blpapi --index-url=https://bcms.bloomberg.com/pip/simple/numpy,pandas,ruamel.yamlandpyarrow
pip install xbbg0.7.7a2 - Custom config and etc. for reference exchange (author hceh)
0.7.6a2 - Use blp.connect for alternative Bloomberg connection (author anxl2008)
0.7.2 - Use async for live data feeds
0.7.0 - bdh preserves columns orders (both tickers and flds).
timeout argument is available for all queries - bdtick usually takes longer to respond -
can use timeout=1000 for example if keep getting empty DataFrame.
0.6.6 - Add flexibility to use reference exchange as market hour definition
(so that it's not necessary to add .yml for new tickers, provided that the exchange was defined
in /xbbg/markets/exch.yml). See example of bdib below for more details.
0.6.0 - Speed improvements and tick data availablity
0.5.0 - Rewritten library to add subscription, BEQS, simplify interface and remove dependency of pdblp
0.1.22 - Remove PyYAML dependency due to security vulnerability
0.1.17 - Add adjust argument in bdh for easier dividend / split adjustments

Above example works because 1) AU in equity ticker is mapped to EquityAustralia in
markets/assets.yml, and 2) EquityAustralia is defined in markets/exch.yml.
To add new mappings, define BBG_ROOT in sys path and add assets.yml and
exch.yml under BBG_ROOT/markets.
New in 0.6.6 - if exchange is defined in /xbbg/markets/exch.yml, can use ref to look for
relevant exchange market hours. Both ref='ES1 Index' and ref='CME' work for this example:

If BBG_ROOT is provided in os.environ, data can be saved locally.
By default, local storage is preferred than Bloomberg for all queries.
Noted that local data usage must be compliant with Bloomberg Datafeed Addendum
(full description in DAPI<GO>):
To access Bloomberg data via the API (and use that data in Microsoft Excel), your company must sign the 'Datafeed Addendum' to the Bloomberg Agreement. This legally binding contract describes the terms and conditions of your use of the data and information available via the API (the "Data"). The most fundamental requirement regarding your use of Data is that it cannot leave the local PC you use to access the BLOOMBERG PROFESSIONAL service.
