Python Package for reading a amibroker database

ami2py

Python Package for reading and writing from and to an amibroker database.
This package is using construct for defining the binary structures used to access the amibroker database, see Construct documentation.
The specification of the binary structure was taken from the official amibroker C++ sdk api documentation.

However, this is not an official amibroker database api.
Therefore, no warranty is given and handle with care.
Improvement requests are always welcome.
This module can be used to create a database and write symbol data to that.
However, it seems to be a good idea to use the official quote downloader program for productive usage.

Examples

Creating a Database from scratch and adding symbol data to the database.

>>> from ami2py import AmiDataBase, SymbolEntry
>>> db = AmiDataBase(db_folder)
>>> db.add_symbol("AAPL")    
>>> db.append_data_to_symbol(
        "AAPL",
        SymbolEntry(
            Close=200.0,
            High=230.0,
            Low=190.0,
            Open=210.0,
            Volume=200003122.0,
            Month=12,
            Year=2020,
            Day=17,
        ),
    )
>>> db.write_database()

Reading a list of symbols contained in the database.

>>> symbols = db.get_symbols()
>>> symbols
["AAPL"]

Getting values for a symbol in a pandas compatible dicitonary format.

>>> data = aapl = db.get_dict_for_symbol("SPCE")
{
    "Open": [20.0,....],
    "Close": [200.0,....],
    "High": [230.0,.....],
    "Low": [190.0,.....],
    "Open": [210.0,.......],
    "Volume": [200003122.0,.....],
    "Month": [12,.......],
    "Year": [2020,.......],
    "Day": [17,........],
}

Todos

• Write tests for intraday data, currently data structures is able to handle intraday data. But no tests had been written, until now. This is considered mandatory to reach version 1.0.0
• Add docstrings to the source code. This seems to be a minor task.
• Currently no real life performance measures have been done.
