Bloomberg data toolkit for humans

## Requirements

- Bloomberg Open API

```
pip install --index-url=https://bloomberg.bintray.com/pip/simple blpapi
```

- Bloomberg C++ SDK version 3.12.1 or higher
    - https://www.bloomberg.com/professional/support/api-library/
    - Downlaod C++ Experimental Release
    - Copy `blpapi3_32.dll` and `blpapi3_64.dll` under `bin` 
    folder to Bloomberg installation folder `blp/DAPI` 
- [pdbdp](https://github.com/matthewgilbert/pdblp) - pandas wrapper for Bloomberg Open API
- numpy, pandas and pyarrow

## Installation

```
pip install xbbg
```

## Tutorial

Creation of connection `create_connection()` is not necessary.
Quries will create new connections if there's no live connections on the backend.
Since each initiation of connection takes time, we can manually connect
before we want to do multiple queries - just like examples below.

```python
In[1]: from xbbg import blp

In[2]: blp.create_connection()
```

```pydocstring
Out[2]: (<pdblp.pdblp.BCon at 0x1c35cd0e898>, True)
```

- ``BDP`` example:

```python
In[3]: blp.bdp(tickers='NVDA US Equity', flds=['Security_Name', 'GICS_Sector_Name'])
```

```pydocstring
Out[3]:
           ticker             field                   value
0  NVDA US Equity     Security_Name             NVIDIA Corp
1  NVDA US Equity  GICS_Sector_Name  Information Technology
```

- ``BDH`` example:

```python
In[4]: blp.bdh(
  ...:     tickers='SPX Index', flds=['High', 'Low', 'Last_Price'],
  ...:     start_date='2018-10-10', end_date='2018-10-20',
  ...: )
```

```pydocstring
Out[4]:
ticker     SPX Index
field           High      Low Last_Price
date
2018-10-10  2,874.02 2,784.86   2,785.68
2018-10-11  2,795.14 2,710.51   2,728.37
2018-10-12  2,775.77 2,729.44   2,767.13
2018-10-15  2,775.99 2,749.03   2,750.79
2018-10-16  2,813.46 2,766.91   2,809.92
2018-10-17  2,816.94 2,781.81   2,809.21
2018-10-18  2,806.04 2,755.18   2,768.78
2018-10-19  2,797.77 2,760.27   2,767.78
```

- ``BDH`` example with Excel compatible inputs:

```python
In[4]: blp.bdh(
  ...:     tickers='SHCOMP Index', flds=['High', 'Low', 'Last_Price'],
  ...:     start_date='2018-09-26', end_date='2018-10-20',
  ...:     Per='W', Fill='P', Days='A',
  ...: )
```

```pydocstring
Out[4]:
ticker     SHCOMP Index
field              High      Low Last_Price
date
2018-09-28     2,827.34 2,771.16   2,821.35
2018-10-05     2,827.34 2,771.16   2,821.35

## Optimizations

This library uses a global Bloomberg connection on the backend - 
more specically, `_xcon_` in `globals()` variable.
Since initiation of connections takes time, if multiple queries are expected,
manually create a new connection (which will be shared by all following queries)
is helpful before calling any queries:

```python
from xbbg import blp

blp.create_connection()
```

## Data Storage

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.
